Both actions together, or one of them is enough?
At described case, there ARE signals at both ends of platform tracks, so, this condition is inacceptable, right?

What Do You mean?

the red one is "traffic" train: it
1.starts outside the station (somewhere at pool park's track in real life)
2.arrives to platform with engine at the head for boarding (~10 minutes)
3.performing runaround, as soon as possible, during that time (without success)
4.departs to the branch line, at opposite direction, rather have arrived.
So, it has main path, runaround path and than, forms outbound train.
I should to choose that train and drive its engine manually, trying to perform all of predefined actions.
