Operation on the overhead conductor rails at Shaw's Cove Railroad Bridge in Connecticut In the movable bridge that uses a rigid overhead rail, You will find a ought to transition in the catenary wire program into an overhead conductor rail for the bridge portal (the final traction latest pylon prior to the movable bridge). For example, the facility provide can be done via a catenary wire program in close proximity to a swing bridge. The catenary wire typically comprises messenger wire (also called catenary wire) as well as a Make contact with wire the place it satisfies the pantograph. The messenger wire is terminated within the portal, whilst the Get in touch with wire runs to the overhead conductor rail profile in the changeover close part right before it is terminated in the portal.
