After starring at a ERR MiniCommander II setting on my workbench for over a year, I decided to crack open my K-Line Plymouth Switcher last November and install it. I've done a number of TMCC upgrades and knew this would be a challenge. I promised myself I would only work on it one to two hours at a time. I did have trouble fitting the front headlight LED in and spent longer than I should have one evening. The kids heard things coming from the basement they ought not have heard. The simple recipe for this is the MiniCommander II, some parts from Boxcar Bill, (couplers, wiring harness, etc.), LED's, a little ingenuity, and a whole lot of patience. I was able to install a flashing LED on the cab roof as the bd. I used was from a Trackmobile and has the embedded feature of a strobe. I don't know if the stock bd. from ERR has this. The switcher comes with a power distribution bd. which I cut traces and rerouted power to the lantern lamps through diodes used to control directional lighting on the stock loco. This was done to reduce voltage to the lamps to extend their life and reduce heat. The smoke unit is operating, but only through the On/Off switch with track power. At 18V it fills the basement with smoke in five minutes. The antenna is a piece of fine wire extending from the cab to the bell. I need to work on getting that as straight as possible and then tack it to the bell. I figured I have close to 40 hours into this and as I told a good friend, I wouldn't do this again for even the closest of family and friend, but I'll be happy to share my experiences. Sorry if the video quality is not to good.

JC, I have converted my share of these locos to TMCC.  The biggest issue is antenna.  The only place to easily make such is the handrails or "bell rope".  Neither works all that good.

 

The PCB in the inspection vehicle is not a Mini 2, it is called the "RCDR" internally.  Ken has some of these to sell - email him, but I am not sure they are able to run motors without some code tweaks.

 

 

Electric RR made a small cruse board that had tmcc and cruse which would be good

for small switchers but it was dropped for lack of demand.

The LCCA Texas Tommy will be out next month but no tmcc.Adding tmcc with

cruse will be a good project.

 

If JonZ would make the mini cruse commander again, that would make the

project more doable.

Thanks Jon, I will.. I believe it was Ken who upgraded my Atlantic with cruise a few years ago..

Jon, I didn't realize the RCDR had the capability to run a motor, even with code tweaks!  It would have to be a pretty small motor, right?

I never knew they made one of them, sad they didn't keep it.    I am always wishing they would make a smaller board with cruise.  What were it's limits?

With my attempts to tether pairs (and later trios) of Plymouths together to haul my "40-Car Rampage", I thought of ways to get these command-capable, but always ran into the issue of the great difficulty of shoehorning in the only board that would fit (and it isn't available anyway)

 

The proposed solution was to equip one of the Industrial Rail ore cars with a Mini Commander, intercept and re-route the Plymouths' pickups to the motor inputs (using a tether system), and route the motor outputs to a bus line that powers the Plymouth's motors through another set of tethers. Since in this application the original reverse units remain in place, the Mini Commander-in-an-ore-car functions as a rolling PowerMaster instead of a locomotive-based command board. (I don't need the smoke/coupler/cruise/sound functions). Additionally the units can be seperated and revert to individual conventional operation by plugging their in/out tethers together.

 

What I don't know is whether it would actually work.

If you used a car that had pickups it would be pretty easy. Just add a switch on the engine for direct power or TMCC car. I use a transfer caboose with dual pickup rollers tethered to a Plymouth or Beep to alleviate stall issues on switches. Works great. 

But its definitely more challenging to locate everything in the engine itself.

Pete, The Mini Commander from the trackmobile has a couple externally mounted caps that help maintain power thru switches at reasonable speed. I don't know if the stock Mini Commander does as well, but a trackmobile could easily be opened up to reverse engineer as we know. The Plymouth will go thru Ross #4 and Atlas #5's with no stalling. As of yet, I have had no issue with TMCC reception.
