In energy absorbing structures in an entire train, a compression amount at an interface between cars at an end portion of a train is reduced and compression at an interface between cars at a center portion of the train is facilitated. In the structure, a plurality of cars (A 1 to A 12 ) are coupled to one another through couplers (B 1 to B 11 ), and energy absorbing structures (S 12 to S 42 , S 82 to S 122 ) are provided between cars. An average compressive load corresponding to a value obtained by dividing an energy absorption amount of the energy absorbing structure by a maximum compression amount of the energy absorbing structures (S 12 to S 42 , S 82 to S 122 ) is set smaller at an interface between cars at a center portion of the train than at an interface between cars on an outer side of the train (closer to an end portion).
