We all have or questions, but patience son!
This is what you call "irratating the pig".
You have posted more than three threads about this, and you know what? A number of people have this problem, it is not fixable.
Please, do quit posting on this subject.
You have two threads in Trainz Community, one in General Trainz, and you probably have one in Russian too.
Why do I say that? You answer that question.
I hope I'm not pushing boundaries by saying this (moderator feel free to warn me, I'll stop) but you really need to grow up.
