As long as the REM trains can eventually become double their length, then Montreal can avoid the Vancouver LRT delema. While short and frequent trains can be an initial cost saving measure, there should always be a provision to eventually have longer stations and trains. The joke that is the Canada Line wasn't designed to ever have stations long enough to accomodate 5 car trains. The ridiculous 2 car trains can only be lengthened up to a 2.5 car train, due to the absurd 50m stations.
