Hornsey Depot - Signalling


VolkerRail, on behalf of Siemens, installed and commissioned a fully integrated and interlocked depot signalling system at the newly developed train care depot, in Hornsey.

The depot’s new signalling system replaced the existing hand-worked points with a fully interlocked route relay interlocking signalling system; fully integrated with an innovative depot personnel protection system (DPPS). These newly installed systems operate from a new NX panel, located in the depot’s newly purpose built signalling Control Centre.

The depot’s new signalling system consists of

  • 45,000m of line-side cabling
  • 31 locations cases
  • relocatable equipment buildings
  • 72 signals and 60 motorised points each fitted with an innovative hand mechanism.

The depot’s new interlocking system consists of 2,200 relays and 33,000 wire runs, totalling 155,000m in length.

The new depot, currently under construction by VolkerRail’s sister company, VolkerFitzpatrick, also benefits from increased stabling capacity, new roads equipped with controlled emission toilet facilities, a new maintenance facility building and two train-washes. The new train washes use reclaimed water from the washing cycle plus rain water harvested from roof drainage to reduce environmental impact and minimise the use of mains water.

Hornsey traincare facility is part of Siemens’ wider investment in the UK through the Thameslink Programme. The upgraded facilities at the Hornsey depot will enable more trains to be maintained and serviced to meet the increase in passenger demand in the south east.

"These latest upgrades mark a major milestone in the Hornsey Depot project, part of the wider Thameslink Programme. We are delighted that the work will help to increase the depot’s operational efficiency and safety. I congratulate the delivery team on meeting the challenge and thank them for their continued dedication and effort."

Simon Linnemans, Hornsey project director for Siemens
