The DLR could have been built better right from the start so that more capacity and efficiency were in place since its first day. It was never meant to rival any section of a tube line in capacity per KM.

While the first 2 Skytrain lines only have 80 m stations which are slightly more than half the length of a Montreal Metro train station, there should have been enough level station clearance to eventually double the length of each station. The 3rd line to YVR only has a level station clearance of 50 m, vs. the 152.4 m Montreal Metro stations. The YVR-Canada-Line should have had enough level station clearance to eventually become 160 m in length.
