Happy Derail Day...!!! 
A real achievement in doing justice to the game title, I just managed to derail my first train ever since I know this game. What makes this even more a special acchievemnt is that I derailed a train that was not there, since I moved the locomotive alone, without waggons. I thought I had the grip for the independent brake firmly in my right hand, but hadn't, then panicking when I started to speed I pushed forward the lever for the air train brake only to find that since last use it still had not charged sufficient air pressure again, and then the independent brake went in and blcokedf the wheels, the wheels slipped, the loco was sliding and then I arrived at that turn and that speed was too high and so...
Bright lights and loud sounds.
