I believe the trains were at a salvage/junk yard right in New Castle, not 100% sure which one though. I also see that rcdb has pictures of the Comet now. Not sure when they were added.
As for the Dips at West View, that was my first coaster ever. No kiddie coaster for me, Mom just dragged my butt along with her. That turnaround was a nasty surprise. Scared the poop out of me. Didn't ride another coaster 'til 1976 at Cedar Point. I, sadly, never rode the Whippet.
