In addition, the weight of the trains traction increasing, the rate of increase in installed and used as a freight train on the coupler, 13,16,17, 13 coupler as a result of the use of long hours, 16, 17, a new coupler for the coupler, so the problems Also exposed the growing significantly, resulting in broken coupler and the separation of train accidents have become accident-prone. If the train separation took place in train or start running trains on the way when the delay constitutes a normal traffic accident, occurred at the ramp of the lot, especially in high-slope areas once the train air brake failure, but also part of the vehicle easily slip into the station Or slip into the interval, resulting in a collision, conflict and the derailment of a serious nature, such as subversion traffic accident. Due to the high incidence of accidents, transport and interfere with the order of the economic losses caused by more serious and should pay attention to and actively prevent them. This article from the train coupler and the separation of the common characteristics of the fault, why, as well as measures to prevent and deal with emergency in areas such as described .
