ABSTRACT:
A train brake device including a chocking member dimensioned for positioning around a train wheel is disclosed. A gear assembly is secured to a rear face of the chocking member. A rail clamping assembly is positioned beneath a rail of a train track and extends upwardly through the gear assembly for engagement therewith. A pawl is secured within the gear assembly for selective engagement therewith. The main usage of the present invention is for positioning around work equipment. When in place around a train wheel, the present invention will prevent injury to train crew members by blocking and preventing the wheel from rolling. This is especially important when no cabooses are present and crew members must place flashing red lights on the rear of the train.
