ABSTRACT:
A method and system are provided for opening and securing a railroad frog. The system is provided with a body member and a plurality of attachment members, which are selectively securable with the body member. The attachment members are structurally configured to secure to different structural features along spring wing rails and fixed structures positioned opposite the spring wing rail. Manual actuation of a tensioning mechanism that is coupled with the body member advances opposing first and second attachment members toward one another, moving the spring wing rail into an open position. Wedge members, coated in a non-slip material are provided as an additional means for securing the spring wing rail in an open position.
