All except 901.HHP-8s gone, AEM-7 DCs gone. How many AEM-7ACs are left?

The UK has several preserved and operational AC locomotives, but no museum with working AC electrification. These locomotives are used on excursion trains on the main line. Interestingly some have even been hired for regular train work to cover temporary locomotive shortages.I think it is 750 volts DC. They run some electric engines sometimes but there is no way that they could run an AEM7.IRM (outside Chicago) has an overhead electric system, however I don't know the capabilities of it. They normally run interurban and streetcars on it, but they do own some regular electric engines (including a GG1). I don't know if they can actually run the regular electric engines on their system. It looks fairly light, but then they don't have much distance to travel, so you aren't going to see speeds requiring a high-tension system.

Celebrate with a buffet dinner, serving swedish meatballs.
Not to mention when their frames started cracking making them not worth the cost to repair anymore too.The GG1s lasted a long, long time. They actually only got retired when the technology became obsolete and they started to be considered an environmental hazard (they were full of PCBs, among other things). That's an impressive run.
It's unfortunate one will never run under their own power again. The preserved A/C MP54s though (if any are still in decent condition) might have a chance, since they didn't use PCBs.Not to mention when their frames started cracking making them not worth the cost to repair anymore too.The GG1s lasted a long, long time.

It's being used for HEP in new designs; also the batteries tend to be significantly beefed up relative to older designs.For regenerative braking (versus dynamic) the power has to be returned to the grid, used to supplement HEP generation, or stored (think batteries in a hybrid car). The emissions standards have certainly tightened since the P42's came on the property, but regen braking in a road diesel (as opposed to an electric) would probably not make sense.
It's not only about energy saved.For regenerative braking (versus dynamic) the power has to be returned to the grid, used to supplement HEP generation, or stored (think batteries in a hybrid car).

I probably should have spelled that out more carefully. The heat dissipation in dynamic braking is a significant issue, and its impact cannot be ignored. Any energy released by the combustion of fuel that is used to run the train (or its services) instead of becoming waste heat is a plus. The new Siemens Chargers will do some regen during dynamic braking which will augment HEP. What I really didn't state (and should have) is that the greatest advantages of regen are seen when large quantities of power can be returned to the grid (like ACS-64), or in a d/e where acceleration and deceleration occur most frequently which would probably be in commuter or short haul rather than long haul.
Celebration Just need another Sprinter or two to weed out a car or two of the weakest rebuilds so another month 3 Sprinters should arrive. Good for Amtrak and customers alike. The AEM-7DC lasted too long considering much better technologies have emerged and the AEM rebuilds are older but are very capable locomotives. Makes the northeastern corridor vastly better from the locomotive side.931 and 945 are now retired. ALL AEM-7DC units are OOS.
The Sprinters break down more than would be expected from new motors. That is not good for Amtrak or customers.Celebration Just need another Sprinter or two to weed out a car or two of the weakest rebuilds so another month 3 Sprinters should arrive.

what would Strasburg want with a modern electric motor? They aim at a turn of the century (19th into 20th) atmosphere with steam locomotives. I believe a Toaster will go to the Pennsylvania Railroad Museum, which is across the street from the Strasburg.915 & 926 are AEM-DCs Only 29 locos were remanufactured to AC
rumor is that 915 will go to the Strasburg Rail Road.
not Strasbourg railroad but Railroad Museum of Pennsylvania in Strasbourg, two very different things.
What's this Strasbourg place?? Never heard of it. Strasburg, I've heard of.not Strasbourg railroad but Railroad Museum of Pennsylvania in Strasbourg, two very different things.
