A diesel could replace about 10 steam locomotives. F. Fewer fuel and water stops. A diesel requires little water. A low center of gravity enables higher train speeds on curves. Unlike steam locomotives, diesels do not stress the track with the pounding force of reciprocating components.
Track maintenance is reduced as a result.
Since diesel locomotives were standardized, they made good collateral on bank loans. This meant that railroads could borrow money easier and upgrade to diesels even if the financial condition of the road was not good. The average steamer after World War II was 20 years old and out of date. The rising cost of coal and inability to find spare parts also hastened the demise of the steam locomotive. The Baltimore and Ohio Railroad provides a good example.
