The paper introduces the conclusions of lifetime research of the locomotives at Saigon Locomotive Enterprise (SGLE) in Vietnam. This research bases on reliability theory to define the gamma-percent lifetime of locomotive. The authors build the CT2010 spreadsheet for empirical statistical data process of the locomotives. CT2010 can rapidly calculate the gamma-percent lifetime and define the suitability of seven probability distributions including exponential, normal, gamma, lognormal, Weibull, Rayleigh, and Maxwell distribution.
