Lashup: Legacy Power / TMCC Dummy

As I recall reading here, place the TMCC unit in the lead position and the Legacy unit (set to TMCC on Cab-2) behind.  You have to give up a little bit of features to gain the extra pulling force.  

Here is good thread on it:

If there's a TMCC locomotive in the mix, you can't access the Legacy features in the MU.  The solution?  Buy more Legacy.

If you want to keep the powered engine's Legacy features, you are running them the right way and the dummy will not respond to Legacy lash up commands.  You could put the dummy in the lead so you have a rear coupler.

If you want the lights and coupler on the dummy unit to respond to lash up commands, you need to set the Legacy engine to TMCC mode and run the consist using TMCC lash up commands.  You will lose the Legacy speciific features of the powered unit.

Because the TMCC unit is a dummy, I don't think it makes any difference which position in the consist it is.

I didn't notice the TMCC was a dummy, as Ron says, that changes the situation.

Thanks guys -too bad Legacy wasn't designed to handle this scenario. It's not worth $250 to buy a Legacy dummy and swap shells. So I'll control the dummy coupler with ENG commands, and live with the lack of directional lighting.

Would it not be possible to run the entire consist as TMCC, which would then allow the couplers to function? Again you would lose some Legacy features.

That's actually what Lionel suggest you do to mix TMCC & Legacy in an MU.

Except he does not want to lose the Legacy features of the power unit.  The method he is going to use works for him for this powered/dummy consist.
