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.

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.
