What can cab signalling ever do for us?

Event Type

Technical Paper


Paper to be presented by Bob Barnard


Apart from the Cambrian pilot, current ERTMS schemes in Britain are overlays on existing lineside signalling, implemented to increase the performance of certain fitted train fleets. Meanwhile proponents of ERTMS say we must move to Level 2 or Level 3 without signals. Do we properly understand the nature of the benefits that can be obtained by removing the lineside signals? Bob Barnard has worked on a variety of train protection and cab signalling schemes over 40 years - from coded track circuits to ERTMS. In this interactive talk, he will sketch the historical background and give some views on what cab signalling (whether ERTMS or other systems) can or can’t do for main line railways. The aim of this is to dispel some common misunderstandings, and to provoke discussion about the benefits and limitations of moving away from reliance on lineside signals..
