§ Sir Knox Cunningham
asked the Minister of Aviation what was the cost of installing a single direction escalator from the ground floor to the first floor passenger exit in that part of the terminal building at London Airport reserved for United Kingdom passenger services; whether the operating cost of £1,200 for such a unit includes any sum for repayment of capital; and whether the cost of £1,200 is an annual cost.
§ Mr. Marten
I regret it is not possible to segregate from the total cost of the building, the cost of installing one escalator. It was installed when the building was originally erected. The annual operating cost of about £1,200, given in reply to the hon. Member for Wembley, South (Sir R. Russell) on 12th December, 1963,included interest and depreciation on the capital cost of the equipment.
