Thameslink High Capacity Infrastructure System


The implementation of the Thameslink Programme was carefully phased to ensure that a reliable service was maintained as the new signalling and control system was introduced, with Siemens and Network Rail working in close collaboration to deliver the High Capacity Infrastructure (HCI) programme.

The HCI programme provides the European Train Control System (ETCS) and enhanced signalling control systems needed to support automatic train operation (ATO) and timetable management, these systems being critical to the programme being able to reliably achieve the required 24 train per hour operation.

The introduction of this system means that when deployed across the Thameslink core and London Bridge areas, all train movements are controlled automatically from Network Rail’s new Three Bridges Rail Operating Centre, with every train running at the optimised speed profile and intervals, performing accurate stopping, and maintaining a strict adherence to station dwell times.
