Operation of your overhead conductor rails at Shaw's Cove Railroad Bridge in Connecticut Within a movable bridge that employs a rigid overhead rail, there is a have to transition through the catenary wire procedure into an overhead conductor rail at the bridge click here portal (the last traction existing pylon prior to the movable bridge). One example is, the facility source can be carried out by way of a catenary wire program close to a swing bridge. The catenary wire usually comprises messenger wire (also called catenary wire) along with a Get in touch with wire where it meets the pantograph.
