Abstract
An improved drawbar connection for railroad cars reduces slack between cars and results in improved train handling. The drawbar connection fits in a standard draft gear pocket and utilizes a standard yoke, standard follower and standard coupler pin, thereby permitting the application of drawbars with minimal structural modification to cars originally equipped with conventional couplers. The usual draft gear is replaced by a filler which is relatively rigid. The filler includes a follower block, a wedge, a filler block and may include a mini-draft gear having a maximum travel of about one-half inch.
