Designed to Toronto Green Standards, the Sheppard East LRT Station will be the transfer hub between the extended Scarborough RT line and the proposed new Sheppard LRT line. The former is being upgraded to use the same low-floor light rail vehicles (LFLRVs) planned for the new Sheppard LRT line.
The two-level station contains a 90 metre platform and pedestrian concourse levels. Immediately north and south of the station lie, respectively, a tail track for train storage and a cross-over. Other non-revenue service infrastructure include LRT connection tunnels between the Sheppard and Scarborough lines, a new entrance portal on Sheppard Avenue, and an electrical substation at grade. Exiting the station, pedestrians continue their journey at the bus terminal or adjacent passenger pick-up and drop-off. To accommodate several project components, demolition of some low-rise buildings northeast of the site is required.
Challenge: Of primary concern were existing site constraints and proposed construction phasing. The former included consideration of the Chinese Cultural Centre’s (CCC’s) southeast corner infringing on the station’s right-of-way. Phasing complexity resulted from the original schedule which called for the Sheppard LRT to be built and operational prior to construction of the new station.
Solution: Excavation support system details were developed to address the close proximity of the CCC’s building footprint, and provide enough support to limit settlement of its foundations. The station elements were designed to be built in stages to allow for simultaneous construction of the station and continued service of the Sheppard LRT.
