With such a high capital construction cost, its foolish and very short sighted that Vancouver & BC never allowed for enough clearance to eventually have 10 car trains.

At least the first 2 SkyTrain lines have stations that can accomodate a 5 car train. Unfortunatly, the joke that is the Canada embassament Line never allowed enough level clearance for 5 car trains, only a 2.5 car train. Combine short trains with mostly narrow bridges and no interest to build a series of bus-bridges and you have a fine example of congestive planning. Of course no one seems to know where the funds that should have gone towards big city infrastructure went.
