Camel Fights

As an addition to my last post, in John H. White Jr’s excellent book, American Locomotives - An Engineering History, 1830-1880 , it shows the Tyson Ten Wheeler on pages 366 - 382. This is a B&O locomotive, designed by Henry Tyson, the B&O’s Master Mechanic at the time. Apparently, Tyson used some of Winans’ ideas such as the variable exhaust and feed pump design. White’s book also shows the Winan’s Camel on pages 347 - 357. As noted before, the Camel’s used a gab type valve gear with a cam operated cutoff, whereas the Tyson Ten Wheeler used a Gooch stationary link motion (a variation of the Stephenson valve gear).

I strongly suspect that any disagreement between Winans and the B&O over the Ten Wheeler vs. Camels boils down to the fact that Winans did not build the Ten Wheelers. Apparently 7 were built by the Baltimore firm of A, and W. Denmead and Sons and 2 more built in the B&O shops. Only 9 were built, compared to over 200 Camels.

At any rate, this does show that the B&O had 4-6-0 locomotives in the proper time frame.

I always found those Erie 0-8-8-0s to be remarkably distinctive looking. Here is another shot of one:

A normal firebox is about as wide as the boiler, so the conventional rear cab is wide enough to have space on each side alongside of the boiler. The Wootan firebox needs all the width it can get, so it is as wide as the cab leaving no space alongside of the boiler.

However, this type of firebox was also used on locomotives with rear cabs with the cab space being entirely behind the firebox. I am not sure why they did not take that approach right from the start rather than digress into the camelback design with its disadvantages.

Camelbacks were not just confined to the eastern carriers with access to anthracite. I believe U.P. used them, but I do not know what they burned. The Hecla & Torch Lake RR in
