The given pictures compare the differences of the Toronto Go train station throughout the new design.
It is obvious that the level of transit concourse becomes lower during the period. Besides, the design of the train station will be divided into more parts in the future.
As for the layout of the station before and during the building process, the height of the transit lounge accounts for half of the under part of the station which will be gradually widened during the construction with the help of a framework to hold the pile. In addition, the track level will remain unchanged.
In terms of the complete map of the Go station, there will be no change in the track level. However, the transit concourse will be divided into two parts which are predicted to be a new space serving the same purpose and a new pedestrian retail level underneath.
