One station, $2.5 billion in savings?
Possibly one. A single station in Ahuntsic, near Sauvé metro, fed by express shuttles on bus lanes that are genuinely enforced, would let Alto’s trains cross Laval without stopping and avoid most of a roughly 15 km tunnel under Mount Royal: on the order of $2.5 billion, by the author’s estimate. It only works if getting to the station is fast, which is where the savings would go.
