Not all tank cars are alike
Tank-car construction depends on the commodity. Pressure rating, insulation, fittings and protective housings vary widely.
How to identify one
The cylindrical tank body is obvious, but exact commodity identification should never be guessed from color or shape alone.
Safety and placards
Hazardous-material tank cars use placards and regulated markings. Railroad Central Station is an educational site, not a substitute for emergency-response guidance.
