HC Deb 13 February 1922 vol 150 c653W
Major GLYN

asked the Parliamentary Secretary to the Ministry of Transport whether, in the opinion of the expert advisers to that Ministry, motor-omnibus traffic is preferable in tramcar traffic in all congested cities and areas; and whether the overhead trolley system has any considerable merit in comparison with the slot system?

Mr. NEAL

The first part of the question cannot be answered without reference to local circumstances; as regards the latter part, if by "slot system" my hon. and gallant Friend means the conduit system of electric traction, the overhead system is, I understand, the cheaper in respect of cost of installation and maintenance.
