After the discussion re legal issues, and DCC woes,
now an update re the coach....

Yesterday evening I had this thing already running
(although only on two leads from my trusty Kleinbahn transformer)

... then I studied my Illinois Traction files for some details....
found that this thing most likely is a trailer coach...

So the motorized floor went into the parts box,
and I have just begun to assemble a second floor,
without provisions for an power truck.

>sigh

Interesting...  so there is no "intellectual property" on three dimensional objects?


No, except for sculptures and in some jurisdictions architecture, 3D objects have no copyright.
They can be protected by design patents, but these are restricted in effect,
limited in duration, and usually need to be applied for.

If you think about it, it makes sense, if copyright did exist in 3D objects,
you could never make a model of anything less than 70 years old.

Similarly you could never take a photo of anything as that would create a derivative work.  

Also the OEM car parts industry would not exist -
you would have to buy all spare parts for your car from the manufacturer.  

Copyright exist to protect artistic expression, not technical excellence.

Okay, I get what the problem is. 
Sounds like what we need is an electrical genius to figure this one out. 

The only thing I can suggest is maybe somehow using Bachmann's EZ Command Auto Reverse unit. 
Though not sure how to wire it up, or if the idea would even work.

Back then, we  thought about converting a plain two rail DC layout with overhead,
so it was possible to run two or even three trains simultaneously, the old traditional way. 

Train 1 uses both rails.
Train 2 uses left rail + wire.
Train 3 uses right rail + wire.


That will never work with 3 trains.

If say you apply power to train 1, then trains 2 and 3 will be connected in series,
and will start moving at half voltage in opposite directions.

Ok, makes sense. 

Never have actually tried this...  seems to be an urban legend.


Just now, soldering queenposts and truss rods to the new trailer frame.

Let's say, the left-rail is at 12 Volts.
The right-rail is at 0 Volts.
The wire is at 0 Volts.

The train running from both rails, will go full speed.
The train running from the left-rail and wire, will go full speed.
The train running from the right-rail and wire, will not run at all.

Set the wire to 12 Volts, and the wire trains will swap operation
(12 Volts on BOTH sides of the motor = 0 Volts)

Now we set the wire to 6 Volts.
Both trains running from the wire, will run at half speed, but in opposite directions.

In other words, it won't work well.
