I have a suggestion. Now as any player already knows, the TSR is a great gameplay to the game. My suggestion is to make them longer than what they are currently. It's like you're going through them for only a few seconds and that's it. Now, if it's possible, make them for a half a mile to maybe 4-7 miles with some cases being that the track is closed due to maintenance and got to switch over to the oncoming track. That's when the red signal can be put to good use. Same for UK, Germany and other kilometer speeds and routes because there's almost never a train getting to its destination on-time. I'm sure other players may have some feedback on this. If possible, please make a gameplay modification. Thank you
