Hello, i am new in the forum. I have some questions about overlap /swinging overlaps
1. Generally we lock and detect a point after the signal if the distance is short than the allowed for the maximum speed of the section. The position of the point (N or R) is accordingly the side that train approach the point.
2. If we provide swinging overlaps, first we set the route after the signal and then we set the route before the signal? Is the any timer between the 2 route set ( first route after the signal, secnd route before the signl).
3. Is there any way to have an unsafe situation with swinging overall ruther than simpy overlap?
4. Is swinging overlap used in other countries expect of British railway?
Please be free to answer!
