Thanks, Paul. Yes, it does sound like a good place to see trains! I
didn't know there were marshalling yards at Hither Green, I shall have
to investigate....

There's nothing significant there now. There is an engineers yard adjacent
to the depot, in the triangle between the Orpington lines and the Lee lines.
Most of the former yards on both the up and down side of the Orpington lines
are now used for stabling electric units.
