Vertex Systems Engineering (Vertex) have assisted Network Rail (NR) in gaining a second Railway Safety Regulations 1999 (RSR 1999) exemption caused by the introduction of non-Automatic Train Protection (ATP) trains in the Paddington-Airport Junction area. This exemption became necessary due to the anticipated delay in commissioning European Train Control System (ETCS) train protection in this area and the introduction of Crossrail and other stock lacking Great Western (GW)-ATP.
Vertex have provided optioneering and qualitative assessment of options for the provision of train protection or alternative mitigations in the area and supported the wider submission of the exemption request to the Office of Rail and Road (ORR).
Vertex had previously supported NR in gaining an acceptance for enhanced Train Protection Warning System (TPWS) as a mitigation for loss of GW-ATP train protection in the same area.
Vertex resources were centrally managed to ensure efficiency in deployment as required. This was to mitigate the risk of overuse of resource within the programme.
All resource that was deployed to the project were subject matter experts and fully conversant in the programme, this prevented any delays through learning requirements.
