A total of 53 of these remanufactured locomotives were built from April of 1978 to 1981. The first prototype unit of this model was IC #8701 and the rest of the series were numbered between 8701 and 8753. IC units 8701 through 8726 were built in 1979 while units 8727 through 8750 were built in 1980; the remaining three from 8751 to 8753 were built in early 1981.

Core units for the rebuilds came from IC GP9 and GP18, MBTA GP9, RDG GP7 and UP GP7, GP9 and GP9B.

In the Spring of 1979 the Clinchfield Railroad sent six GP7s to Paducah to be rebuilt to GP11s. These units were called GP16s by Clinchfield.
