Railway Tanker Transporting Dangerous Goods

Rail TDG Standard TP 14877 Update

On March 15 Transport Canada released a notice on the intent to issue a new January 2018 edition of standard TP 14877 “Containers for Transport of Dangerous Goods by Rail” to replace the current 2013 (with Corrigendum) edition.

This is the penultimate culmination of the public process, in part arising out of the Lac Mégantic 2013 disaster, undertaken by a stakeholder Consultative Committee that began in February of 2016.

The main features of the proposed 2018 edition include:

  • Improved usability by incorporating external technical requirements, such as those in Protective Direction 34, 37 and 38.
  • Updated dangerous goods list to align with the 19th edition of the UN Model Regulations. Adjusted special provisions to reflect updated transportation requirements for Sulphuric Acid (UN1831) and Hydrogen Peroxide (UN2014 / UN2015).
  • Updated technical requirements for Class 3, Flammable Liquids and the new tank car specification known as TC 117.
  • Improved harmonization between tank car requirements in Canada and the US, including tank car approvals, tank car design requirements and a new mechanism to secure One Time Movement Approvals (OTMA) – Category 2.
  • Updated material of construction requirements for tank cars, including the addition of stainless steel, normalized steel for dangerous goods classified as a toxic inhalation hazard (TIH) and improved thickness requirements for new tank car construction.
