In the 1990s, my uncle, the mayor of the municipality of Terrasse-Vaudreuil at the time, went to war over the crossing. Now it's 2022, and the issue remains unresolved. Railway transportation is highly profitable, and it would be good if the railways could help construct a viaduct over the crossing or an underpass to improve safety.
There are four railway lines to cross, not two, and that often causes a lot of problems. The first thing to do would be to build a viaduct over the crossing or an underpass.
I would also request training for our firefighters. The number of trains that go through stresses them too. They wouldn't know how to react to a railway incident.
