This problem is solved. I bought European Loco&Asset Pack. After addon installation no problem. Only that, after some miles, I saw a buffer in an grasfield. And then a collision.
I was waiting before a red light but after a quarter it was not chaged in green. So I drive but then the buffers.
I think it's not good waiting so long. It's a game and the player will continue within a short time.
That's all foulks.
Thanks for viewing my problem.
