How to address a Legacy Unpowered Unit

Bob-

 

The best way to address the A-A set (the B unit does not count, as it does not have a Legacy receiver) would be to assign each unit its own ID. Using the lash-up/train feature on the remote will allow you to run the set together while retaining the ability to access the features of both units.

 

It is possible to set both A units as the same ID too, but then each engine will respond the same way to whatever command you issue. This is a good idea for commands like smoke unit on/off, but then problems arise when it comes to opening couplers. For example, pressing the "front coupler" button on the remote will open the front couplers on both the powered and unpowered A units at the same time, even though the unpowered A unit is connected to the rest of the train.

 

The best way to describe how Legacy (and TMCC) works would be to use a TV analogy. Picture your locomotive as the TV, and Legacy as the broadcast station. Several TV sets can display the same show simultaneously as long as all of the tuners are set to the same channel. Thus Legacy is broadcasting commands, and any locomotive set to that digital ID# assigned to that command will respond.

That's what I thought.
