You need neither one way signals nor waypoints but you do need a signal at each end of your double track or passing siding.
Transport fever passing siding.
All passing by segments should work like roads do.
Passing loop or siding passing loops allow two trains to share one track.
Passing siding configuration when a second train is added to this configuration both get stuck in the station.
All passing loops in tpf2 are dynamic so intended that the trains pass at line speed therefore each loop is effectively a small double track section so all trains should be signalled to go right or left into the loop.
I already prepurchased transport fever and tried out train fever a bit but found the system with signals to be very confusing.
Learn more about path reservation in the examples below.

Signals in transport fever are path signals.
Despite the passing siding they try to reserve the path to the next stop or signal on the way.
You would need passing loops at 1 3 and 2 3 along the route based on how quickly the train can get there.
These trains can share a line or be on two separate lines.
As there are no signals in the passing siding section the path covers all the way through to the end of the other station.
Terminals or those where trains have to reverse to go back b siding opportunities where you need the train to.
