Motor Road Transport For Commercial Purposes
(Liquid Fuel, Steam, Electricity)

84 MOTOR ROAD TRANSPORT wages figure of £115 14s. Ild. may be arrived at by dividing the Capital charges by the total mileage, adding the driving, tyre and current costs, and subtracting this total from 7'Ild. The complete analysis will be as follows— Cost per Capital charges, Insurance, and driver’s Mile. licences . . . . . 2-85d. Driver’s Wages ..... 2-17d. Maintenance of vehicle and battery, including lubricants (material 0-57d., labour 0'48d.) l-05d. Current ....... 0-54d. Tyres ....... 0-50d. 7-lld. These figures are based on interest at 4| per cent., and current at 0'5d. per unit. If, however, as an alternative, 5 per cent, for interest and ld. per unit for current be taken, the cost per mile will be 7-73d., a figure which, at the time these tables were drawn up, compared favourably with the cost of petrol vehicles. The latter figure of 7-73d. is based on annual Capital charges amounting to £127 16s. 7d., which, including as it does £10 for Insurance and lOs. for driver’s licences, is equal to 17-4 per cent, of the cost of the vehicle, as regards interest and repayment charges. At 4| per cent, interest, the percentage of the purchase price is 16 86. All cleaning, overhauling and repairing was done as a rule on Saturday afternoons, and occasionally at night and on Sundays. The consequent overtime naturally increased the maintenance costs. Another Municipal Example. In another case of the electric vehicle working on municipal work, a saving over horse haulage amounting
