The picture illustrates the layout of the Toronto Go Train Station before, during and after the redevelopment. Overall, the platform consisted of two conventional levels for boarding and transiting and was expanded deeper for a third one, catering for commercial purposes. Despite this change, the station remained operational.
Before the construction, the station had two separate levels: the train track on the top and a transit concourse below, with the latter being supported by a pillar with a wider foundation.
During the construction of the second level, specialized machinery was used, with most of the ground and the foundation being removed. Scaffolding was also erected, and a temporary staircase was built for passengers to travel and maintain transportation services.
After renovation, a new level for retailing was opened. The pillar was reconstructed throughout the two levels at the same perimeter with a column footing spread. The transit level was also raised slightly higher.
