It's about time I created a thread to track all of my upgrades, etc. So let's start with this deal from fleabay that I got for $36 shipped. 3 Athearn UP PA1/PB1 dummies with 3 PRR shells that I can swap out. Turns out one of the dummies had metal wheels and geared trucks. Easy re-power here we come!
Here's the lot of them post re-power.
Here's the start of the re-power. Had to hog out the chassis to fit this can motor. Can't remember where it came from. Wish I had more.
Motor hot glued in to place, wires soldered. Ground screw drilled out on chassis. Had some Athearn worm gears from broken trucks.
Catheter powered thanks to Randy supplying these a while back. Since they are tapered, you can build up to the thickness you need to connect to worm gears and motor shafts. The diameters were different between the 2.
Finished product with PRR shell on. Thanks to an envelope from the Orbitron today, I could replace the missing horns on this shell.
It runs great. Smooth and quiet thanks to the catheter driveshafts.

Catheters are a cool idea, haven't seen that before! Is there a particular size or type needed for these applications? Also, do those affect how the loco handles curves?
I believe these are juvenile size. They handle the curves just fine. Surprisingly the Alco went around my little loop without any problems on the bends (15" curves). It was turnouts that it had issues on and I think that's Kadee coupler height issues.
Picked up two more PA1s. These are Nickel Plate Road shells. One powered, one dummy. The powered one needed the motor cleaned. Dummy had a broken tab on one of the worm gear retainers. I'll use the chassis for the other PRR PA1 shell. I'd like to find another can motor to use. Need to do some digging online.
Thanks. I think the #8 would be the best as most motor shafts are 3mm and would give a
nice snug fit.
It depends though, most Athearn motors are 3mm, but if you are planning on remotoring with something else it changes. Mehano motors are 2mm, as are most of the newer Chinese motors - which are 2 - 2.3 mm.

It depends on how the catheter tapers also... The size is the tip size outer diameter. Smaller sizes should fit the 2mm motor shafts. The thickness of these catheters is about 1mm. It's hard to see, but the catheters above are the thicker ends over the thinner tips. The larger diameter tubing makes better transfer of energy.
Next project. Converting the gearing to Ernst and fixing wiring/power pickup on this Athearn SD45. Need to put some shims in the wheel bearings to keep the gears meshed. They slide side to side too much. Runs fine in one direction, but gears slip in the other.

umpdan31: JadeFog: i found a brand new in the box ConCor PRR mail car. Although the ones that I already have are all heavyweights with 6 wheel trucks, this one is a lightweight with 4 wheel trucks. I also picked up a few assorted couplers. Glad he was open again.

umpdan31: The mail car was 10 bucks. Not bad for a brand new car.
