The approach, data, methods, and results of a detailed disaggregate life-cycle costing analysis of transit vehicle operation at the Hamilton Street Railway (HSR) in Hamilton, Ontario, are summarized. The life-cycle costing was performed in 1991 as part of an overall study of future technology, which included particulate-trap-equipped diesel, compressed natural gas, and electric trolley buses. The study used the HSR's detailed maintenance, fuel, mileage, and other records to obtain base diesel lifetime costs. A combination of internal records and those from manufacturers and other operators were used to forecast lifetime costs of the new technologies. Pollution, noise, transit planning, and other such aspects included in the overall study are not discussed. This analysis indicates that an all-natural-gas fleet would be the least expensive to operate in the long term, with an all-diesel fleet second most economical. |
