Hi Lyn,could be phil as the large building is the council house...not very good with trams but is that the back of them we can see
The trams had no 'front' or 'back' and could be driven from both ends because they could not be turned round. When the tram being boarded moves off towards town, the tram on the right comes forward to just past the 'cross-over' and the driver goes to the other end of the tram and drives it across to the other track. Note the overhead line going across.
OldBrummie also explains it in his post#2718.
