How many toasters have come and gone; without ever reaching the service life of the GG1?
I'll be a fan of the GG1 for life but the AEM7s proved very successful in service. Considering Amtrak GG1s were mostly later production from 1942-1943 and served until 1981, they have an average life of 39 years in continuous passenger service. The AEM7s entered service in 1980 and ran until 2016 so they had a service life that was nearly as long. AEM7s also held down faster trains pulling Metroliners at 125 mph while GG1s were limited to 100 mph operation and generally didn't operate over 90 in corridor service under Amtrak. PRR/PC rarely operated the Gs over 90.
The Conrail ones being lower numbered certainly had longer and harder service lives doing freight duties which the GG1 was not designed for. 4800 operated the longest at 45 years and ran about 5 million miles. A very enviable service record but the AEM7s certainly earned my respect and were well liked by the Amtrak crews that operated them.
The ALP-44 shouldn't be confused with the AEM7. ASEA provided the design that EMD built under contract and Budd supplied the bodies and were based on the Rc4 prototype. All around a very successful partnership. The ALP-44 was built by ABB, based on the European Rc6 and limited to 100 mph operation. It did not prove to be as successful in commuter service as NJT had hoped, however I have never fully understood why NJT chose to retire these so soon and replace them with the ALP-46. They were not poor performers.
I posted this image the day the Toasters were original retired in 2016.
For any that I may have caused some heart palpitations to for saying the AEM7 was a worthy successor to the GG1, here is an antidote
Finally, for comparison's sake a most unworthy successor to any electric locomotive in the Bombardier HHP-8. They were not reliable, rode poorly, and are now being tested for possible use as cab control units after a very short service life.
