To what track speed is the Auto Train limited, because of its auto carriers?

I don’t believe it’s limited because of the autocarriers. I believe it’s a 79 mph train, the same as the other passenger trains on the route.

Seems like I heard 70 MPH but the source i cannot recall. Any one have an ETT?

70 MPH is the maximum Auto Train speed.
