Transport Canada is proposing a further upgrade to rail tanker cars that haul flammable materials. The latest proposals would require shippers to upgrade tank cars to a standard called TC-117 by 2025. Highlights of the standard:

  • Improved shields at the top of the tank car to better cover the pressure release valve from damage in a derailment
  • A full shield to protect either end of a tank car from puncture
  • A thermal shell to better shield tank cars from fire
  • Steel used to build the cars would be thickened to 9/16th of an inch from 7/16ths.
