Train show is over and we had a couple of semi dry days this week, so got in a bit of winter track work, and sorted out refitting the air brakes and mechanical Oiler on the 1065.
Last summer I made a big design error on my portable bridge sections leading into the turntable area. I overlapped the rail across the joint between the two sections. Hence it was very difficult to separate and lay each bridge section back into line when I needed to move them off the driveway. So used the cutting torch to lop off the overhanging 2’ of rail on one end, and welded it back onto the short end on the backside of the bridge. This gives a clean joint for running the bridge section back into place. The two photos below show the final clean up work along the welded rail joint. Extra gang volunteer Forman Eric Lindbeck is doing the heavy lifting with the grinder.
We also accomplished the annual boiler hydro test. Passed with flying colors. Pressurized the boiler to 200 PSI with narr a leak and no creaks, except for an errant loose fitting on the blower valve. Easily fixed.
This photo shows the back head plumbing immediately after the hydrotest. Plenty of valves, levers, and copper pipe to check, refit, and re attach, prior to bolting the cab back on. So far, all is well.
The last two pics display a cross head driven air pump mounted inside the steam chest, up against the saddle. The pump shaft also apparently drives an inline secondary water pump by means of an extension rod leading aft towards the drivers.
Anybody recognize this dual action pump design?? I have figured out the air pump, but the second, piston style water pump plumbing seems quite odd. Unfortunately the prior owner left me with no info on how this works, or even if it is effective.
The water pump is held in place by the faded red painted mounting bracket bolted to the frame, just forward of the driver in the picture below. A water line leads from the tender to the rear of this pump, then loops over the top of the pump housing through the piping seen in the photo to the front of the boiler where it joins back into the main injector line.
The small 1/8” copper tubing joined to the water line is an air line of some sort. Seems like an air assisted mechanical water pump! This seems like a very weird design. Anybody know anything about this design?
Thanks
