The ends of the transverse barsrest on the bottom flanges of the track rails and the longi-tudinal bars rest on two 4-in. x 3-in. x 5/16-in. angles con-necting the tops of the rail-supporting posts. The stairwaysat the ends of the pits are of cast iron with 9-in. treadsand 9-in. risers. Each track opening at the ends of the carhouse is fitted with a hand-operated Kinnear rolling steeldoor, and all openings from bay to bay through the curtainwalls are fitted with two automatic sliding fire doors con-trolled by fusible links.
