HC Deb 14 January 1977 vol 923 c617W
Mr. Spriggs

asked the Secretary of State for Transport how many private sidings would be required to accommodate 50 per cent. of the heaviest road haulage lorries or wagon loads.

Mr. Horam

It is not possible to estimate the number of private sidings required. The number would depend on such factors as the origin, destination, timing and nature of the traffic.
