Hello again! Today, I would like to make a small suggestions in regards to Amtrak's ACS-64 Locomotive, and a way to make it more realistic! What is the Regenerative Brake, and how is it used on the ACS-64? The regenerative brake is similar to the dynamic brake in the way it works, the gen fields on the traction motor's are reversed in order to slow the train down and generate power. The way the regenerative brake is activated however is completely different than the dynamic brake! The regenerative brake only activates when the MCB is open on the ACS-64, and will only apply a certain amount of effort in order to keep power on the train. Usually the regenerative brake is used when coasting through dead sections, and sometimes engineers will use the regenerative brake to their advantage when going down a gradient so that they don't overspeed. The recent Amtrak Acela DLC also has the regenerative brake implemented, so if you want to see what that would feel like, go try it out! Why should the team spend time on this? What does it add to the ACS-64 driving experience? For me, I believe that the #1 thing that a train simulator should strive for is realism! The regenerative brake would add realism to the ACS-64 driving experience, and would improve the overall simulation! This update could also be a quick little project for the physic's team as you are not making the physics for the entire locomotive over again! I think that the team should spend time on this because it's a (almost) quick quality of life improvement to the simulation, and the Boston Sprinter DLC! In conclusion, I believe that the addition of the regenerative brake to the ACS-64 would add a bit more realism to the Locomotive while also being a quick addition that improves the simulation. But that's only what I think! What do you think? Would you like to see this added to the ACS-64?
