Hi comrades... Just a spot of trivia, something which popped into my head earlier. What are some of the most difficult routes in the UK to work from a Guard's point of view? By difficult, I mean operationally taxing, as opposed to being a p*sshead express or assault alley. One that comes to mind is the Hereford run, where from Oxford there is an array of short platforms, of varying lengths (and on both sides of the train) in quick succession, all using SDO and on non-interlocked slam door stock (HST). What others are regarded by crews as a taxing days' work?
