From point A, through B, to C, there is a railway serving a large number of trains.
At point B, a train wants to enter the railway, but stops at a signal as the tracks are currently occupied. Now when it enters, it will do so at a low speed, blocking the entrance for an added period of time, which then blocks the next train, and so on.
What techniques can I use to make point B more efficient, and not slow down a lot of trains?
