Description 

The Bagby Turntable was evidently custom-built for the Yosemite Valley Railroad; it was prefabricated and assembled on-site. It is a hand-pushed railroad turntable of gallows type construction, made of heavy timbers and iron rods. The gallows is made of timbers, 16f high, and it rests on two large stringers, each consisting of four 3" x 12" bolted together. Kingpost trusses are formed by eight 1" iron rods bent over the gallows and attached to the stringers. The iron tierods are threaded for the turnbuckles and function as the tension members of the trusses. Timber crossties, bolted underneath the stringers, carry the rails. The entire carriage revolved on wheels on a single circular rail about 8' in diameter, beneath the canter. The timbers were in a deteriorated condition before the turntable was moved to El Portal, and the intention is for them to function as patterns for the restoration of the turntable.
