A suggestion for the post resignalling stretch of London commuter line. BR blue slam door EMUs and some DEMUs following all 3 lines from Dartford up to London. via sidcup Via bexleyheath Via woolwich none of the lines themselves are longer than 18 miles but throw in the old chord from Charing x to cannon st and the depots at hither green and slade green and you have huge numbers of services running a number of diagrams with a limited number of locos. Throw in a couple of br blue 33s and you have the ballast trains from hoo (off map) and lewisham.
Strange , I rode on this route today for the first time in 3 years ! I would like this , preferably in modern day though
I'd expect the slam door EMU's to make an appearance on the BML, so would hope that a good old fashioned Network South-east route pre 1994 is some where in the pipeline.
