Hi all, probably one of the UK experts can answer why in UK bidirectional signalling, also on main train routes, seems to be rather occasionally implemented. It came to my mind while using the busy Doncaster simulation where no bidirectional signalling for the main London to York line exists. Is it because of security reasons? Or cost implications? How is the train traffic organized when reconstruction work in a train section starts? There I assume a bidirectional signalling could ease maintaining (limited) train traffic using the second (parallel) track. In Austria and Switzerland bidir signals are usual, in Germany where I live also quite often. Simply interested in understanding the difference! Thanks a lot, Cheers Ignacio Log in to reply |

Two common reasons: cost of installing and maintaining equipment which should rarely be used; and because capacity is so much lower that you're going to have to run buses or other alternate transportation anyway, so why run any train service at all? There are, of course, exceptions. Rugby's four track sections have two lines signalled in both directions, and simplified bi-directional signalling is installed in many places (often with 15 minute or worse headway; okay for Sunday services and an occasional "get out of a hole" situation, but not much more).
