As part of Crossrail’s £50m upgrade for Ilford Depot, TICS (via VolkerFitzpatrick Limited) was awarded the Design, Installation, Test and Commissioning of the Signalling Systems.
The Ilford Depot provides stabling for up to 12 trains from Crossrail rolling stock along the north-eastern section of the Crossrail network.
The main works included:

- Infrastructure upgrades, utilities connections and provision of traction power throughout via 25kV overhead lines.
The Ilford Depot
The works were carried out in six stages with TICS construction works in Stage 1 and Stage 6.
Stage 1 was split into two – Stage 1b was a minor alteration to two signals and Stage 1e was incorporation of the paint shop depot protection interface requirement with the existing signalling.
Stage 6 was carried out during a 3 ½ month blockade followed by a further 5 month of a PC Boundary environment to allow installation, pre-testing to be completed with the final commissioning undertaken during a single stage possession arrangement at the beginning of May 2017.
The main works consisted of new signal control and decommissioning of existing depot control, this included the following:
- New Route Relay Interlocking for the control of the new Crossrail stabling sidings within Ilford Yard Depot

All works with the exception of LB Foster for the Panel installation were all carried out using our in house TICS Design, Installation and Testing resources, coupled with dedicated project manager this project has been a labour of love for many many years.
With a value in excess of £5m, this is quite an achievement for a specialist organisation like TICS.
