Safety communications related to TSB investigation R23D0108: November 2023 train collision in Montréal, Quebec

The occurrence

On November 21, 2023, a Canadian National Railway (CN) train and an exo commuter train collided at the St-Léonard-Montréal-Nord station in Montréal, Quebec. The investigation found that the CN train crew had passed a Restricting signal requiring them to limit their speed and be prepared to stop. However, believing the track ahead was clear, the train accelerated. By the time the stationary commuter train became visible, it was too late to avoid the collision and subsequent derailment.
