TfL Sub-Surface Lines Power Upgrade
PRS was commissioned to design 3 new substations as part of the power upgrade of the Sub-Surface Lines for London Underground. Upgrading the SSL network introduced new rolling stock on the Metropolitan, District and Circle Lines. PRS designed and obtained planning consents for the new sub-stations at Edgware Road, Farringdon and West Ham.
The Edgware Road sub-station is designed with the collaboration of the artist Jacqueline Poncelet, who is preparing a public art installation for the enamelled panels enclosing the sub-station.
Wrapper is a permanent work of art by Jacqueline Poncelet, made especially to clad the new London Underground building next to Edgware Road (Circle line) Tube station. The work, created in vitreous enamel, dresses the building in a grid of patterns developed by the artist.
At Farringdon, the existing structure on the site will be demolished and the new sub-station will be below street level in the existing cutting, opening up key views across the railway tracks towards St Paul's Cathedral.
At West Ham the new substation is close to the Tube station, within the Olympic site. It was designed to be part of the ODA's vocabulary for Olympic infrastructure buildings, using dark brick and landscape.
