Hello:
For your interest here is a link to an auction for a (to me) heretofore unknown
recording of CP steam in the late 50's-none of the modern fan-trip fare but
sounds recorded of workaday engines with few paying attention, now lost to
history.

The seller said he had several like it. I already bought one not knowing he'd
have more. I have no connection personally.
