The motor truck is entirely built of steel, and as stated before,has 8 ft. wheel base; the wheels are 3 ft. 6 in. diameter. Theweight of the car is transmitted from the top bolster by meansof elliptical springs to the swing bolster, the weight being trans-mitted thence in the usual method by swing links to the truckside frame. Steel angles from the side frames, cast-steel stifl-eners riveted to the outsides of these form nests for the topsof the heavy helical springs, which intervene between the truckframe and the straight equalizer bar. This equalizer bar iscarried in stirrups below the axle boxes, the stirrups themselves.

A special feature in connection with the axle-boxes is that the fillets on the journals are kept quite clear ofthe brasses, thus avoiding a fruitful source of hot gears are solid and trussed, to the axleand keyed. The current, as already stated, is col-lected by cast-steel shoes on each side of themotor truck. These shoes weigh about 90lbs. each, and have so far given the great-est satisfaction. On straight runs of thirdrail, there are thus four shoes collecting atone time. From these shoes, which aresuspended by forged slotted links from awooden beam carried on extensions on thetruck, a highly flexible lead of special con-struction is carried to a fixed terminal,from which the main cables pass to thecontroller. The vacuum brake is used on the trains,thus making them adaptable for servicewith the companys other rolling stock andlo
