Railcar Training – Photos of all the working parts.

Railcar Training

Imperial County CA – The HEAT team hosted Rail Car training with Union Pacific Railroad and HazSim as part of a day long regional training involving several agencies.  A picture speaks a thousand words so below is a series of pictures with explanation by HMN contributor Jeff Zeintek, author of the HazMat Operations Field Guide. Study up and see link to quiz at bottom of page – Hint: this page will help.

Dome housing on a high pressure tanker containing the liquid and vapor valves. This assembly is on top of high pressure cars that always carry hazardous materials. Liquid lines run the long axis of the tanker and vapor lines are always short side of tanker. Magnetic gauging device is in the middle.

U.P. states 75% of incidents for leaks inside the dome housing is a vapor or liquid line that is not properly closed. Before installing the "C" kit, check if the valves are closed.

Mainway for General Service Car


hazmatnation-high-pressure-rail

High Pressure Rail car – Highest pressure is 600psi, carry only HazMat, are loaded and unloaded from the top ONLY.


hazmatnation-general-service

General Service Tanker can handle up to 100 psi, have fittings and valves on the bottom, and can carry just about anything.


hazmatnation-corrosive

Corrosive Acid tanker is considered a non pressure tanker, and commonly have a red stripe but not always, they carry everything from water reactives and products heavier than water. If the PRD activates it may not re-seat and the PRD operates at 100% of tanks max operating pressure.
