Line 6 (Montreal Metro)

Planned as the first of a series of new "regional metro" lines along existing railways in 1979 (similar in concept to the Paris RER and San Francisco BART), the Ministère de Transport du Québec (MTQ) expected Line 6 to begin service along 23.3 km of Canadian National railway tracks by 1989.

Running along the northern part of the island, it would have passed through the districts of St. Laurent, Ahuntsic, Saint-Michel, Montreal-Nord, Riviere-des-Prairies and Pointe-aux-Trembles.

[1] Planned stations included elevated stops along viaducts, and others at ground level.

Trains would have run in four-car sets during rush hour, and two cars the rest of the day.

Due to an economic slowdown in Montreal, the Line 6 proposal was abandoned in 1985.
