Abstract
A rail train for supporting multiple sticks of ribbon rail comprises a plurality of rail support cars having a single, centrally positioned rail support stand wherein adjacent rail support cars are supported on shared trucks. End cars include a tunnel for supporting the rails near their ends and one or more rail support arms pivotal at a first end about two axis and supporting a rail guide assembly at a second end for supporting a rail as it is pulled of the rail train. A rail tie-down car utilizes spring-loaded, hydraulically actuated clamp assemblies to clamp individual rails to the tie-down car. Each clamp assembly incorporates at least two clamp members which act opposite one another to prevent the rail secured in place by the clamps from sliding in either longitudinal direction.
