The rear truck is of the Rushton type, with inside journals,In this design the truck swing links are pinned to a pair ofyokes which constitute part of the equalization system, the yokesbeing prevented from moving laterally by the truck pedestals on each side are fitted with renewable wearingplates 3/16 in. thick. There is no cross-connection in the driv-ing equalization system, as the driving and truck journals arein line and the equalizers between the rear drivers and. Boiler of the Richmond, Fredericksburg & Potomac Locomotive of the solid plate. A complete installation of flexible stay boltsis used, and the front end of the firebox crown is supported bythree rows of Baldwin expansion stays. The firebox is carriedon expansion plates at the front and back, and the boiler barrelis supported by waist sheets at three intermediate points. ASecurity sectional arch, a 40-element Schmidt superheater and aChambers throttle valve are included in the boiler equipment. the trailer are connected directly with the spring arrangement of the running-boards and hand-rails is sug-gestive of the practice followed in certain parts of ContinentalEurope. The hand rails are placed outside the running-boards, the total width over the latter being 10 ft. 3 in.,and a flight of steps leads from the running-boards tothe front bumper.
