Heathrow Central Underground station (now Heathrow Terminals 1,2,3). View of the platform. An illuminated station name roundel is fixed to the wall foreground right. In the distance, an illuminated direction sign with pictograms can be seen. Advertisements line the tunnel wall on the left. This photograph was probably taken prior to the opening of the station on 16 December 1977 - note the bare wires in the trunking in the frieze.
