It has something in it... it has a "run/program" switch. It also has a backup light that seems to work correctly. I like the idea of no tethers between units, but don't like the idea that you could have the isolated B unit with no specific direction from the lead unit that could end up out of sync... this of course, is when running conventionally. With an MTH multi-unit engine, this can't happen since all the "intelligence" is in the lead unit. My A-B-B-A N-S F-7 runs like a top in conventional. The only problem I had with that engine was peeling paint on a B unit body. I sent it back to MTH and they replaced it. The Lionel engine, although new, was bought from a private seller. I'm taking the B unit to the train store today or tomorrow. It will cost me $$, but the single unit has some trouble pulling the train up the slope with 9 cars. I have to run at 19+ volts. My MTH GG1 pulls the same train at a lower power input with two motors.
