At the risk of hijacking the thread, San Francisco's system is definitely interesting with the street running Breda high floor cars in the suburbs using the old street car tunnels etc.
Back to the Waddon Marsh thread, I have a Bachmann 2 EPB for a West Croydon Wimbledon project,with an E4 on pre order, need a SEF E6 for the coal trains to Croydon B. One C class allocated to Norwood Junction but did this make it onto the line on coal trains?
C2X worked the other freights but I can remember Ws on some workings to Beddington Lane sidings.
It's a great project as you can achieve much in a small area as Pete 75C has done so far.
