FEF was simply the class, not a name. It means Four-Eight-Four. UP did not
have a name for their 4-8-4's, they just called them four eight four's. They
had the FEF-1's, FEF-2's and the FEF-3's as they were built in three orders.
844 is a FEF-3. This was the standard way UP classed their steam locomotive,
usually the first initials (or initials) of the generally accepted name of
each locomotive type.
The first 4-6-4 was to have been the Milwaukee Road F6 which were going to
be "Baltics", but the CMStP&P did not have the funds to build them and the
NYC got the naming rights with their J1a 's.
I've seen "Baltic" applied to the 2-6-4 type (a common Lionel wheel
arrangement!!!) as well.... and it is a relatively common type for Europe.
4-8-4s had several names.... Pocono on the DL&W, Dixies on the NC&StL, and
the SP seemed to always refer to theirs as GS (Golden State or General
Service) and UP as FEFs. And of course, during WWII, the Mikado was
renamed MacArthurs for obvious reasons.....
