Plumbing


	When you look at the real locomotive, there are a LOT of pipes. I decided to model only a few of them.





	I started with the lifting injectors. These are located on each side of the boiler and are used to bring water from the tender into the boiler. I used various sizes of brass tubing glued together and then covered them with JB Weld, a two part epoxy. A few details are added, and then I use 3/32” rod to represent the pipes.


	I made some air tanks by putting some rivets in a sheet of .020” styrene and wrapped this around a piece of ABS tubing. I used brass strips to mount them to the running boards on the boiler.

I made the steam turret out of various pieces of brass. Dress snaps were used to represent the valve handles. The steam turret routes steam to the various appliances, like the generator and the air pumps.

Air pumps were made from bits of ABS tubing. I used some 3/32” T pieces to represent the fins on the lower part of each pump. Square brass tube was used to make brackets to hold the air pumps on the boiler.


	A generator was made from some tubing and ends that I cut from my Bachmann Anniversary 10 wheeler. I used a 3/32” brass tube for the exhaust stack. I used some other styrene pieces to create the brake parts underneath the running board. A whistle was added to the steam dome, along with a couple of pop valves. The picture to the left shows the engineer’s side with all of the plumbing in place.

Water lines go from the tender to the lifting injectors on the boiler, but these are seldom modeled. I used various pieces of brass tubing and a small disk of plastic to create the locomotive side piece. A magnet is mounted inside. Black surgical tubing comes from the tender, and it has a small magnet glued in the end. This allows the tubing from the tender to be connected to the brass rod going to the injectors on the locomotive.
