Abstract
A schnabel-type railroad car adapted to carry very large loads incorporating articulated end units having a massive hinge at a reduced pivot location so that the weight of the car can be carried at a central location on the trucks while still pivoting about a lesser radius to help negotiate tight turns. Special hydraulic systems permit the car to be raised and lowered and also shifted laterally to provide additional roadbed clearance.
