Once operating trains are disabled on the railway lines,an efficient manner is to utilize the train for train *** to the different train and coupler types,it is difficult to formulate uniform regulations for train to train *** this paper,the longitudinal train dynamics of electric multiple units under rescue were analyzed by field and laboratory *** angling behavior of the brakinginduced coupler under compressed in-train forces was analyzed.A dynamic model for the train and draft gear system was developed considering accurate boundary limitations and braking *** safety indices and their limits for the coupled rescue train were *** evaluations of different train to train rescue scenarios were *** is indicated that the coupler vertical rotation occurs during the emergency braking applied by the assisting *** vertical force components of intrain forces lead to the carbody pitch behavior and even cause local destructions to the coupler *** carbody pitch motion can arise the inference of in-train *** on the safety evaluation of train and coupler system,the regulations for typical train to train rescue scenarios were formulated.
