Csx Ai Trains Use Passneger Speed Limits.

I decided to ride along one service, and it pretty much followed passenger speed limits. At some point I had GE locomotive (with top speed of 70 mph) fly at 79 mph. It's actually quite impressive that the line has both of them programmed, even though there's no passenger trains on it, but I think this needs fixing. And I don't think it would be hard to fix, now would it?

Also, all Class 66 trains are set to follow MU speed limits, which doesn't look right. I believe this is a known issue, but across several updates, still no fix for it?
