Title: Signals on the end of platform - and need these days? Post by: grahame on April 18, 2015, 20:49:11 I'm very used to seeing signals on the ends of platforms - indeed I can't recall any station that didn't have then in my youth. But I suspect that even in those days they were there for historic reasons to some extent - that's were the operating blocks were, and it was useful to leave it that way because a fast passenger train could pull up behind a slower loose coupled freight, and perform its station duties while waiting for the line to clear.
But, these days, is there any such requirement - to maintain signals on the end of established platforms, or indeed to add signals at the platorm end should a new station be built in the middle of a double tracked section?

Excellent - good to have it confirmed. This page is printed from the "Coffee Shop" forum at http://gwr.passenger.chat which is provided by a customer of Great Western Railway.
