The trucks are of the special Beach design, maae up ofcommercial shapes, with double pedestal coil springs anddouble elliptic body springs. A 12 motor is suspendedat each inside wheel of each truck from the channel tie piece With the latter arrangement the wheel obviously slips acertain amount at cur\-es and also on tangent track becauseof the varying diameter of all car wkeels and also becauseof the coned .shape of the wheel tread. The engineers of theFederal company have made extensive experiments and claimthat if they did not rotate the wheels upon the axle or securedifferential rotation of the wheels, a car of given capacity in. Plan and Elevation of Bogie Truck—Edison-Beach System. speed and mileage range would require a battery ot at least25 per cent, greater capacity than they use at present. Thepower is transmitted from the motor to the wheel by meansof the standard pinion and gear. The car illustrated herewith is equipped with iga cells ofthe A-6 type Edison storage battery, for power, and ten cellsfor lighting. The battery is guaranteed to maintain itsoriginal capacity without deterioration or restriction as tonumber of charges or discharges obtained, and with practicallyno restrictions as to its operation, for a period of four Edison battery is a nickel-steel-alkaline cell, and it is
