London Underground Piccadilly Line Interim Control Upgrade (PICU) Project
The London Underground Sub-Surface-Rail Upgrade Programme (SUP) is upgrading the SSR lines to a new moving block signalling system which will be controlled from a new Signal Control Centre at Hammersmith. It is anticipated that the Piccadilly Line will also receive an upgrade but this will not occur until post 2022, until which time the line shall remain on the legacy fixed block signalling system. The purpose of the PICU Project is to facilitate the move of the fixed block areas of the Piccadilly Line to a new Signal Control Centre within the same timescales as the re-signalling and movement of the District Line controls.
ARK were asked to provide a complete Signalling Design team to undertake the Design Management and Detailed Signalling Designs for the following Project deliverables:
- Local signalling interface replacement at Cockfosters, Oakwood, Arnos Grove, Wood Green, King’s Cross, Holborn, Down Street, Hammersmith, Turnham Green Acton Town, Northfields, Boston Manor, Hounslow Central, Hatton Cross, Heathrow T123, Heathrow T5, Ealing Common, Hanger Lane Junction, Ealing Broadway & South Harrow.
- Signalling indication collection at Finsbury Park, Barons Court and Earl’s Court.

- A centralised regulation and junction management system in conjunction with a new user GUI interface.
- Maintainer Terminal Facilities (Local Maintainer Terminals in the IMRs and a Remote Maintainer Terminal at the Control Centre).
