Learn how exo ensures your safety when track signalling is affected by winter weather conditions such as snow, freezing rain, fog, and more.
Signal lights are used to control train traffic, notably when trains are running in the same direction, on the same track. For example, the exo1 Vaudreuil-Hudson line is divided into sections (called “blocks”). The signal lights tell a train when it must stop at a block or when it may proceed to the next section.
The majority of signalling panels are owned by our partners (CN) and (CP).
Signal lights are powered by electrical circuits in the rails. In winter, precipitation such as rain, snow and ice can disrupt their operation and cause short circuits in our systems.
In this situation, exo follows a three-step process to ensure your safety.
This situation may result in delays, but our priority is to ensure your safety until your arrival.
Poor visibility of signals due to snow, strong rain or fog requires locomotive engineers (who drive the train) to reduce their speed.
