Exo promises detours around closed tunnel

Exo is promising nervous commuters it will keep the Mascouche line running and use a detour around the Mount Royal tunnel, scheduled to close for an indefinite (but fairly long) time at the end of the year. The more numerous users of the Deux-Montagnes line will have to undertake a more tedious route, with a bus navette taking them from Bois-Francs to Côte-Vertu metro and thence downtown.
