HC Deb 13 May 1959 vol 605 c136W
19. Mr. D. Griffiths

asked the Minister of Transport and Civil Aviation his estimate of the comparative maintenance costs of a diesel engine and a steam engine of comparable motive power.

Mr. Nugent

The British Transport Commission estimates from the limited experience of main line diesel operation so far, that the cost per engine mile of maintaining a diesel locomotive seems likely to be at least 20 per cent. less than for a steam locomotive of comparable power.
