The Confederation Line project is the first stage in Ottawa’s future light rail network. The 12.5-kilometre electric rail system – to be completed in 2018 – will replace existing diesel powered buses, providing rapid transit between Blair Station in the east and Tunney’s Pasture Station in the west. The route includes 13 stations and a 2.5-kilometre tunnel that will alleviate congestion through the downtown core.

West Portal ramp shoring and excavation prior to the beginning of tunnelling; the portal is one of the O-Train Confederation Line light rail transit (LRT) entrances to/from the tunnel, located just east of Pimisi Station.
