The 1970s were among London Transports most troubled years. Prohibited from designing its own buses for the gruelling conditions of the capital, LT was compelled to embark upon mass orders for the broadly standard products of national manufacturers, which for one reason or another proved to be disastrous failures in the capital and were disposed of prematurely at a great loss. Despite a continuing spares shortage combined with industrial action, the old organisation kept going somehow, with the venerable RT and Routemaster families still at the forefront of operations.At the same time, the green buses of the Country Area were taken over by the National Bus Company as London Country Bus Services. Little by little, and not without problems of their own, the mostly elderly but standard inherited buses gave way to a variety of diverted orders, some successful others far from so, until by the end of the decade we could see a mostly NBC-standard fleet of one-man-operated buses in corporate leaf green.
