§ 70. Mr. WILMOT
asked the Minister of Transport what is the approximate total capital cost of converting the existing track voltage of 750 volts third-rail system, using the most modern methods of mercury-arc rectification, on all the existing electric railways in the London and suburban area of the London Passenger Transport Board and the London Midland and Scottish and the Great Western Railways; in what period of time could such a conversion be completed; and what reduction of operating cost could be effected?
§ Captain A. HUDSON
If the hon. Member will furnish me with more precise information as to the nature of the alterations he has in mind, I will ask the London Passenger Transport Board and the railway companies whether they are in a position to furnish the information he desires.
