Need help getting specific payload cart behavior.

So, I've been experimenting with the func_tracktrain's acceleration and deceleration variables to try to get this to work but have not been successful. Here's the behavior I'm trying to get:

1. Payload cart moves forward automatically after setup time
2. During rollback, payload cart moves forward instead of backwards
3. When players push the payload cart, it moves backwards instead of forwards

So the first one I can do by giving it an initial velocity in its properties or by giving it an initial velocity in the first node path.
My main problem is getting BOTH the 2nd and 3rd behavior at the same time. I can get one or the other working, but not both. Making acceleration negative seems to be a good start, but making deceleration negative breaks things, so I have no idea where to go from here. Any ideas?

I woke up and gave it another go and the settings I was using yesterday (negative accel, positive decel) magically started working. So I'm just gonna give myself a pat on the back here and not question it.
