GE did the same with USA diesel railway locomotives, starting from scratch in the early 1960s, knocking out the long-established No 2 in the market in about 10 years, and eventually overhauling General Motors, who had been the market leader since such machines first appeared in the 1930s.
The surprising thing about the Aero engine market is not how GE did so well, as much as how Pratts lost it.
