They used to do this during the days of FearFest with Boo Blasters. I wish they'd continue this tradition, especially with rides like the Train or Antique Autos. Ideally, I'd love for actors to hang out and scare folks or bring holiday cheer in various scenes during the train ride. Even some subtle overlays - maybe different lighting or projections - would look awesome. If all else fails, during Haunt, have a couple of scare actors jumpscare us in the queue...
