Hello,
I'm nearing completion of a model of Bulleid 4-SUB unit 4749, and I have a question about which way around the two trailers go. The two motor cars have steps fitted to their inner ends, to allow access to the roof. The intermediate trailer cars only have these steps at one end each.
If I denote a Driving end as D, an inner end with steps as S and a plain inner end as P, does anyone know which of the following options is the right one?
D--------S S--------P P--------S S--------D
D--------S P--------S S--------P S--------D
D--------S P--------S P--------S S--------D
Thanks
Stuart
