E8A renumbering question


Martin Baumann
 

When did 90A 92A 94A 96A become 91 93 95 97 and when did 26A 28A 30A 32A become 27 29 31 33?

Thanks,

                     Good morning Martin;

                  This renumbering would have occurred any time that 90, and 90A were split up. Initially though two units, the railroad considered them as one. Thus when 90 was down for any reason, 90A became 91, and so on with the other locomotives. ONLY the number boards were changed, not all of the stenciled numbers on the locomotive. Starting in '56 with the new numbering, each locomotive received its own individual number.

Until the 1957 renumbering, these and all other B&O A-suffix units would get the next number higher when separated from their naught-suffix partners.  As needed.  At any time.

Matched sets ran around together for a long time   Like 90 and 90A.  When separated for maintenance or operational reasons, 90A would become 91 for the duration of their separation.    This is to prevent train order confusion.   Any mistake between extra 90 west and extra 90A east on different trains might meet in a cormfield.

The 90A carried three alternate 91 nose numberboards in a small nose compartment fo these occasions..

Because these periodic renumberings were temporary, you will not see 27 29 31 33 91 93 95 97 in any B&O roster.
