Per that photo, it doesn’t look like there was any standard as to how much to tilt them. As to how, the center plate for the truck is bolted to the tender frame and/or the truck, so it’s a simple matter to install a shim under the center plate to raise the back end of the tender. The side bearings for that truck would also be shimmed a similar amount.

Which is why all of Titanic’s coal is laying on the bottom of the Atlantic. But when in a pile, coal weighs about 50 lb. per cubic foot, while water weights 62 lb.

The EBT coal plant in Mt. Union was what is known as a “floatation plant”. While individual lumps of coal won’t float, they do weigh a lot less than a rock of the same size. So the plant would dump the run of mine coal into essentially a giant gold pan, while pumping a large volume of water around the pan to “float” and wash the coal over the sides of the pan while the rocks settled to the bottom. Kind of the opposite of what a gold miner does, where he wants to keep the heavy particles where the coal washer wants the lighter pieces.
