Radio-Based Limited Supervision System

Date: Thursday, 17 September 2020 - 5:30pm to 7:00pm
Venue: Virtual meeting, details to be advised
Speakers: Andrew Simmons
Registration: Not Open / Closed

Twenty years on from the tragic train collision at Ladbroke Grove, the GB rail industry considered it appropriate to review the current train protection strategy to understand if it still managed SPAD and Overspeed risks so far as is reasonably practical. Whilst the review concluded that with current technologies of TPWS and ETCS Full Supervision the train protection strategy was still appropriate, further investigations were required to understand if alternative technologies could affect the strategy.  

The presentation will set-out how the GB Rail industry considered alternative technologies and how Network Rail is leading the development of a Radio Based ETCS Limited Supervision concept.
