The existing Railway Train Shunters are generally mobilized by driven wheels. This arrangement has a limited tractive force. The size of the tractive force developed by driven wheels is a function of the own weight of the shunter. That is why for heavy train is necessary to use few shunters at the time. The effect of slipping wheels limits the maximum tractive force that is able to develop a shunter or set of shunters. Modern technology knows cases when pulling or pushing of the train is done by using set of the clamps on the each rail by turn. The system is actually repeating the nature where a monkey by gripping of the branches moves upward. This system based on the gripping clamps has much higher tractive force in comparison to driven wheels but is very limited in terms of the speed and doesn't allow any continuous grip on the same rail. The continuity of the grip in this existing case is based on the very short overlap of the grip on both rails at the time during shifting of the gripping from rail to rail. The effect of the shifting a gripping from rail to rail and return motion of the clamping set makes the existing system very complicated with huge mechanical and hydraulic difficulties and limitations. The new invention based on the crawling chain with clamps as it shown on the fig.1 used to overcome the above mentioned problems and limitations.
