The London MB and SM Buses - A London Bus Disappointment

A critical examination of London Transport's ill-fated MB and SM buses, which failed to meet expectations and ended an era.

PURCHASED to replace London Transport's ageing RT-type fleet, and also to ease staff shortages by extending one-man operation, the MB-types were not only a disappointment, but an unmitigated disaster! Their successors, the SM-types, were if anything worse, being underpowered as well as equally unsuitable for London operation.

In this new volume of his photos, Jim Blake takes a critical look at what were therefore some of the most unsuccessful buses ever operated by London Transport, operating only between 1966 and 1981, most of them however achieving only six or seven years' service - if that.

Most of the pictures featured have never been published before and many show rare and unusual scenes, several inside LT's garages and Aldenham Works, now themselves no longer in existence. In addition to the buses themselves, Jim also catches glimpses of London life spanning the period from the "swinging 'sixties" to the harsh first years of the Thatcher regime.

The MB and SM family of vehicles also saw service with London Country, the latter being delivered new to them - but they fared just as badly in the outlying countryside around London as in Central London. They brought to a sad end London Transport's long association with A.E.C. buses, and could not have been more different from the legendary, long-lived RT, RF and Routemaster classes produced by that manufacturer!

Jim Blake was born at the end of 1947, and he soon developed a passionate interest in railways, buses and trolleybuses. In 1965, he bought a colour cine-camera, with which he captured what is now very rare footage of long-lost buses, trolleybuses and steam locomotives. These transport photographs have been published in various books and magazines. Jim also started the North London Transport Society and, in conjunction with the group, he has compiled and published a number of books on the subject since 1977, featuring many of the 100,000 or so transport photographs he has taken over the years.
