Like all the other portions of the NEC, the newly released NEC: Washington to Baltimore Route is set in the modern era. It includes the ACS-64, the Acela Express, the MPI MP36 (Unbranded), and the P42DC and different coaches, most of which are in Phase V. While an AEM-7 (only in Phase V) is already included with the NEC: New York to Philly, I would like to send a proposal for an EMD AEM-7 Retro Pack to improvise the NEC for different eras. The Retro Pack would include the AEM-7 (with and without ditch lights) in Phase III (with a blue frame), Phase III (with a black frame), Phase IV, Phase V (without the wave logo), and Phase V (with the wave logo). Additionally, it would include Amfleet I & II coaches and a variety of Heritage Fleet coaches in Phase I, Phase II, Phase III, Phase IV, and Phase V. The locomotives shall also include new features compared to the one included with the original NEC, such as flashing ditch lights, flashing strobes, etc. Based on the Swiss SJ Rc4 electric locomotive, the EMD AEM-7's were built by Electro-Motive Division between 1978 and 1988 to replace the aging PRR GG1's and NH EP's. Originally, the GE E60's were to replace the aging locomotives, but they failed miserably at high speeds. The AEM-7's, on the other hand, proved successful at high speeds. In fact, they reached a top speed of 135 MPH! Amtrak ordered a total of 54 AEM-7's. 2 of them were wrecked and several others were damaged by fire in later years. While the AEM-7's were common on high speed regional trains, the E60's often hauled the long distance trains that used aging equipment. On occasions though, AEM-7's were seen on long distance trains until the E60's were finally retired in 2004. Up until their retirement in 2016, the AEM-7's were the workhorses of the Northeast Corridor and the Keystone Corridor. They worked the corridors hauling both regional and long distance trains along with the HHP-8's, which sadly proved to be unsuccessful and unreliable. Between 1999 and 2002, 29 AEM-7's were rebuilt with AC traction motors and were re-designated as AEM-7AC's. The remaining ones were designated as AEM-7DC's or simply just AEM-7's. By the 2010's, the AEM-7's were still reliable and still going strong, but were showing their age. Because of this, Amtrak sought plans to replace them and the HHP-8's. Amtrak ordered 70 ACS-64's to replace them. The first ACS-64's entered service in February of 2014 and replaced the HHP-8's first, then the AEM-7DC's, and finally the AEM-7AC's. The final AEM-7's were retired in June of 2016. Following retirement, 2 of those workhorses have been preserved: #915 is preserved with her partner, E60 #603, at the Railroad Museum Of Pennsylvania. Sister #945 is preserved at the Illinois Railway Museum. Sisters #928 and #942 were moved to the Transportation Technology Center in Pueblo, CO in 2017. Sisters #929 and #938 were purchased by Caltrain to test their electrification system once completed. Numerous others are either still in storage on Amtrak property awaiting disposition, or have been scrapped.
