Ultra-Track Pans

Capture hazardous spills from railroad tanker cars

Ultra-Track Pans have been designed to provide railroad spill containment at industrial rail sidings and locomotive maintenance facilities.  The modular design can be used for spill control for everything from small drips during maintenance to catastrophic spills from tanker cars.

  • Available in virtually any length, Ultra-Track Pans may be used to collect small spills and leaks OR to capture and channel off significant spills caused by defective equipment or a major overflow.
  • Prevent costly cleanup and regulatory fines from railcar spills and chemical spills.
  • Modular Track Pan design can be customized to meet your specific railroad spill containment needs.
  • An economical, easy to install railroad spill solution.
  • Long work life - Estimated to perform 20-30 years.
Key Features:
  • Modular design - Center and Side Pans are 53.5" long; railroad spill containment areas can be easily assembled to any length desired
  • All-polyethylene construction - Rugged Track Pans withstand harsh chemicals and are designed to function in temperatures ranging from -40°F to +140°F
  • UV inhibitor in polyethylene resin resists degrading effects of sunlight, adding years to outdoor service life. 
  • Sealed System - Polyethylene gaskets keep spills from falling between the rails and Pans.
  • Trucks and other vehicles can drive over Track Pans with grates in place (NOTE:  To drive over Track Pans, firm footing must be beneath the Pans; also must "ramp up" to Side Pans with asphalt or concrete)
  • Below grade piping - All Center and Side Track Pans are molded with pipe fitting locators at their lowest point. Below grade piping can be installed to channel large spills to oil/water separators, holding ponds, etc.  More info.
  • Protected by the industry’s strongest warranty - Five (5) years against any material or workmanship defects.  Learn more.

  • Unique stormwater feature is designed to eliminate "pooling" of rain that falls on top of the Center Pan Covers; rain is channeled onto the ballast between the tracks, stays out of the Pans.
  • Low Maintenance - unlike carbon steel track pans, Ultra-Track Pans will not rust or corrode. Polyethylene resin is treated with a UV inhibitor, resists degrading effects of the sun.
  • Low Cost Installation — Lightweight Track Pans can be easily installed without heavy lifting equipment, i.e., forklifts, cranes, backhoes, etc. Minimal tools and labor required.
  • Slip Resistant Surfaces - Pans, grates and covers have been designed with safety in mind. All top surfaces resist slips when wet or oily.

  • Optional Track Pan Covers keep rainwater out of the Pans, providing effective stormwater management.
  • Polyethylene Covers are left in place until the railcar(s) arrive to be off-loaded or loaded. Lightweight covers mechanically lock into the polyethylene decking and will not blow off in windy conditions.
  • Meets SPCC and EPA Stormwater Management Regulations.
  • Also meets New York State Chemical Bulk Storage Regulation Section 599.17c — Secondary Containment for Transfer Stations.


Advantages of Track Pans vs Competitive Products
  • Easy Installation: Lightweight, smaller Pans are very easy to move around and install without heavy equipment
  • Chemical Resistance: Polyethylene construction has excellent chemical resistance - better than metal and other materials.
  • Patented Gasket System: Seals against the rail eliminating a potentially large leak point.
  • Grating is Included: All Pans come with grates as part of the design/integrity for walking on or setting up drive over points. Personnel do not have to walk in spilled product in Pans due to grating in every pan, reducing liability.
  • Modular: If something gets damaged, only a small section will need to be replaced.
  • Patented Horizontal Flow: Flow-Through Channels and bulkhead fittings allow spills to travel from Pan to Pan. Track pans, of all kinds, have limited capacity, so routing a spill sideways and then through below-grade piping is very critical.
  • Patented Stormwater Protection: When optional covers are installed, any rain water that collects on the Center Cover is directed to the patented stormwater feature that allows the water to drain to the ballast below the Pans.
  • Multiple Drain Capacity: Track Pans are designed so they can accommodate multiple drains in as many Pans sections as desired.
  • Covers: Available to keep rainwater out of the Pans.
  • Crude Oil Applications: Viton gaskets available for installations in crude oil loading/off-loading areas.
  • Longevity: Estimated 20-30 year work life.

Frequently Asked Questions

1. How long will Ultra-Track Pans last in the field?
Under normal working conditions, the Track Pans should last from 20 to 30 years in the field. Due to rugged conditions expected at rail sidings, the Track Pans are molded in nearly twice the thickness of standard containment products manufactured by UltraTech. The black color, combined with an ultraviolet (UV) ray inhibitor added to the polyethylene resin, helps protect the Track Pans from harmful effects of the sun.

2. How much containment capacity do the Track Pans have?
Without Grates, each Center Track Pan holds 30 gallons and each Side Track Pan holds 25 gallons. Each Track Pan Grate displaces 6 gallons of fluid. Therefore, each Center Track Pan with Grates holds 18 gallons and each Side Track Pan with Grates holds 19 gallons. Ultra-Track Pans are connected together with bulkhead fittings. One (1) bulkhead fitting is used to connect each Side Track Pan "end to end" and two (2) bulkhead fittings are used to connect each Center Track Pan “end to end”. The patented bulkhead fitting design allows spilled fluids to travel from one Track Pan to the next, thereby increasing capacity as the spill travels over the length of the Track Pan System.

3. How much maintenance is required to use the Track Pans correctly?
The Track Pans are virtually maintenance-free. Visual inspection of the sealing gaskets located between the rails and Pans should take place every six (6) months. If Track Pan Covers are used, the sealing gasket located inside each Center Cover “spout” should also be visually inspected every six (6) months. In addition, if Covers are used, leaves and other debris that may inhibit stormwater flow through the “stormwater ports” (located in the Center Track Pan Stormwater Feature) should be removed when present.

4. What are the Track Pan sealing gaskets made of?
The gaskets that seal between the Pans and tracks are closed-cell polyethylene foam. The closed-cell material will not soak up any fluid.

5. What are the Track Pans, Grates, Covers and bulkhead fittings made of?
All of these items are made of polyethylene. Coupled with the polyethylene track gaskets, the Track Pan product line offers consistent chemical compatibility. Note: Standard gaskets for the bulkhead fittings are EPDM – other materials are available if necessary.

6. What benefits do the Track Pan Covers provide?
Most importantly, the Track Pan Covers keep rainwater out of the Pans. This benefit helps facilities meet various Stormwater Management Requirements. If the Track Pan System uses “below grade” piping that leads to an oil/water separator or other treatment processes, the Covers eliminate the costs associated with treating clean stormwater. Track Pan Covers also keep debris out of the Pans.

7. How do the Grates and Track Pan Covers function together?
Center and Side Covers have molded-in "thumbs" that protrude from their undersides. These "thumbs" friction fit into the grates, allowing the Covers to stay in place in windy conditions. The Grates also provide structural support for the Covers, allowing foot traffic on top of the covers.

8. How chemically-resistant are the Track Pans?
The all-polyethylene Ultra-Track Pans offer excellent chemical resistance for a broad range of acids, caustics, corrosives, solvent, oils, diesel fuel, etc. UltraTech’s engineering staff is available to review specific chemicals upon request.

9. Railcar loading/unloading areas tend to experience high foot traffic. How do the Ultra-Track Pans address OSHA “slip and fall” issues? 

All top surfaces of the major Track Pan components feature a slip-resistant design. Grates and Covers have a raised, molded-in texture that is very similar to a diamond plate design. The inner surface of all Center and Side Track Pans has a surface that is similar to 80 grit sandpaper.

10. What is the working temperature range for Ultra-Track Pans?
-40° F up to + 140° F

11. Does “wind chill” have any effect on the Track Pans?
No effect.

12. What equipment and tools are required to install Ultra-Track Pans?
Metal rake, shovel, sledgehammer, two 12” bar clamps, two pieces of wood 1” x 4” x 48”, two “slip sheets” approx. 10” x 60”, and a utility knife are typically required.
No heavy equipment required.

13. Do I need to order gaskets and bulkhead fittings separately when purchasing Ultra-Track Pans?
No. Gaskets and bulkhead fittings are standard components and are packaged inside each Track Pan shipping container. Note: If planning to install below grade piping, 3” diameter bulkhead fittings to connect to piping must be ordered separately.

14. How are the Track Pans shipped?
Each Track Pan is boxed separately to assure they are protected properly during shipment. The modular units stack neatly on wooden shipping pallets via LTL or full truckload shipments, depending on the size of the order.

15. Have the Ultra-Track Pans been designed to be connected to “below grade” piping to allow large spills to be channeled to oil/water separators, holding tanks, etc.?
Yes. Center Pans and Side Pans have molded-in recesses at their low points. The recesses are shaped like large “hockey pucks” and can easily be drilled out for 3” diameter polyethylene bulkhead fittings. (Click here to see pictures of a below-grade piping installation.)

16. Why are there multiple pipe recesses molded into each Track Pan?
The location and spacing of railroad ties along a set of rails are not entirely predictable. We have provided multiple pipe recesses to guarantee that at least one recess can be used for piping without disturbing any ties.

17. Do I have to connect the Ultra-Track Pans to below-grade piping?
No. The pipe recesses give you the option to do so if desired. Many users are concerned only with capturing small spills and leaks and do not have the desire or need to pipe below grade.

18. Will UltraTech provide assistance to help determine below-grade piping specifications and design?
Yes. As potential Track Pan projects move forward, our engineering staff will provide design assistance upon request.

19. Can Ultra-Track Pans be installed on a curved track?
Yes. The modular design of the Track Pans allows them to follow along a curved track up to 12 degrees without any customization. Please contact UltraTech for technical assistance on any track with a curve greater than 12 degrees.

20. Can Ultra-Track Pans be installed on any tracks, regardless of rail weight?
(Note: Rail weight is defined as the number of pounds per yard of rail length.)
Ultra-Track Pans have been successfully installed on rails as light as 65 lb. All rails greater than 65 lb. work very well with Ultra-Track Pans. Rails that are less than 65 lbs. are not feasible as the rails are too short to allow proper clearance.

21. Upon placing an order for Ultra-Track Pans, does UltraTech need to know the rail weight of the track?
Yes. Please click here to download a worksheet that details a cutaway of a standard rail and tie plate. We will need all of the information in order to determine the correct gasket design that the installation will require.  If your installation location has pandrols, we will also need the information on the second page of the worksheet.

22. Does UltraTech offer turnkey installation service for the Ultra-Track Pans?
Yes. UltraTech has personnel qualified to install Track Pans, with or without below grade piping. UltraTech personnel will travel to installation sites on a contract basis.

23. What length Track Pan System is required to handle a typical railcar or locomotive?
Railroad tanker cars typically range from 35 – 60 feet. Each Ultra-Track Pan is 53.5” (4 ½ nominal feet) long and can be configured to virtually any length desired.
Locomotives typically require a 60-foot Track Pan System.

24. Can vehicles be driven over the Track Pans? 

Yes, provided the following:
Track Pan Grates are in place in each pan.
Adequate support (i.e. compacted soil) is provided under each Pan.
If side Pans are installed, concrete must be poured to “ramp up” to the outer sidewalls of the Side Pans.
Note: Vehicle weight limitation of the Track Pans is dependent on the strength of the bedding material under the Pans. UltraTech engineers are available to provide guidance in specifying bedding material, etc.

25. Can vehicles drive over the Track Pans WITH Covers in place?
UltraTech does not recommend driving over the Track Pans with Covers in place. We recommend removing the Covers before driving vehicles over the Track Pans.

26. When clean stormwater (rain) falls on top of Track Pans with Covers in place, where does the water go?
Side Track Pans - when installed, the Side Pans are positioned at a slight angle, sloping away from the tracks. The rain that falls on top of the Side Pan Covers, runs off the outside of the Covers, just as rain runs off the outside edge of a rooftop. Center Track Pans - because Center Track Pans have a rail located on both sides, it is not possible to channel rain off to either side. UltraTech has patented a means to channel clean stormwater onto the ballast beneath the Center Track Pans, keeping rain out of the Center Track Pans. The graphic below shows the path that rain follows once it falls on top of the Center Track Pan Covers:
