Next on the upgrade list is an MTH A-B-A NKP Bluebird set. A couple questions here if you can give me some direction. First, I believe all 3 units are powered. If that is the case, do I need a cruise commander in each unit? If that is the case, I may opt to make one unit a dummy to cut the expense. My thought is to make the trailing A unit the dummy so that I do not have to tether all the way back to it. However, it would be nice to have the B unit as the dummy so I could use the other A unit alone.
Thoughts and suggestions?
