During its 5-year construction, Crossrail (OOCPA Project) focused on the remodelling of Old Oak Common to Paddington station, which is approximately 2 miles of track. Over the course of the project 50+ point-ends were installed as well as the relocation and installation of new and existing signals and track circuit upgrades alongside the construction of overhead lines.


RSSI’s Signalling division worked alongside Carillion primarily supporting their P-WAY and Civils teams carrying out the modernisation of the track infrastructure, through the supply of SMTHs, Points Fitters and installers.
The nature of the works meant that the Signalling department’s resource team needed to constantly adapt to the changing roster, as this would affect both the numbers of staff as well as their competencies required. The company maintained a recruitment and training programme that continually met the demands of the work schedule as well as sustain the high-level service the organisation is renowned for. This meant that RSSI were able to deliver a consistent workforce which helped to ensure that any issues on site were dealt with quickly and also the consistent involvement in the planning ensured the recruitment and training aligned with the project workloads, particularly for demanding S&C commissioning weekends.

Furthermore, due to the length of the project and the continual introduction of new assets, RSSI worked inherently with Network Rail (NWR) Delivery Units offering assistance to faulting and maintenance teams.


The RSS ethos has always been to not only supply the labour but to focus on communication, planning, competence and experience. The success of this project demonstrated that this attention to detail was a determining factor in delivering the exact resource capabilities required resulting in a project that was presented on time and to budget.
