Well this has always been a tricky issue, why? well I cant make my mind up!! I have a few pet scenarios spread over 4 timeframes all GWR or BR(W)
Paddington C1906, well something round the back anyway, Bishops road or the goods depot Paddington C1970 similar scenario to the above but with all those lovely hydraulics and parcels stock Winchester C 1930 Didcot Newbury and Southampton Rly, half the station not including the goods yard Winchester C 1948 but with Q1's and T9's as well as an ancient Duke Ashburton 30's the quintessential GWR branch terminus
(Un)fortunately I have items of rolling stock to cover all of the timeframes!? one of the problems is the long time frame for a 7mm project, and coupled with my short attention span it makes for 'strategic drift'. I flit from one to another as the mood takes me but I really do need to nail it down other wise I am just going to end up doing nothing.
Still on the bright side the S7 GE mafia hasn't got to me, I can't be bought, unlike some eh, JB
