stuff on steam engine?

[gregc]

where can i learn what all the piping and other stuff hanging on steam engine is?

on left side of engine, what are the two things above the valve gear, what is the horizontal tank(?) above the drive wheels, and what are the 4 pipes above the tank and rearward?

on the other side, what are the two horizontal tanks, the piston mechanism above the tank above the drivers, and the 3 pipes under the firebox(?)?

Hi, the two bulky cylinders vertically mounted on the engine in the top photo are the twin air pumps made by Westinghouse. The are cross-compound, meaning they have a low pressure cylinder and then a high pressure cylinder. It is, IOW, a two stage compressor.

The horizontal tank aft of them is their air storage tank. The closely nested tubes are actually a radiator to allow consensate to flow to the bottom of the tubes so that the air tank contains only air and not moist air or water. The compressors heat the air, which enters the radiator tubing, cools and vapour condenses out of the air, and the air is sent forward with each pulse of the pumps to the pressure tank.

In the lower photo, the tanks are the same, for air. The thin pipes that run forward from low behind the cab I am not sure. The engine doesn't seem to have a mechanical lubricator, so it might be a hydrostatic lube line set, or it might be air lines...hard for me to tell.

Someone is sure to know what they are.

thanks to both of you

In the pix of the 2039, the "reverser" is actually the reverse link, the reverser or power reverse is the cylinder labeled on the 2033.

Ironically if you are modeling after 1945, the easiest way to model either of those engines is to buy a BLI RDG T-1 4-8-4. In 1946 the 2033 was rebuilt into the 2108 and the 2039 was rebuilt into the 2109.

I would look for the "Model Railroader Cyclopedia Vol. 1, Steam Locomotives" by Kalmbach, it has more info than you will want to know. In addition, "Steam Locomotives of the Reading and P&R Railroads" by Edward Wiswesser has more info on Reading steam, diagrams, pictures, histories, built dates, scrap dates, renumbering, etc. No Reading steam era modeler should be without it.

i have the wiswesser book, and just before posting this, i ordered the cyclopedia by wescott. i've also found a nice drawing of a reading I8 in a 1949 MR.
