Hi, I've watched this tutorial on YouTube from Bill Rizer, about the func_traincontrols.
Hammer Editor Tutorial - Moving Controllable Train, Rail cart ... etc
I managed to have my cart working with the gearbox as in Power Up and the following chapters.
That's a good point.
Further on I remenber that the cart was riding along rails and on the side there were some "switch direction targets" like Railroad switch. When it was hit the train would change its way.
I read the thread Switchable Tracktrain
I've understood that it's about the Branch path parameter but it leaves me in haze yet.
