So I uncoupled then recoupled two sets of 395s but the rear set isn't powered and I can't control it from the lead cab. How do I resolve this. P.S. please can uncoupling and coupling be included in tutorials for future multiple units.
It’s a bug or rather, they haven’t implemented the coupling feature properly. You’re unable to obtain brake release on the other unit no matter what you do. In real life, once you press couple button and have electrically coupled, you should get brake release and power across the whole train. As I’ve said on a thread that has just resurfaced in the suggestions section, it’s a shame they haven’t fixed and included coupling/uncoupling scenarios because they’ve done the hard work of implementing opening and closing the hatch.
I looked on YouTube to see if there was a tutorial by someone. The only thing I found was of someone doing it but with an external camera and they were able to successfully couple and drive off.
