No 10 car trains, not even 9 like what the Montreal Metro has. It's been tough enough just to get the first 2 Skytrain lines to handle 5 car trains. The Canada Line, a pathetic 3rd line can ultimately only handle 2.5 car trains.
Short trains & narrow bridges are always great examples of congestive planning in Greater Vancouver.
