When a new high-speed railway(HSR)is planned,one of the most important elements to consider in decision making is the economic and social balance of the system.For this purpose,the life cycle cost(LCC)of the principal components is essential.Obviously,the extension of the life cycle for each element is a clear indicator of the total LCC and,in the case of rolling stock。
When a new high-speed railway （HSR） is planned, one of the most important elements to consider in decision making is the economic and social balance of the system. For this purpose, the life cycle cost （LCC） of the principal components is essential. Ob- viously, the extension of the life cycle for each element is a clear indicator of the total LCC and, in the case of rolling stock, this extension depends on many different factors： type of trains, type of components, type of operation, infrastructure, kind of mainte- nance and its cost, technology evolution, and so forth.
