Would this be better in Gen?
I'm no expert but there's regularly a FL 66 doing shunting in *forgot the name* the sidings next to the mainline up through the avoiding line and onto the carriage reception sidings,
it's hard to see from the station.
I visited in 2005 and during maybe a 1 hour stay there was a EWS 66 on coal duties, a light FL 66 and a EWS 60 all passing through.
When I went to York IECC with NR the way you access it would be a brilliant vantage point for photters as it practically runs with the avoiding line and the mainline is also visible...
