Allegheny, in efforts to keep the overall length within turntable length, and keeping the same required capacity, resulted in the short but heavy tailed tender requiring a 4 wheel truck to disperse weight.
Ah, gee, here I thought it was a prototype question. That tender is certainly from an Allegheny. The unusual part is that it is a model. :tb-biggrin:
Your half right. From the Allegheny. But there is something a little different about this tender as compared to most Allegheny tenders.
I am pretty sure they are commonwealth trucks but that doesn't answer why they are there. Was this from one of the loco's equipped for passenger service?
Could it be that the tender came from the last 15 acquired by the C&O? Thus building differences due to better engineering? From what I understand was that they never really made it to passenger service....
I believe there were three equiped that way. Around the 6,7,and 8th ones made.I have no idea why. I will research further. They actually were made to run much faster that they ever did. And passenger service was in the plans but never worked out. A mystery continues.....
I am pretty sure I have pictures of a few in passenger service. They were not primary power for sure but some were built with equipment for passenger service. When I get home from the shop, will check the books.
Well I got out my book C&O Power by Alvin Staufer. Here's what it says: Page 209: "Engines 1607-1609 had Commonwealth trucks; all the rest had Buckeyes." Page 173: "The Alleghenies were designed for maximum speeds of 60 m.p.h. in order that maximum continous power output would be developed at speeds of from 30 to 35 m.p.h." "At least 23 of the Alleghenies were equipped with steam heat and signal lines for operation in passenger service. Reports indicate that their passenger duties were usually restricted to heavy mail and express, troop, or other special moves." The picture of the tender trucks on page 209 shows the Buckeye six and eight-wheel flexible-frame trucks. The brass model is close, but not quite right...
Apparently the C&O didnt like the commonwealth truck because they weighed more than the buckeye trucks. The Allegheny had weught issues and since the commonwealth trucks were in the first run maybe they just were making comparisons and in all subsiquent orders only the buckeye truck was used.
