Westminster tube stationWestminster tube station on the London Underground serves the Circle, District and Jubilee lines. It was re-opened on December 22 1999 as part of the Jubilee Line Extension (although the Circle and District line services never stopped running). A vast 30m (90ft) cave was excavated underneath the old station to house the escalators to the deep-level Jubilee Line, the deepest ever excavation in central London. The station also serves as the foundations for Portcullis House, home to MP's offices.
As with other stations on the Jubilee Line Extension, the Jubilee Line platforms at Westminster have a glass barrier, with its own set of sliding doors, between the platform and the tracks to assist in controlling air circulation (and presumably, extra safety).

The station's cavernous design, by Michael Hopkins & Partners, won it a 2001 Royal Institute of British Architects Award and earnt it a place on the shortlist for the RIBA's prestigious Stirling Prize.
