Thanks. I'd always just assumed the police station/Waitrose site was former sidings as it seemed the right shape and position!
Interesting about the loss of Tesco and Safeway when the RBS building went up. Bromley is very poorly served by supermarkets compared to Kingston/Croydon/Sutton etc.
The northernmost part of the car park is where the old goods yard was - it was long and thin (unlike than Beckenham Junction - see upthread!).
The area north of Masons Hill and west of Kentish Way was - according to the only map I can quickly find online - a backstreet area, which accords with my recollections (but I can't remember the detail).
There's simply no room near Bromley town centre for more supermarkets
