Louis,
Here is your what if of an O-5 with an M-4 tender.
Looking at the folios for the two the M-4 is 5 inches longer and 3 inches
shorter in height. The O-5 caries 27 ton of coal and the M-4 caries 24 ton of
coal, so I am not sure it would have saved stops.

Charlie and All - There was a recent post about a proposed third
set of never constructed Class O-5 4-8-4 types that would've been equipped
with long range tenders similar to those on Class M-4 2-10-4 type
locomotives. Can someone in this Group who is proficient with PhotoShop
try and take some builders photos or other broadside photos of each
class and see what an O-5 with an M-4 tender might've looked like. Sounds
interesting.... Certainly would've cut out the need to stop for
coal and water other than at division points thus increasing
what today's railroaders call "velocity." Best Regards - Louis
