Vertex have assisted Network Rail in gaining a second Railway Safety Regulations 1999 (RSR 1999) exemption caused by the introduction of non-ATP trains in the Paddington-Airport Jn area. This exemption became necessary due to the anticipated delay in commissioning ETCS train protection in this area and the introduction of Crossrail and other stock lacking 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 ORR.
Vertex had previously supported NR in gaining an acceptance for enhanced TPWS as a mitigation for loss of GW-ATP train protection in the same area.
November 2018 – March 2019
Vertex utilised its team of Railway Systems and Safety Engineers and Project Managers for this project. Combined rail experience of the team exceeded 60 years (3 persons) and included those who had worked on the previous RSR 1999 exemption in 2014.
