Did make sure to remove the brake key and reverser handle from the non active cab?. Both handles have to be removed in order to insert and enable the brake key at the opposite end.
It wouldn't let me remove the handle. Assumed I needed to, spent a few minutes trying to find the right pixel for the option to remove and couldn't find one, so assume I just had to cut it out.
Once I got notification and saw the tree fall my scenario wouldnt go any further I didnt get any messages about shutting down the cab and changing ends maybe I should have been driving faster but I was crawling up to the red signal ? How should it play out correctly ? Artful
You walk forward to the fallen tree. Then you go back to cab and shut down. So, reverser out, brakes off, brake key to cut out and taken out and then switch to the other cab.
Found what causes this. When you switch ends, the game doesn't tell you to cut in the brakes but will let you move the brake lever to running. Once you do that, it removes the option to cut them in.
I am on PC and it took me 3 attempts at this last night. At one point managed to get going in the opposite direction, only to find that I had no brakes at all when it came to the final station. It did not end well! The instructions within this scenario need looking at. It wasn't at first obvious that you needed to leave the cab and approach the tree and also some of steps re the brake key seem to be missing as mentioned above when changing ends.
Same happened to me, have a look at this: https://forums.dovetailgames.com/th...n´t-be-used-solved-by-rtfm.68619/#post-628425
