For most signalling you want the path signals. They come in 2 flavours: both kinds only do the path in one direction, one kind is non-blocking to trains running the opposite way, the other kind is blocking, one way only.
This combo lets you set up an upline and downline with a terminal station: you have one way only signals on the line, and non-blocking signals on the station entrances pointing into the station, and a crossing between. Trains will get to the end of the upline, and wait to get a path to the end of the station. Then they'll turn around and wait to get a path to the downline.

What path-based signaling allows is for multiple trains to make non-conflicting moves through a single block at the same time, which basic signals wouldn't.
- jemmyw 4mo agoThat's not quite true. The original signals would let a train into the cross over block when no station lines were available because they didn't have that pass through. Depending on the layout it would either get stuck or end up heading in the wrong direction. Pre-signals could solve it but they weren't in the original.
- TylerE 4mo agoYou just put a signal at both ends of the passing loop. Just the way they’re signaled in real life - one signal to authorize a train into the loop, one to authorize movements out of the loop. Path based signals (nor pre-signals for that matter) didn’t exist in plain original TTD and constructing such track layouts was easy and straightforward.
