Bristol Area Signalling Renewal & Enhancement

Resignalling:

• 703 SEUs (signalling equivalents) including mid-platform signals at Bristol Temple Meads to replace St Andrew’s Crosses
• Bristol South resignalling was excluded as it is outside the geographical area of Overhead Line Equipment (OLE).

Electrification:

• immunisation of signalling equipment
• replacement of signal structures if foul of OLE gauge or less than 15 years remaining life
• installation of fibre optic cable and RSC (Return Screening Conductor) in the OLE area.

Enhancement:

• full scope of Filton Bank 4-track option including track, civils and signalling
• Intercity Express Programme (IEP) Depot Connection at Stoke Gifford including a new crossover
• Bristol Parkway capacity improvement was excluded from the scope at this stage.

Bristol Area Signalling Renewal & Enhancement

The project outputs are:

• an immunised and re-gauged signalling system ready for electrification by 2016
• a signalling system relockedand recontrolled under the ‘85% compliance approach’ which assumes existing signal positions remain largely unchanged
• the re-control of the Bristol Power Signal Box area (excluding Bristol South) signalling to Thames Valley Signalling Centre in line with the National Control Centre Strategy
• work to signal structures tomake signals safely maintainable under OLE
• installation of the RSC in accordance with the Immunisation Strategy
• installation of a fibre-optic cable in the troughing for the IPC related to the OLE Supervisory Control and Data Acquisition system
• the four-tracking of Filton Bank (and associated signalling infrastructure) to facilitate capacity improvements between Dr Day’s Junction and Filton.
