Ron, you and Joe are both full of beans. Just
exactly how many 12-cylinder turbocharged 567s
were built, anyway?

Joe, the Santa Fe units lasted throgh much of
the train-off period prior to Amtrak. SF didn't
need them any more.

Besides, one has to wonder why the Mensa candidate
in the Santa Fe mechanical department thought 250
less horsepower would equal the performance 2000.
