Two Dome Rotating Railcar Hazmat Training Prop

Train crews on railroad tank car dome leaks with the car upright or rolled over up to 100 degrees, using a DOT 112 High Pressure Dome and a DOT 117 General Service Dome.

Why Use the Two Dome Rotating Railcar Training Prop?

The Two Dome Rotating Railcar replicates a railroad tank car in both the upright position and a rolled-over position, up to 100 degrees in either direction in 15-degree increments. It gives crews typical access, elevation, and working space around two railroad tank car domes, one DOT 112 High Pressure Dome and one DOT 117 General Service Dome, in multiple positions.

Why Use the Two Dome Rotating Railcar Training Prop?

Training Modes & Remediations

High Pressure Dome (DOT 112)

Liquid line valve leak: isolate and secure the leak source
Vapor line leak: isolate and secure the leak source
Pressure relief device leak: cap or isolate the relief valve as appropriate
Valve open from vibration: close the valve to mitigate
Valve loose in its mounting: tighten the mounting hardware to mitigate

General Service Dome (DOT 117)

Eduction valve leak: close or secure the valve to mitigate
Air connection valve leak: close or secure the valve to mitigate
Visible vapor leaks: simulated using a water and compressed air mixture

Setup and Transport

The Two Dome Rotating Railcar is manually operated and requires a user-provided source of water and compressed air. It ships fully assembled, can be offloaded onto a concrete surface, and is fully operational within minutes. Weighing a fraction of an actual railcar, it transports easily on a standard lowboy trailer.
