The entire underfranic is covered with 5 plates on which the floor is laid. The floor is of lyi-in. tongued and grooved yellow pine material. The truck is of the Buckeye pedestal type for 3-ft. 3J^-in. track gage and has a wheel base of 4 ft. 9 in. Thewheels are steel tired on cast iron centers and are 27 in. indiameter.

The direct actionof the two springs is secured by an ingenious arrangementof sleeve and spool, which carries the reaction of eachspring directly from one follower plate to the other. The for-ward spring is slipped over a spool, the rear end of whichbears against the forward end of the rear spring, thus carrvingthe forward reaction of the rear spring directly against theforward follower plate. The backward reaction of the for-ward spring is similarly carried to the rear follower plate bymeans of a spool which encircles the rear spring. The body is made up of by oJSin. by 34-in- anglecomer posts, channel section door posts of J-4-in. pressed steeland four special flanged U-section intermediate posts on eachside of the car.
