Dave Olson posted:The original AC-9, the ATSF 3751, and the Legacy AC-9 whistle all come from the same recording of the ATSF 3751. For the original AC-9, it was pitched lower. We pitched it higher for this AC-9 release to make it closer to the SP Freight Whistle as HW mentioned above.
Good choice, Dave. For what it's worth, back in the American Freedom Train days, we carried a big Santa Fe 6 chime whistle on the Fireman's side. That whistle was returned to the owner in 1977, at San Louis Obispo, CA. In later years, SP 4449 did cary a, SP freight whistle on the Fireman's side, and both sound pretty similar. That really nice SP freight whistle, which was owned by one of our longstanding crew members, was stolen right off the locomotive while she was still in the SP/UP Brooklyn Roundhouse, in Portland , OR. We no longer carry any whistle on the Fireman's side of SP 4449.
