Double Track Swing Bridge

The Walthers Cornerstone Double Track Swing Bridge is based on prototypes built to cross broad rivers, busy harbor entrances and other navigable bodies of water. In use from the 1900s to the present, this model has sufficient clearance for use with virtually any loco or cars, as well as modern double-stack equipment. Like the prototypes, the model is designed to be turned 90 degrees by hand in a single direction. A final drive gear and micro switches are provided to convert the model into a powered bridge with the Universal Gearbox and Motor Drive Kit 933-1050, sold separately. This unit is fully assembled and designed for drop-in mounting with the bridge kit. This model also matches the track spacing of Cornerstone double-track bridges, so several could be used to model approach bridges. (Typically, only one moving bridge is used in prototype situations). Double-track abutments and wing walls can also be used to detail the approach bridges and make the scene more realistic. To prevent derailments on the span, bridges are fitted with special track sections, equipped with an inside guardrail. This detail can easily be added to your model with Walthers Code 83 Bridge Track (948-899 with "V" end guard rails used at each end of the bridge; for a longer span with approach bridges, 948-886 with no end guard rails can be used), which features code 70 inside rails.
