HC Deb 06 February 1930 vol 234 c2094W
Mr. KELLY

asked the Postmaster-General the amount of work engaged upon by his Department during 1929 for the purpose of transferring overhead lines to underground?

Mr. LEES-SMITH

About 470,000 miles of wire in underground cables were provided during 1929, at a cost of about £3,900,000, of which about 10 per cent. were in substitution of pre-existing overhead wires, while the balance represents increased capacity.
