Hi.
I figure these aren't bugs, so it fits here.
I realize that the devs can't really make small adjustments to the timetable without creating conflicts elsewhere. However, some of these issues creates consistent problems that probably should be dealt with.
At WP I see 16xx usually creates conflict/delay for 61xxx and then 61xxx create delay for 412xxx. I usually let 16xx wait until 61xxx has passed. I think that is ok to do since it is the end of the route for 16xx in the game. A PT/PH for 16xx would easily solve this problem.
61xxx is booked for track 5 platform 2. This often create conflict with 54xxx. I think it works better to let 61xxx use track 4. He also have an exit at 100km/h that way. 61xxx and 132xxx might be in conflict with eachother this way, but overall I feel it works better.
