Abstract
A tank car recovery system utilizes a lifting bar that attaches at two points to the tank car by lifting points. The lifting bar is raised by hoists attached at either side. Rigging is connected to the hoists and the lifting bar. Rigging is also used to attach the lifting bar to the tank car. The hoists are operated separately to adjust the position or rate of movement of each side of the tank car.
