Chuck Zeiler	General	Hi Gary, thanks for this image. The tender design was the forerunner of the coal pusher. The coal bunker was hinged at the front, and the back was raised upward, presumably by a steam cylinder. This caused the coal load to slide forward to alleviate the fireman from going into the tender and shoveling the coal foward as the supply ran low. The vertical lines are steel braces, the front one ran across the top connecting both sides to keep the bunker in shape. Needless to say, it was not without problems. Most of those problems were when the bunker got stuck in the up position because of material fouling the mechanism. This would require a trip to the roundhouse where a lot of jacking and hammering took place to free the bunker. Some of the locomotives equipped with this device were later converted to oil burners by simply removing the hinged bunker and dropping in a oil tank of the same shape. The division between the coal and water sections of the tender can be seen in the diagon	2/10/2014 12:16:54 PM

Chuck Zeiler	General	The division between the coal and water sections of the tender can be seen in the diagonal line running from the top back of the coal bunker to the bottom front. Some class O-1, O-2, and S-3 locomotives were so equipped. A short description and photo can be found on page 250 in the book, Steam Locomotives Of The Burlington Route.	2/10/2014 12:18:36 PM

Here is a 1915 Baldwin built Pacific (class S-3) sitting in the afternoon sun with its Art Deco style tender. It had tall 74" drivers, developed a 200 psi boiler pressure for its 27"x28" cylinders and had an engine weight of 278,600 lb. It could apply a tractive effort of 46,892 lb> According to SteamLocomotives website, "They represented a revamped Pacific design with a new shorter boiler, combustion chamber, and brick arch. Other improvements were lighter, heat-treated steel alloy reciprocating parts, hollow-bore piston rods and crank pins, and the Laird suspended crosshead, Ragonnet power reverser, and eventually a Worthington or Elesco feedwater heater."
