From that I can see there’s a chain between the rails…so a little carrier connects with something under the truck and drags it up?
I don't think it is dragged up, there isn't a pulley or even enough material to hide a pulley at the top. I looked and the space between the rails is often open, even at the top, so there would need to be something in the center to balance the pulling force.Quote:

The cart's wheels spin in the dirt when it gets to the top and the velocity doesn't appear to change (all guessing from a really short video).
Looking at it with a larger screen it appears like there may be a rack of some sort on the left rail. I can clearly see there's no pulley at the top with the larger view as well.
I would have rather heard the original audio instead of music...but that's just me.
Looks like a couple sets of rollers or wheels for stability and positive contact then a horizontal drive gear that engages the teeth as thevillageinn spotted on the left side of the rail. The wheels align it then the drive gear engages. at the other end it just leaves the rail and the wheels of the vehicle take over.
