Starting at the Cox's Walk footbridge, we then embark on a short but enjoyable ride along the Crystal Palace High Level branch using rare archive film taken from the last passenger train in September 1954. Remaining in south London we look at remains of the long-closed stations at Waterloo Necropolis, Grosvenor Road, Battersea Park Road, Camberwell New Road, Southwark Park, Spa Road and Blackfriars SER. Beside the former entrance to Blackfriars we see stone name-panels where remnants of incised lettering continue to display part of the station's name and that of its original company. Remarkable survivals indeed, particularly when one considers that the last train called at the end of 1868. Moving to East London we visit the one-time 'Commercial Street Office' at Bishopsgate Low Level with its eerie subterranean passageways. Like a number of inner-suburban stations, Bishopsgate closed during the First World War and never re-opened. Continuing with the subterranean theme, we encounter some abandoned stations on the Underground network, including York Road, Down Street and Brompton Road. Although screened from passing trains for many years, much of the original platform-level tilting at Brompton Road remains in good condition, even some of the name panels. The views featured in the programme were filmed during a special visit organised for the London Railway Record editorial team back in 1997, whilst research was being carried out in connection with the best selling book 'London's Disused Underground Stations'.
