OK I have been thinking on this, day accurate modelling is out, no way could I do it, for a start I never spotted one place for a whole day.
Month?
Year?
I cannot get my interests lower than 6 years, so my railway will be for 6 years range, covering the important for me.
Early spotting days and seeing PWM650 fresh from repaint (yes I am building it), an Eastern region aircon set heading to South Wales. Blue Met Camm 101s, Leander on railtours.
Then 50 refurb and 28th November 1981 railtours (I have 22 just because Lima made it).
Then my main spotting era through the early 80s. Peaks 50s 47s ect
Ending up with GWR150 got 34666 4575 4406 on the kitchen table, all Triang based cut and shut TSOs with Replica glazing.
Hence Also need Dumbleton Hall, and the above Castles.
Area trying to cover Gloucester Cheltenham Stroud valley area, so thinking of keeping a station open which shut between Worcester and Cheltenham.
