Hmmm....good question. I used a regular sandblasting outfit, with a grit cup about the size of the container used for spray painting (not airbrushing). I wore a leather work glove to hold the trucks, and worked at about 60-75psi, I think. For styrene, which is softer than Delrin, try starting at about 50psi and and then crank it up as necessary. At least with something the size of a freight car, there's no need to get your hand too close to the work area.
I've since purchased a Paasche Air Eraser, but have yet to use it. I got some aluminum oxide grit to use with it, but, obviously, can't comment on its effectiveness - probably too much for paint removal.
