JIM BLAKE's second volume of his photographs featuring the London Underground cover the period from 1985, shortly after the Thatcher regime's destruction of London Transport and its re-birth as London Underground Ltd., to 2021 when the Northern Line gained its new branch from Kennington to Battersea Power Station.

This was a turbulent time in the system's history, encompassing the withdrawal of the last pre-war passenger rolling stock (in 1988) and then the abolition of two-person operated trains at the beginning of 2000.

With the exception of the Waterloo & City Line, which was transferred from British Rail to London Underground in the 1990s, all Underground lines are covered together with the rolling stock operating them.

Jim's photographs concentrate on the older types. What is very striking in them is how the system seemed to be going downhill rapidly during the Thatcher years when this survey begins - plagued by the curse of graffiti and liberally littered thanks to cuts in staff who once dealt with such problems. Fortunately, since Transport for London's takeover of the Underground from 2000 onwards, things in that respect have markedly improved, trains and stations are much cleaner and therefore welcoming to passengers.

The contrast between the late 1980s/early 1990s and today's Underground is very clear in Jim's photographs featured here, most previously unpublished. It is unfortunate that further improvements, not to mention long-planned extensions to the system, continue to be frustrated by government spending restrictions at the time of writing.
