Cold weather and snow can impact train braking systems. For your safety, the train is designed to brake if any issues are detected.
Exo trains are equipped with air brake systems that use compressed air to apply the brake shoes to the wheels and to the brake discs located on the axles.
In order to act rapidly, we deploy a high number of technicians in winter.
We are also in the process of upgrading various components on our MR-90 railcars to prevent recurring problems.
Moisture must not get into the braking system (connections, valves, tanks) because if a component freezes, the brakes will be applied.
We’re replacing the original, 23-year-old air dryers with new ones in order to adequately remove moisture in the system.
During snowstorms or rapid changes in temperature, the valves located beneath the railcars may be hit by all sorts of debris (ice, snow), which creates an imbalance in the system.
We’re installing valve deflectors and protectors beneath the railcars to minimize impacts.
In winter, pressure sensors and valves can freeze.
We’re adding heating elements to certain critical air system components beneath the railcars, and relocating other braking components to compartments inside the railcars.
To ensure the electrical braking panels operate correctly, we are replacing certain contacts with new ones on critical components.
