Back to my problem. I didn't see any switch showing both ways in red. I ended up deleting the entire branch and re-doing it again. Same problem. I saw a blinking switch on the minimap, went and deleted that junction, I mean, the three pieces of track and then I re-do it one more time. Same problem.
I have a loco 8 miles away from that branch, no one junction between the loco and the branch, it is up the hill, over 8 boards. As soon as the loco starts going the blinking speed dial shows up again, almost during the entire trip. When it gets close to the branch, I guess, two miles more or less, the speed control goes back to normal, the loco speeds up and completes the journey.
Do I need to have intermediate dummy junctions along the 8 miles track? If that's the case, what a crappy game! I spent money and spending time with this game and not having fun, very frustrating. Never I had problems with games before. I enjoy games like Civilization 4 or many others I have.
I haven't had a good shank of time enjoying this game, always trying to fix problems. On top of that, the lack of documentation is a shame for the company which is reselling over and over 100.000+ undocumented and outdated items and I am stupid enough to keep buying their stuff.
