Two significant takeaways from links are a maximum speed of 125 mph and a time of 8 minutes to attain that speed.

It's a lot shorter than that. The time to go from 0 to 125 mph with 8 loaded cars (the wrecked train had 7) is 2:45. The time to go from 70 to 106 mph is just over 45 seconds. View the link at my post #118.

Thanks for the correction. Another video on YouTube helped to answer another question I was pondering. The position of the train engineer is on the right side of the cab.

Interesting and still reading about this model. I found that it has regenerative braking.

Amtrak Cities Sprinter (ACS-64) Locomotive, United States of America

I am still looking for the specs on emergency braking for the ACS-64.

I was off by about 10-15 seconds; post #290 says the NTSB calculated the time from 70 mph to impact as 65 seconds topping 100 mph at 16 seconds before impact (49 seconds from 70 to 100 mph and a few more to 106). I read else where he applied the brakes at 3 seconds before impact but speed had only dropped to 102 mph when he went off the rails.
