We were asked to develop a communication-based train control (CBTC) system. These are part of a new generation of signalling technology, and we were able to push this further in an innovation that worked – for the very first time – for heavy haul rail.
The customer required a centralised system that met CENELEC EN 50128 standards, as well as SIL 4 – the highest possible safety standard.
We assembled dedicated teams, which focussed on rigorous software development and testing. The work had to be engineered to integrate with existing rail infrastructure systems and had to be tested at all levels in both a simulated situation and out on track.
We worked hand-in-hand with the customer at all stages to deliver a solution which met those rigorous standards, while ensuring the system provided a solution that worked both in theory and in practice.
