asked the Minister of Transport if he will give the cost per engine for the conversion from coal to oil burning; the length of time taken to carry out such conversion; and the comparative cost per engine mile of coal and oil-burning engines.

I am advised that the best estimate possible at present of the cost of conversion, including the cost of the

stion of the restoration of the Cornish Riviera express, which I trust will be at the earliest opportunity?

Will the Minister remember the very long distance of the Cornish holiday resorts from the industrial centres of the country, and that the workers from those centres need rapid means of transport to get there if the best use is to be made of the limited amount of coal which the Government are able to supply?
