Slight correction, JamesMC - Railblazer did in fact reopen after the tragedy, but it only remained Railblazer for the debut year, which was 1984.
On my one visit that year, I rode it several times. Due to the accident, operation was down to a single train, and each standing position saw a lockable waist belt that could only be opened by a special key. There was approximately 10 (no joke) ride ops on the platform, and I saw multiple ops taking notes on a clipboard. Due to the slow loading, and probably due to the unpleasant ride experience, the park made the wise decision to change it back to the Mine Train. The "Big Bad John" side remained in operation through 1987 and was SBNO through the next season. The park placed the one-season-only Condor within a portion of the coaster, and during the season that side saw the drop after the second lift cut off in half.
Ride experience on Railblazer? Think of what it would be like to stand in a fiberglass shower stall, and to have someone shake said shower stall back and forth violently, and then try it with a toilet seat over your head. Yeah, not so pleasant.
