First phot I am guessing taken from the
GW» Hotel bit high up for what used to be the function room so must be one of the bed rooms, overlooking platform 2/3 which are under the main roof valley, in the distance the glass building stand on what was the Goods Shed. The brick building on the left are the Paddington General Offices white wall on the building is one side of what is called the bomb gap caused in April 1941.
Second phot Platform 1a Paddington also know as the UPO (Up Parcels Office) or Griffin sidings, the ramp at the back brings you out on Bishops Bridge Road
