Drainage by Application · Transportation & Logistics
A commuter platform, a fare-gate plaza, a busway crossing and a maintenance yard apron are four different drainage problems sharing one property line and one capital project number. Here is how water behaves on each, where the load class jumps four steps in two hundred feet, and what we would put on the submittal — from the boarding edge to the wash slab, and nowhere near the ballast.
A transit property is six paving standards sharing one project number
Walk a commuter rail or light-rail station from the street in and you cross six surfaces built to six different rulebooks: a park-and-ride lot laid to a parking standard, an entrance plaza laid to an architectural standard, a platform laid to an accessibility standard where tolerance is measured in fractions of a percent, a bus bay laid to a highway pavement standard, a garage deck that is somebody's roof, and — where there is an operations facility — a yard apron and pit road closer to an industrial floor than to anything else on site. They shed water differently, they fail differently, and they demand wildly different ratings from anything set into them.
Transit surfaces are also unusually intolerant of ponding. A puddle in a retail lot is an annoyance; a puddle at the bottom of a stair throat, in front of an elevator door, or across the accessible boarding area is a slip claim, an accessibility complaint and a maintenance ticket at once — and on a surface a few thousand people cross before nine in the morning, it gets found the first day it appears. In freeze climates the slow-draining low spot in October is an ice sheet in January at the exact point where people step off a train, and the deicing salt that follows attacks steel edge rails long before it touches the channel body. What the water carries matters too: brake and rail dust, ballast fines tracked off the right-of-way, winter sand, tire rubber on the bus apron, detergent and heavy solids in the yard, plus the cups and ticket stubs that mat across a grate face. Every one of those is a reason to buy more intake area and more sediment capture than the calculation strictly requires.
One boundary before anything else, because it decides whether we are the right supplier at all: we work above the ballast line, and only above it. Everything here is station-and-yard drainage — surfaces people stand on and vehicles drive on. Trackbed, cess and subballast drainage is a separate discipline with its own engineer and supply chain. We do not sell it, quote it, or pretend to know it.
Every drainage need on a station or yard — including the ones we don't sell
Subsurface and under-track systems — not ours, and not a channel drain
Track drainage proper is a subsurface system: perforated collector pipe bedded in washed stone, wrapped in geotextile, running in the cess beside the track or in a subballast blanket beneath it. It belongs to the same family as the french drains used on golf courses, sports fields and residential yards — a gravel-and-fabric trench that intercepts water inside the soil profile. You meet the detail again at a station: embankment underdrain around a station box, underdrain beneath a bioswale at a park-and-ride edge. All of it is engineer-designed and contractor-installed, and none of it is a product we carry. The distinction is worth defending in a meeting, because on transit jobs the two terms get used interchangeably and they should not be. A french drain works below grade on water that has already soaked in; a trench drain works at the surface on water running across pavement right now. A subsurface system does nothing for the sheet crossing a platform or the pond forming in a bus bay. That water has to be caught where it is, which is the layer we sell.
Sumps, pumps and treatment — downstream, by others
A depressed station, underpass, elevator pit or below-grade concourse terminates at a sump. Pumps are not something we sell or specify, and we will not pretend our scope reaches into the life-safety package that usually governs them. Nor will we quote oil-water separators, hydrodynamic separators, interceptors or detention: at a garage apron, fueling lane or wash slab, the separator sits downstream of our trench in the plumbing or civil package, by others. Put that boundary on the submittal in writing. What our layer controls is how much water and grit ever reaches that equipment — a bigger lever on its maintenance cost than most people expect.
Canopy leaders — half ours
Canopies and headhouses concentrate a very large roof into a handful of leaders. The roof drain, leader and boot are plumbing-specification items. Where that leader discharges — at grade, at a column base, into a plaza already carrying its own sheet flow — is our problem, and it is the most under-designed detail we see on station drawings. A leader dumping 300 GPM onto pavers six feet from a stair throat stopped being a roof problem the moment it left the pipe.
The surface-collection layer — ours
Channel and trench drains across platforms, plazas, thresholds, bus lanes and yard aprons. Catch basins at low points with the risers, adapters and outlet fittings that tie them into pipe. Grates in every material a transit site needs, drainage fittings for the conveyance between them, and valve boxes for buried access. At a landscaped park-and-ride edge where a pipe can daylight legally, pop-up emitters and dry wells still have a place, though on most transit sites the civil drawings already name a designed storm connection. One question to ask before you lock in metal near track: on DC traction systems, metallic components close to the right-of-way can fall under the traction-power engineer's stray-current and bonding rules. That is their call, not ours — but it is far cheaper to ask before an edge rail and grate material reach a submittal.
How water actually moves on a platform, a plaza and a bus apron
Start with the platform, because it surprises people. Its cross slope is capped by accessibility — an accessible route runs no steeper than 1:48, and the boarding surface is held to that 2% in all directions. That is barely enough pitch to move water sideways, so platform water travels lengthwise far more than across, gathering as it goes and collecting at the low end, at the stair throat, and against the elevator sill. Above it, the canopy is often wider than the platform it covers and drops its whole roof into two or three leaders. The contributing area is almost never the surface you are looking at.
Put numbers on it with the one rule worth memorizing: 1,000 sq ft sheds about 623 gallons per inch of rain. Take a 450' × 14' side platform — 6,300 sq ft — with a 300' × 16' canopy adding 4,800 sq ft. That is 11,100 sq ft, 0.255 acres, about 6,915 gallons per inch of rain arriving at one line. Run the rational method at a 3 in/hr design intensity with a runoff coefficient of 0.95 for hard paving and you get roughly 0.73 cfs, about 326 GPM.
Now check the outlet, because the outlet is the bottleneck — not the channel. An ACO KlassikDrain K100 6" oval outlet cap is published at 233 GPM (0.52 cfs) at the 9.84" (250 mm) invert band and 264 GPM (0.59 cfs) at the 11.81" (300 mm) band, and that second figure is the largest end outlet in the K100 range. Against 326 GPM a single outlet of any size loses. The honest answers are to fall the run to both ends, or break it partway with an in-line catch basin taking 4", 6" or 8" pipe out the bottom. That is the real design question on a platform: not how many feet of channel, but how many outlets, at what invert, and whether the pipe leaving them has fall — a trade minimum around 1/8" per foot on larger storm lines and 1/4" per foot on small ones. Confirm the invert available at each discharge before you commit to a channel depth; it kills more transit layouts than any other number. Run your own case in the Runoff Calculator, with the method behind it in Sizing for Storms: Estimating Runoff.
Bus aprons concentrate differently. A three-bay loop apron at 260' × 50' is 13,000 sq ft — roughly 8,100 gallons per inch, 0.299 acres. Design it for a heavier 4 in/hr storm at the same 0.95 coefficient and you are at about 1.13 cfs, 509 GPM across one cross-line. Two 6" end outlets total 528 GPM: it passes on paper, and it does not pass in February with half the intake under a mat of leaves and sand. That is exactly when we step to a wider channel with bottom outlets instead of fighting for another end cap. Park-and-ride lots leave trench territory entirely — 500 stalls at roughly 320 sq ft each including aisles is 160,000 sq ft, 3.67 acres, close to 99,700 gallons per inch and on the order of 9.9 cfs at a 3 in/hr storm. Nobody drains that with a channel; that is a piped inlet network your civil engineer sizes, and our part is the basins, adapters and grates feeding it.
Load class from the boarding edge to the pit road
EN 1433 classes are the common language on a transit submittal, and the jumps across one property are larger here than on almost any other site type. A platform and a yard apron can sit two hundred feet apart and four classes apart.
EN 1433 load class across a transit property
Class
Rating
Where it belongs here — and what we think of it
A 15
15 kN · 3,372 lbf
Nowhere on a working transit property. There is no such thing as a pedestrian-only platform — it gets a ride-on scrubber, a pallet jack of vending stock, and a pickup on the emergency access route.
B 125
125 kN · 28,102 lbf
Our floor on platforms and concourses. Acceptable only where you are certain nothing heavier can physically reach the run.
C 250
250 kN · 56,202 lbf
Plazas, forecourts, kiss-and-ride curb lines, station entrances. Our default for anything public a sweeper or EMS unit can drive onto — which is most plazas, whether the drawings admit it or not.
D 400
400 kN · 89,924 lbf
Bus bays, busway crossings, fire lanes, service drives. Minimum for anything a 40-ft transit bus routes over, and the class most often under-specified on a shared plaza/bus-loop surface.
E 600
600 kN · 134,885 lbf
Articulated-bus lanes with braking and turning, garage aprons, fueling lanes. Top of the KlassikDrain K100 grate range.
F 900
900 kN · 202,327 lbf
Yard aprons, pit roads, hi-rail pads, wash slabs — anywhere an outrigger or loaded shop lift can land. PowerDrain territory, and not a place to economize.
Two cautions we repeat on every transit job. The channel and the grate are rated separately, and the installed rating is the lower of the two plus the encasement detail — a Class F grate in a Class C installation is a Class C drain, and the pour is as much a part of the rating as the catalog number. And where the pavement section is written in AASHTO terms, treat the mapping as a trade heuristic only: an H-20 detail assumes a 16,000-lb wheel and HS-25 a 20,000-lb wheel, which puts most bus and yard paving in the Class D to F neighborhood, but EN 1433 and AASHTO are separate systems and a rating under one is not certification under the other. Class-by-class detail is in our Load Class Recommendation Guide.
Where each piece earns its place on a transit site
The platform drip line. The highest-value run on the property: a longitudinal channel just inside the canopy drip line intercepts roof water before it reaches the walking surface, with a short cross-run at the low end for what the 2% cross slope has been pushing lengthwise for four hundred feet. Keep it out of the boarding area where layout allows — and remember the detectable warning strip along the boarding edge is 24" deep and continuous. The channel goes behind it, never through it.
Stair throats, escalator wells and elevator sills. Where water does the most damage, and where it gets left to "the slope" most often. These are almost always depth-constrained by a structural slab, a membrane or a station-box roof a few inches down — and where the habit of reusing the section specified everywhere else falls apart.
Fare-gate plazas and forecourts. Architectural surfaces with real vehicle exposure. Spec the load class for the sweeper truck nobody drew, then choose the pattern — in that order. Unit-paver plazas also need an edge rail that survives pavers being reset around it for twenty years.
Bus bays, busways and kiss-and-ride lanes. Cross-lines at the bay entrance and at the low end of the lane. Buses stop in the same six feet a thousand times a week, so the loading is repetitive and dynamic and the encasement detail matters more than the product choice. Keep slot orientation perpendicular to travel, and check for bicycle-safe patterns wherever a bike lane or shared-use path crosses.
Yards, pit roads and wash slabs. Hi-rail trucks, shop equipment, occasional outriggers, continuous water and detergent. Sediment capture decides the maintenance budget here: an in-line basin with a removable trash bucket keeps grit out of the outlet pipe and out of whatever separator sits downstream, and turns a rodding job into a bucket lift.
Grates. Size intake from the flow calculation, then pick pattern for traffic and accessibility and material for exposure. We won't rebuild the grate catalog here — the range lives in the grates section, from ductile iron and cast iron through steel, with channel grates matched to each system and square and round grates for basins. For a designer-driven plaza, look at the decorative range before somebody proposes a custom casting.
What we'd put on the submittal, zone by zone
These are the picks we actually make on transit packages. The ACO lines are quoted per project and never sold from a cart — an advantage here, because a station package needs cut sheets, load-class documentation and a coordinated bill of material more than it needs a checkout button.
Our default platform and canopy run: 4" (100 mm) internal clear width in polyester polymer concrete, 5.12" (130 mm) overall, edge rail cast integrally into the body, and a 0.5% built-in slope in the numbered sections — installed in sequence they give up to 131'-3" (40 m) of continuously falling trench, about 1/17" of fall per linear foot, with no stepping of the sub-base. On a platform where accessibility has taken your grade away, that built-in fall is the entire argument. Head-of-run sections are 4.72"–4.92" (120–125 mm) deep at 28.1 lbs, so a two-person crew sets them without equipment, and the shared grate range reaches Class E. One thing we insist on: spec the KS100 stainless rail wherever deicing salt lands. The K rail is galvanized steel, the KS rail Grade 304 stainless, and on a salted northern platform the rail fails first — long before the polymer concrete, which is published frost-proof and salt-proof at 0.07% water absorption. Note too that bottom knockouts fall on every fifth sloped channel, which quietly constrains where you can drop out. Request a quote with run lengths and invert.
The boarding-zone grate call — Type 476D and 480D ductile iron
Heel-proof, and hung on slot direction · quote-only
On a platform, grate selection stops being hydraulics and becomes accessibility. The Type 476D longitudinal ductile iron grate carries 2.10" × 0.24" (54 × 6 mm) slots — nothing larger than 0.25" (6.5 mm) — for 22.6 sq in of intake per half meter at 7.0 lbs; the decorative Type 480D Wave gives 0.27" × 2.4" (7 × 61 mm) slots and 27.0 sq in. Both are cast to ASTM A536-84 Grade 65-45-12, rated EN 1433 Class C at 56,202 lbs, and carry ADA-compliant, bicycle-safe, heel-resistant and anti-slip (BPN > 24) designations with factory-fitted boltless DrainLok locking. The mistake we see most often on transit drawings is a longitudinal grate laid with its slots running along the platform. Turn it: the ADA standards allow no opening that passes a 1/2" sphere and require elongated openings perpendicular to the dominant direction of travel. Slot orientation is the difference between a compliant surface and a cane trap, and it costs nothing. More in ADA and pedestrian drainage.
When a structural slab, membrane or station-box roof sits a few inches under the finish, this is the shallowest engineered channel we carry: 3.50" (89 mm) overall depth, 3.15" (80 mm) overall width, a 2" (50 mm) clear opening and a constant 2.90" (74 mm) invert at 18.0 lbs per meter, in galvanized or Grade 304 stainless rail, taking ADA grate patterns in plastic, galvanized steel, stainless and ductile iron. Right at elevator sills, escalator wells and canopy edges where a K100 will not fit. And the limit, stated plainly: the bottom drill-out takes 1.5" Schedule 40 pipe at a published 12.7 GPM. This is a threshold interceptor, not a conveyance spine — catch water with it, then hand the volume to something bigger within a short run.
The plaza and headhouse forecourt spine · quote-only
When plaza arithmetic runs into four figures of GPM, step up in width rather than running two parallel lines and doubling your joints. K200 is 7.87" (200 mm) clear in a 10.24" (260 mm) overall width, 8.86"–9.06" deep at the head of the run, 83.6 lbs per meter; K300 is 11.81" (300 mm) clear in a 14.17" (360 mm) width, 12.6"–12.8" deep, 132.6 lbs per meter. Both keep the 0.5% built-in slope. The trade-offs are real — setting a K3 section is equipment work, not crew work, and the deeper invert has to actually reach your discharge, which is why invert-at-outlet is a required field on our quote form. On exposed plazas where freeze-thaw and appearance both govern, ask us to price BG Filcoten alongside it: fiber-reinforced high-performance concrete in 4" Tec V100, 8" Tec V200 and 12" Tec V300 widths with its own grate range.
Where the pavement stops being a plaza and starts being a road. Same 4" (100 mm) clear opening as the K100, in a 6.30" (160 mm) overall width at 48.1 lbs per meter, same 0.5% built-in fall across 40 sloped and 9 constant-depth sections — but with a ductile iron edge rail cast into the polymer concrete body. The reason to move here is not capacity; it is that iron edge, because the edge is what fails first under a bus wheel hitting the same joint ten thousand times. Pair it with the 96082 PowerLok slotted ductile iron grate: 0.43" × 1.98" average openings, 25.70 sq in of intake per 19.69" section, 12.30 lbs, EN 1433 Class F, boltless PowerLok locking, separately listed against FAA airside guidance at a 200,000 lb proof load — a useful sanity check when an agency asks whether a bus-lane rating has headroom. Where the crossing is also a pedestrian route — a BRT median station is exactly that — specify the 96096 longitudinal grate instead: same Class F, same FAA listing, 1.36" × 0.45" openings and 25.20 sq in of intake, and it carries the ADA-compliant designation the slotted pattern does not. Half a square inch of intake is a rounding error next to that label.
The yard apron, pit road and bus-wash slab · quote-only
Yards are where we stop optimizing for appearance and start optimizing for the wash cycle. S200K is 8" (200 mm) clear, S300K is 12" (300 mm) clear, both with the ductile iron edge rail and both reaching Class F with the right grate. The 99592 4-bolt slotted ductile iron grate for the S300K gives 0.71" × 3.75" average openings and 115.50 sq in of intake per 19.69" section — more than four times what a K100 half-meter ADA grate offers, which is what a wash slab needs when a bus dumps its water all at once. On yard and remote runs we specify the bolted grate with the tamper-resistant bolt (ACO part 138127) rather than the boltless version, and we say why out loud: that grate is 50.20 lbs of ductile iron with scrap value, on a slab nobody watches at night. Scope reminder — whatever separator the wash bay needs sits downstream of this trench, by others.
Lots get collected, not trenched. A 24" basin measures 24-3/4" × 24-3/4" × 24" deep and accepts 3" and 4" Schedule 40, sewer, drain, corrugated and triple-wall pipe, 6" and 8" sewer, drain and corrugated, and 10" and 12" sewer, drain and dual-wall corrugated — the workhorse junction where a lot's network changes size. Step down to 12" or 9" basins on landscape islands and walkway edges, or take a kit where grate and adapters should ship together, and grate every one to the load class of the pavement around it — cast iron where wheels cross, never plastic in a drive aisle. Inside a KlassikDrain run, the in-line catch basin is the piece that earns its keep: 19.69" long, the same width as the channel and visually continuous with it, rated EN 1433 Class E (134,885 lbs), with a removable polypropylene trash bucket, 12.3 gallons to the grate seat and Schedule 40 cut-outs for 4", 6" and 8" outlet pipe. It buys you a second outlet mid-run and a sediment trap in the same 20 inches.
Employee lots, access drives and agency maintenance stock
Not every line on a transit property deserves polymer concrete. Employee lots, access drives, layover parking, shelter pads and yard perimeter work rarely justify it, and Dura-Slope is the sensible answer: HDPE body with a 0.7% built-in slope, ProFit grate locking, the DuraLoc integral joint lock, tongue-and-groove joints and a bottom outlet in each section, light enough for a small crew to set by hand, with neutral sections where the invert must stay flat — full grate matrix in the Dura-Slope FAQs and resources. Where a run needs to be wide and shallow rather than long and deep, the 8" and 12" Pro Series channels take more water per inch of depth; the 12" ductile iron heavy-traffic grate opens 68.64 sq in per foot against 48.77 sq in per foot for the light-traffic plastic, which is the whole argument for iron on an access drive. These are also the lines agencies stock for their own forces, and we will quote a stocking package alongside the station submittal so a shift supervisor isn't sourcing a replacement grate from three vendors at 6 a.m.
Where a specification names a line we do not stock — ABT, EJ, U.S. Foundry, or Josam's Pro-Plus and Lite Line trench systems — we quote those on request as well. Send the specified model and we will price it rather than let a substitution surprise you at submittal review.
What we need to price a station or yard package
Quote-only lines like KlassikDrain, PowerDrain and MiniKlassik are priced per project, which suits transit work: the deliverable is a submittal, not a shopping cart. What we need is short.
Run length per zone, and whether each run is sloped or neutral.
Required load class per zone — or send the pavement detail and we'll read it with you.
Invert depth available at each discharge point. This kills more layouts than anything else on the list.
Grate material, pattern and finish, plus the lockdown requirement: boltless, bolted, or tamper-resistant.
Design storm intensity and contributing area, if your civil engineer has set them.
Any agency approval, submittal format or domestic-content requirement. If the project is federally funded and carries one, tell us before we quote and we will put the question to the manufacturer in writing rather than guess — we do not make compliance claims on anyone's behalf.
Send it through the quote request form and we will come back within one business day. If the package spans several zones, quote them together: freight alone usually justifies it, and it keeps grate patterns consistent across the property instead of four textures on one platform.
Questions agencies, GCs and specifiers send us
Do you supply track, cess or subballast drainage?
No, and we would rather say so on the first call than three weeks into a submittal cycle. Under-track drainage — cess drains, subballast blankets, perforated collector pipe bedded in washed stone and wrapped in geotextile — is track engineering: designed by the track or civil engineer, built by the trackwork contractor, and not something we sell or quote. Everything we supply sits above the ballast line: platforms, canopies, plazas, station entrances, bus bays and busways, park-and-ride lots, yard aprons, pit roads and wash slabs.
What load class does a platform need, and what does a bus lane need?
EN 1433 Class B (125 kN, 28,102 lbf) is our floor on any platform, because even a pedestrian-only platform gets a ride-on scrubber at 4 a.m. and a pickup on the emergency access route. Plazas and kiss-and-ride lanes a sweeper or EMS unit can reach earn Class C (250 kN, 56,202 lbf). Bus bays and busway crossings start at Class D (400 kN, 89,924 lbf); articulated-bus lanes with hard braking belong at Class E (600 kN, 134,885 lbf); yard aprons, pit roads and wash slabs at Class F (900 kN, 202,327 lbf). Treat AASHTO mappings as a trade heuristic only — an H-20 detail assumes a 16,000-lb wheel and HS-25 a 20,000-lb wheel — because EN 1433 and AASHTO are separate systems, and a rating under one is not certification under the other.
How shallow can a channel go at a station threshold?
The shallowest engineered channel we carry is the ACO MiniKlassik K50/KS50: 3.50" (89 mm) overall depth in a 3.15" (80 mm) overall width, with a 2" (50 mm) clear opening and a constant 2.90" (74 mm) invert. Know its limit — the bottom drill-out takes 1.5" Schedule 40 pipe at a published 12.7 GPM, so it is a threshold interceptor, not a conveyance spine. The next step up, an ACO KlassikDrain K100/KS100 head-of-run section, is 4.72"–4.92" (120–125 mm) deep on a 4" (100 mm) clear width. Those are channel bodies, not blockouts: the recess has to be deeper by whatever bedding and encasement your engineer accepts, so settle that number before the slab is formed.
How many outlets does a platform trench run actually need?
Count outlets, not channel feet. Use 623 gallons per 1,000 sq ft per inch of rain. A 450' × 14' side platform is 6,300 sq ft and a 300' × 16' canopy adds 4,800 sq ft, so 11,100 sq ft — 0.255 acres — feeds one line, about 6,915 gallons per inch of rain. At a 3 in/hr design intensity with a runoff coefficient of 0.95, the rational method gives roughly 0.73 cfs, about 326 GPM. The ACO K100 6" oval outlet cap is published at 233 GPM (0.52 cfs) at the 9.84" invert band and 264 GPM (0.59 cfs) at the 11.81" band — the largest end outlet in that range. One outlet of any size loses. Fall the run to both ends or break it with an in-line catch basin, and leave margin for the grit and litter that will partly block whatever you choose.
Are the grates ADA-compliant and heel-proof for a boarding area?
The patterns we put on platforms are. The ACO KlassikDrain Type 476D longitudinal ductile iron grate carries 2.10" × 0.24" (54 × 6 mm) slots — nothing larger than 0.25" (6.5 mm) — for 22.6 sq in of intake per half meter, cast to ASTM A536-84 Grade 65-45-12 and rated EN 1433 Class C at 56,202 lbs. The decorative Type 480D Wave runs 0.27" × 2.4" (7 × 61 mm) slots for 27.0 sq in per half meter at the same class. Both carry ADA-compliant, bicycle-safe, heel-resistant and anti-slip designations. Orientation matters as much as slot size: the ADA standards allow no opening that passes a 1/2" sphere and require elongated openings to run perpendicular to the dominant direction of travel.
Can the grates be locked down against theft on an unstaffed platform?
Yes, and on an unstaffed stop or an open busway we treat it as a requirement rather than an option. KlassikDrain grates secure with the boltless DrainLok or QuickLok systems, which hold the grate without hardware and release for cleaning. PowerDrain grates come in a boltless PowerLok version and a 4-bolt version, and the 4-bolt grates accept an optional tamper-resistant bolt, ACO part 138127. Scrap value is the honest reason: a single 99592 slotted ductile iron grate for the S300K weighs 50.20 lbs. On a remote yard or a park-and-ride edge we spec the bolted grate and accept the slower cleaning cycle.
Where a transit property meets the rest of the site
ADA and pedestrian drainage goes deeper on grate patterns, slot orientation and cross-slope along the accessible route, and it is the page to hand an architect arguing for a custom casting on a boarding area. Parking structure drainage is the right reference for a park-and-ride deck, where the floor is also somebody's roof. Heavy traffic drainage treats Class D as the normal case rather than the exception, which is the correct mindset for a busway. And fleet and truck wash drainage covers the bus wash bay, including the same honest split between the trench we sell and the separator downstream, by others.
