When you buy a A-B-A set, are they already synced so that the two power units are both operating?
If you buy 2 engines seperatly can you lash them to make both power units work? or is it only certain types of engines?

If they have some sort of command control, they should be able to multi-unit together. The instruction sheet should be able to address that issue.
BTW, the word "lash", or "lash-up" on this blog tends to bring out the word police on this blog, even though TMCC/L and DCS both use the term!
Really? OH RICH.........
This way works, even helps when lashing up TMCC and DCS engines

Oh darn I just realized that you asked this on the 3 Rail Scale forum

Penn Central merger?
OK real answer, check the manual for the control system, you are using. The only A-B-B-A unit I have is an older TMCC, I set the first A unit and 2 B units to one ID (B units are the sound) and the other A unit to a different number.
Punishing your locos??? 20 Lashes!!!!

There are two (A units), you would still have to choose the lead A unit, and the rear A unit can be positioned either nose/rear forward. There should be programming options for these choices. (Not a cut and dry set up)
If you buy 2 engines seperatly can you lash them to make both power units work? or is it only certain types of engines? Again not a yes and no answer, there are a lot of different combinations available. I have had very good results with straight TMCC units and TMCC units with EOB speed control. I have posted this video of Atlas SW9 units with TMCC and an Atlas GP7 with TMCC/EOB speed control. It works and works well, all (5) units are powered. Click on the image to access the video.
I try not to comment of general response on this forum, but maybe, just maybe, some need to take a long walk and clear their head on occasion. Just answer the guys question. Mike CT
Well, you could just buy a 2-6-6-2, for example; one loco, two engines and they come
eternally lashed. No prob.

Except on most model articulated steam locomotives, there is a drive shaft connecting the front engine with the rear engine, so they are mechanically connected, and thus not "electrically lashed".
It would be VERY helpful here to state which locomotive(s) you are asking about.
In "conventional" (i.e. using the transformer lever) control, A-A sets often have one powered and one DUMMY locomotive. The dummy locomotive is just along for the ride, same as any other car. Therefore no conflict. Nothing to sync up.
With two powered "conventional" locomotives, you either lock them in single-direction mode (100% reliable), or manually sync up their E-units so that they move together (works most of the time).
Conventional locomotives move in a predictable pattern if their e-unit is working properly. Either forward-reverse-forward, or forward-neutral-reverse-neutral-forward depending on the type of e-unit they have. You just need to get the two locomotives at the same point in the sequence, and they will move together as long as you keep them on the same track with the same power source.
I run several F unit Lashups with ABBA configuration in Legacy. I assign each engine an id number. Then "build" a train using the "train" function. Hope this helps.
