Wow, that is some impressive pulling power. I have one of these sets brand new i've never run but would like to.

Are there an issues that need addressed with these before running?

Its still in the cardboard shipper. I bought it off the forum here for around $85 if I remember right a couple years ago and just put it away for when I run some conventional stuff but have yet too.

Knowing Gunrunner you have probably gutted them and replaced everything inside. 😄

Well, there is one issue if you use the smoke.  I don't know what "versions" they did it in, but they screwed up the design of the power supply for the smoke fan.  Now, you'd think that would be almost impossible with three components, but they managed to do it!  I have four of these, not sure where the 4th one is, but two of them the smoke fan didn't work.  When I looked, it was wired in a very screwy fashion!  No input filter cap, but a 10V cap across the output of the regulator!  Needless to say, this didn't work well.  This wasn't a simple wiring error either, this was immortalized in the design of the smoke PCB!  I hacked the board to wire the proper input filter cap and lose the low voltage one on the output, and suddenly the smoke fan was running again.  I believe both of the PRR units were that way.

Thanks GRJ, that's code for..... "I'm going to leave it in the box for now" 😄

At one point I had about a half dozen of those little Plymouth switchers. They really were great little buggers! I still have a new-in-box Plymouth Christmas Set, but it likely will go on the for sale forum at some point since all of my current Christmas trains are command controlled. Not 100% sure that I want to part with it though because I regard them as some of the best truly tiny O gauge switchers ever offered.

I'm going to take a stab at upgrading one to command.  If it works, I may do a couple.

Just fooling around with a bunch of Plymouth engines, turns out three of them are working hard to pull ten cars up the grade.

That's Pretty Darned Cool John!

Just an observation here... I noticed a distinct difference in noise level between the grade & upper loop that's just roadbed and the main deck where homasote & roadbed are employed.   I have the same sound difference.  Does anybody homasote their grades?

If it works, let m eknow how much you might want to do one for me. I wonder who owns the tooling for that little gem. Likely Lionel?

I have to figure out what to use as an antenna, that will be the challenge.  I may be able to insulate the front hood and use that.  Since I think having the smoke is so cool, I will likely have to fit something like the MTH HO smoke unit into it to make space for the ERR MC-II board.

John, these reminds me of years ago. When the K line scale Hudson came out I bought two, one was left as is; the other was remarked PennCentral ( I used a decal making program) when I took it to a train club on LI I was a member at the time. I was asked about it, I told them it was a rare transitional Hudson. Love your photos

Perfect for my "High Line!"

I love your version of the High Line! Did you model the tracks going through the building? I wanted to build a version of that on my under construction layout, but I couldn't figure out given my space how to make it work. If I figure out how to have a city area, maybe as a second level, I def will try to make a version of it.
