Hello, I'm kinda new to this game. I have a problem where my loc doesn't go beyond 7 km/h and after that, it decreased to zero, when it stops it won't move again. Here where I got stuck in the game. Next, I'm trying to push the throttle to pick up speed but it doesn't as you can see. Then it slows down and stops. I've tried over and over again with different throttle scales/values but it always does the same.I've seen a vid on YT from this guy that seems to have a little problem at first but then the train starts moving and he even picks up speed beyond 10+ km/h.. So what is wrong or what I'm doing wrong?
