SelTrac System
Implementation

Background

As part of London Underground’s investment to increase network capacity and reduce journey times, a new, state-of-the-art signalling system is being installed on the Jubilee and Northern Lines.

Thanks to our growing reputation for technical competence and high quality delivery,  Kelly Rail secured a contract to work with Thales Rail Signalling Solutions to install the new signalling system.

Scope of Work

The project required the installation of the new TBTC SelTrac signal system; including all signal and    electrical equipment used in the Signal Equipment Rooms and on the trackside. It also included the interfaces with existing point mechanisms.

The signalling services included SER signal wiring, signal correlation, 7pr and 3pr concentric cables, 10c, 6c, 4c and 2c multi-core cables, RG22, C23, C28 and Cat5 cables, 2c multi-core telecom cable and       concentric and multi-core cables.

The electrical services involved LV power installation, testing and commissioning which included containment, brackets, low voltage equipment and wiring systems, uni-strut and brackets to accommodate the electrical cables wiring to design of isolation switches, power distribution boards, uninterrupted power supplies, bypass switches and transformers, steel wired armoured (SWA) and LSF PVC cables, SEB and associated cabling.

Key success factors and innovations
