Maximum Train Length (in feet) Allowed at Specific Temperatures

CN has adopted a four-tier system, to address the impact of severe winter temperatures and ensure safe operations under these conditions. This chart shows CN’s train length safety driven policy for cold-weather operations. Reductions in train length are required once temperatures are -25°C or below, and were updated from previous years for greater safety.
