I am contemplating purchasing an additional MTH F-3 A-B-A set and see that the dummy A unit has operating cab, headlight, and marker lights. Do these lights come on every time the engine is on powered track or can they be turned off? Might seem a bit odd for them to light in the yard while Im running a different train. I have purchased several of these but have not opened them yet and am considering getting the rest of the set. speperak

The specific A unit I am referrring to is 20-21583-4. It is a recent Baltimore and Ohio F-3 non-powered A unit. The description says that it has cab lights, marker lights etc. I was just asking if these lights are always on when the engine is on powered track. Or, can they be turned off somehow? thanks for any and all replys. speperak
If the picture on the MTH site is accurate, it's a slave unit to be connected to a powered unit. One would presume the lights would be controlled. The arrow indicates the connector to the lead unit.
OTOH, I don't know if this picture is accurate, so I can't say what how the light would function. Best bet is to find a dealer that is willing to give you accurate details.
Thanks, Gunrunner. I did not know that these units were connected electrically. Knowing this now, I can see how the lights can be controlled independly at different times. thanks, speperak
New MTH non-powered A units are not tethered. The lights are usually controlled via switches behind the rear diaphragm. Attached is a picture of a non-powered E8 from 2019 Vol. 2 catalog. I suspect the new F would be the same.
We’ll ask @JR Junction Train & Hobby to check it out when he’s open…
He’s got a set waiting for you
We heard from Phil… he said the headlight controls are included on the switch matrix on the rear of the unit, and that the unit automatically turns off the headlight in the opposite direction when movement is detected.
Hope this helps!
Looks like the new F-3 lights can be turned on or off as needed through the back hatch. I am looking forward to reading the manual to see what instructions are given. I agree with John that the tether would allow remote access via DCS and would be a nice feature. thanks, speperak
