The pictures show how a new underground platform and changes were made to the toronto go train station during and after construction.
The illustrations reveal the plan of renovation for Toronto Go Train Station. Overall, the station originally had two levels for boarding and transit, which was further expanded to another level for commercial purposes, while the existing train track level remained operational.
In the past, the train tracks were located above ground, below this level was an underground level used as a path for passengers to transit. A pillar was constructed to support from the bottom of the ground floor down to the deep underground foundation, which was divided into two parts, the exposed part in the basement was relatively smaller, and was increased in size in the extended underground part of the transit path.
From the redesign stage, a provisional support framework underground was erected since the larger part of the foundational pillar was dismantled for the purpose of adding another underground level. After renovation, the temporary framework was removed and the supporting pillar was extended with the same perimeter. The existing transit concourse was slightly raised, and another underground level was opened for retail stores. (176 words)
