We see Liverpool Street station before the rebuilding, carried out between 1986 and 1992, when long distance services, parcels and freight traffic, were diesel hauled by class 31, 37 and 47 locos.
Stratford has always been a busy place to observe freight workings, many of which were in the hands of class 37 locos.
The LNER desined class 306 Shenfield units are extensively covered, along with the classes 302, 305, 307, 309, 312, 315, 321 and 322 EMU's amongst others.
DMU workings from Camden Road to North Woolwich are featured.
Much o the programme was filmed with sound, and the distinctive noises of the Shenfield units are well captured.
Later scenes show the preserved green unit 017 in passenger service in 2001, alongside Great Eastern branded class 315's.
Also featured are class 86 and 90 electric locos, the Stansted Express, Electrostar, Desiro and class 170 turbo units.
