Even though there were apparent budget limits through the years, the first 2 SkyTrain lines still should have been designed with a provision to have at least 152.5 m long stations. The SkyTrain-Canada+Line should have been designed to ultimately have 160 m long stations.
Instead, the first 2 SkyTrain lines only have 80 m stations & the joke that the Canada Line is, only has a 50 m limit.
