Abstract
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 (Ato A) are coupled to one another through couplers (Bto B), and energy absorbing structures (Sto S, Sto S) 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 (Sto S, Sto S) 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).
