Snowdon

Snowdon is a station on the Montreal Metro rapid transit system, operated by the Société de transport de Montréal (STM). It is located in the Snowdon neighbourhood of the borough of Côte-des-Neiges–Notre-Dame-de-Grâce in Montreal, Quebec, Canada. It is a transfer station between the Orange Line and Blue Line, and is the western terminus of the Blue Line.

Overview :
The station was constructed as an anti-directional cross-platform interchange, with three lateral tunnels containing two stories each, joined by four cross-tunnels; both lines therefore have stacked platforms. This layout was intended to allow rapid transfer between a future extension into Notre-Dame-de-Grâce and service to downtown; unfortunately, this service never opened, and the station's layout means that most people who transfer between the blue and orange lines must go down stairs.
