What is the layout of the junction for the depot access line at Lambeth North? Some places say it's north of the station and connects to the n/b tunnel via a trailing-step plate; other say that it's south of the station behind a scissors crossover. Having never been down to that part of the Bakerloo yet, I don't know what's down there or where the junction is.
Has Lambeth North ever been used during times of severe disruption to reverse the southbound service, i.e. half the trains reverse at E&C and the other half reverse at Lambeth, with lots of yelling from the driver at Waterloo?
