hi guys.  a few of you may have done this with dummys.  I just got this BNSF SD-70 premier Dummy.  it does not indicate it has lights or anything. so I believe its gutted.  not even sure if they come with center pickups.  So, I guess I would need parts to install the lights and stuff.  I dont want it powered because I have the powered unit and its running in the tandum.  But, I wanted to see if you can run smoke units with a slide switch and lights.  its going to be a project.  But I think it would be cool to smoke this thing and light it up.

any help is appreciated! 

thanks

Chris

stack,  Hey I just thought about something that may work, but not visually great.  But, Maybe I can wire in from the other engine the wire that controls that smoke control????  not sure if this trip would work, I guess its essentially the contrl wire for outputs for the diesel on the first engine.  Id have to look into it and maybe others can weigh in on the DCS side of things or some others that do elctronics around here. 
 
boy I hope that mine has it in there.  Its coming today I hope at least UPS said so.

The PS2 board doesnt have the power to run 2 smoke units. Wiring in a 2nd smoke unit would blow the circuit on the board and you'd have none.

There are smoke units that have their own control boards, whereas the PS2 board runs the smoke unit. A PS1 smoke unit is self contained and would probably be a better choice for a dummy setup, although if I remember right, PS1 units were either on, or off.

The Engine below started out as a Dummy MTH Dash-9.  I found a parts list for the powered version of the same era and ordered the pickups, smoke unit, couplers, and interior wall.  Then I installed a TMCC dummy board to control everything.  I did have to make light boxes out of styrene so the head/tail lights would not shine through the rest of the engine.  It works great with my other Modern TMCC Engines.

 

 

 

fellas, thanks.  Bruce.  good idea with swapiing the couplers.  I can make a male female connector and be able to unhook the wire there.  great idea. 

 

allan.  did you just order selected parts from MTH or a dealer?  I thought I bought the same BNSF.  turns out they are 2 different engines!  the 3 photos.  the engine on the left is the dummy SD-70 MAC.  the other is a premier Dash 9.

Allan, do you have pics of the inside as you did it? I wondered about the TMCC board.  never did that before. easy? thanks Chris   would it be Originally Posted by C&O Allie:

got the parts diagrams for the SD-70 Mac of the day.  do you have to buy the number boards or do they light up already.  looks like in my one pic that they are solid. Id have to cut them out! and the numbers are different, so i think they are going to be left behind. smoke units are 50.00.  looks like the bulbs are on harnesses for the ditch lights and the headlights and rear. 3.00 is good.  pickups are 5.00 a piece.  now a TMCC board for this application?? what will it do? operate the smoke unit?  turn lights on and off with the DCS?   thanks

@Chris -

 

I ordered the parts directly from MTH.  To find the correct parts, I looked in the catalog that had the dummy engine and found the matching powered engine.  Luckily, the powered version had a parts list that I then logged into the MTH parts order form and got them, including the smoke unit.  I've attached the Dash-9 parts list I used.

 

As for pics of the inside, I did not take any, but it is really easy to do.  What you will need is the Mini Commander EX from Electric RR (www.electricrr.com).  The basics will be wiring the hot/common from the pickups/frame, and then running wires to the couplers, lights, and smoke.  In addition, you can get a Railsounds 4.0 Board from them and wire that in to the EX board so you have full sound.  The EX board will also let you MU your engines together.

 

Please let me know if you have any other questions and I will be happy to answer them.

Dash 9 Parts List

Barry brings up an interesting point that there is (at least) one MTH engine that drives more than 1 smoke unit.  If this approach applies to your engine, I'd think you could build a tether that sends the smoke, lighting, and coupler signals to the dummy without needing to add any electronics boards (or power pickups) to the dummy.

 

Another option is the MTH powered-slave board.  Yes, it has the electronics to drive motors which you wouldn't use, but it also has independent electronics to drive a smoke unit and lights.  It mimics the signals of the master-unit via a 10-pin tether cable including passing through the coupler signal. If nothing else you might study one of these A-A sets to see how the wiring is done in the master A to branch off the signals to send back to the slave A or dummy in your case.

yes,  even the dummy is the premier type. its all there except the inside stuff.  the gears are there for the motors, speaker area, its all ready.  I have a dash 9 premier engine bnsf that is the powered one and wanted the dummy, then I got it home and saw it was a sd-70 MAC!  but they look good.  i dont care.

Is the SD70MAC a Premier also?

 

allan,  I got the stuff off MTH for the parts. good thing.  they have lights specific with harness plugs.  did you call or order on-line? 
 
The mini commander ex is only 34 bucks.  cool.  and I can run a smoke unit off this also.  thanks ! Chris

well, just got it yesterday.  going to order parts and that board. Ill detail the install start to finish though.  im going to go for a smoke unit for that engine, the board as suggested and the lights with harnesses.   here is the parts list if you need one for that engine. detailed and easy. I highlighted the bulbs that I think are the ones I need.  any of these would be similar. I want factory with tat stuff. smoke unit is like 50.00!  kind of pricey.  then Im up to 70.00 for both!

I'd definitely like to see what you have done already, or at least when its finished

Mike, I thought about that very thing, dumping money into these with no power.  with DCS you can lash up engines, so that might be my thing.  I like it, but I know what you mean.  http://www.mthtrains.com/content/20-2268-1  this is the powered dash 9 proto 2 engine I have.  Im going to keep looking around at shows and such also and the bay.  well see!  maybe Ill keep it and add the 3rd one!  one long a.....  train!

http://www.ebay.com/itm/MTH-PREMIER-BNSF-GE-DASH-9-20-2268-1-CAB-4449-DIESEL-ENGINE-PROTO-SOUNDS-2-NIB-/321095709011?pt=Model_RR_Trains&hash=item4ac2cbb153   there is one on the bay here is the link, but Im not spending that much for one.  I spent under 300 for mine, used, this one is new I guess, so the price is high.  not for me right now.

old listing but this is the price with one that has the lights in it already you switch off.  no smoke.  if I do all of this, I might get some money out of it some day.

That one is not bad.  Its hard to find these engines (even though you have premier, and I RK) lower than 300, well at least it seems that way.  When you say you can do a lashup on the DCS system, what do you mean?  I know when the term "lashup" is used, its two engines together.

mike,  when you put the 2 engines on the same track hooked up, I think that you press lashup on the remote and I believe, never done it, they drive in sync and not against each other.  and I am not sure if you can do this with any diesel and not sure if you can sync a diesel and steam engine either.  I would think 2 of the same engine and you would be good to go.  let the experts explain.....  maybe a topic on the DCS section
