It was the first so-called "second generation" EMD diesel locomotive, and was produced in response to increased competition by a new entrant, General Electric's U25B , which was released roughly at the same time as the GP30. The GP30 is easily recognizable due to its high profile and stepped cab roof, unique among American locomotives.[3] A number are still in service today in original or rebuilt form.
