A switch is a movable rail that connects two tracks. When the switch receives an electronic signal, it moves to the left or right to “switch” the train to another track. If this system doesn’t operate correctly, two trains could collide!
As the switch must move to the left or right on the ground, in an open-air environment, it is at the mercy of weather conditions.
In winter, the snow and ice can prevent it from moving, and during periods of thaw, it is flooded with melting snow and rain.
In these situations, the switches can malfunction or stop working altogether because of a short circuit. Rest assured that for safety reasons, we stop rail traffic in order to resolve any situations that occur.
It used to be that train conductors would have to free the switches from ice and snow themselves.
These days, the switches are protected by:
However, these systems are not always powerful enough to combat harsh weather. In collaboration with our partners, we’re currently upgrading our switch warmers to make them more effective.
In the meantime, exo is deploying additional staff to ensure the switches operate correctly and improve services throughout the network.
