A jumping rail to be positioned within a trackway having a base, a platform defining a path and mounted to pivot with respect to the base between a first position wherein the platform is aligned with the base to permit a vehicle after passing over the platform to continue travelling along the trackway and a second position wherein the platform is raised upwardly from the base causing the vehicle to jump, a mechanism for normally urging the platform to its second position, a striking member extending from the base upwardly through part of the path defined by the platform and mounted to move between a first position wherein the striking member engages the platform retaining the platform in its first position and a second position wherein the striking member disengages from the platform permitting the platform to move to its second position, and an additional retaining mechanism for rendering the striking member inoperable so as to continuously retain the platform in its first position.
A jumping rail, comprising a base having an upper surface, a platform having an upper surface, means mounting said platform to said base to move between a first position wherein said platform upper surface is aligned with said base upper surface and a second position wherein one end of said platform is raised upwardly from said base, means urging said platform to said second position, a striking member projecting upwardly from said base beyond said upper surfaces, means mounting said striking member to said base to move between a first position wherein said striking member engages said platform retaining said platform in its first position and a second position wherein said striking member is disengaged from said platform permitting said platform to move to its second position, means urging said striking member to its first position, and releasable means maintaining said platform in its first position regardless of the position of said striking member.
