Locomotives with only a rear 3D cab aren't managed properly

"There's one thing I can't get working right now. To put 2 3d cabs on the front and end vehicles of an electric train composed of multiple units. In this case there are three but they could start being two and then be more.

I create the two cabins, inverted one with respect to the other, I put the necessary codes, but when I enter the game, when I change the cabin through Control+E, I appear in the other end of the vehicle although the data are inverted with respect to the head vehicle.

If I press Alt+1, indeed appears the 2d cabin, but then, when I put the inverter in forward, the train moves backwards, as if it was still in the front cabin."
