Hi all, hoping someone can help me out. Just bough this train on Ebay (Mikado 6-18080) and it showed up today. Well it showed up today and as luck would have it its not working correctly.



I own several other TMCC engines, and am familiar with their operation, but I cant get this one to take an ID. It will also not run conventionally.



The Tender does make noise, and it has a light in the firebox when power is applied, but that is all.



Any ideas on where I might start trying to fix?

Things I've tried...

Opened the shell and looked for obvious lose wires or connections.

New battery

Did a reset but it didn't seem to take

Removed battery



My guess is that either a vital connection too the tmcc component had been disturbed, or some component of the tmcc board is fried.

I’ll agree with Pete on this one, you got a heck of a deal, even if it was misrepresented,.....everything Pete mentioned is true,....those are hands down the best Mike’s ever built,...they usually trade 2 to 3 times that price.....I’d try to get the seller to pitch in and help, if not, pick up a radio board, program it, and run it!...a lot of power in that Mikado,....I own that very locomotive, it’s a true brute!.

I went ahead and purchased the C08 board for this engine all the same. 

It does seem to be working just fine though with the C11 board.   I did try it with the tender and all functions appear to work well.  Crew talk, reverse light, forward light, smoke, all of the aux buttons on the controller, rear coupler.

I'll enjoy it with that board until the C08 arrives.  Once it does I'll put the C11 back in my old baby Berk and put the new C08 in the Mikado.

Thanks again everyone.  Made my day to get this running!  Officially the coolest train in my humble collection.

I wanted to add something to this thread.  I received the C08 board and tried it in my Mikado.  It would not run which confused me initially.  It would take a program code, but acted a bit odd, and would not run.  It would whistle sometimes, and other odd functions.

I put the C11 back in and its working great.  This has me curious so I did some research.

I found this thread https://ogrforum.ogaugerr.com/...c-interchangeability which mentions that the C11 is for odyssey locos.  This is an odyssey which I assume is why the C08 will not work. 

Fortunately the C08 works in the baby Berkshire that I took the C11 out of.  So I'll just leave them swapped and run them that way.  Just thought this may be useful info for someone else so I'll leave it at that.

Hold up...

The reset/restore code for that loco is 74, not 740. But that would only prevent the RailSounds in the tender from operating correctly... the loco would still perform OK with the incorrect 740 code.

The R2LC-C11 should work fine, but like the others have suggested above, it's never a bad idea to get the correct revision of a board if it's available.

Interesting!  I had been following this process from the manual I downloaded... Pictured in this post.  Is perhaps 740 a misprint?  I may switch the boards back and try again at some point.



Also, is there a parts diagram somewhere of this engine that confirms which board was originally included?  I'm just curious if you all are referencing a parts manual that's available or if you are speaking from experience regarding c08 being correct?  (Not doubting anyone, just trying to learn)

It's a misprint. The 740 code is used for exactly two locomotives which contain the original, non-modular form of the AD20 board in the tender. The correct code for your Mikado is definitely 74.

I could have sworn that an illustrated parts break-down was completed for those locomotives, but I'm not finding it online. But there is a photographic record shown on the parts order page. I never trust these 100%, but that list is showing a R2LC-C08.

I've re-thought this portion of my response. It's likely that having a 740 code in the R2LC would do more than preventing the tender sounds from operating correctly, as the DCDS necessary for movement also follows the serial commands.

The short version... pop your R2LC-C08 back into the Mikado, and restore/reset it to 74. I'm betting you'll be back in business.
