Please see the note below that Maritime-Ontario received from CN Rail…
CN is expecting severe cold weather conditions in our Canadian and US Midwest rail network. As part of CN’s winter preparedness and train operating plan, when cold temperatures fall below -25C, to ensure safe train operations, train length restrictions go into effect.
As a result, our trains operating in the corridors from Toronto and Chicago through to the Prairies have to be shorter trains, which may mean reduced weekly capacity.
To support our winter train operating plan, we have moved crews and locomotives into key locations. We are committed to moving your goods as safely and quickly as possible. However, the weather outlook predicts this Arctic cold will persist for another 5-7 days in key areas.
