I'll draw you up a simple plan using the Ratio signals, but first you have your direction of travel arrows the wrong way round, simple but a lot of us will notice and get all picky!
Trains travel on the left exactly the same as on a road, (hence the BR double arrow which is simply an up and down direction arrow overlapping each other).
You'll need 3 or 4 starting signals, (one might be replaced with a shunt dummy) and a couple of home signals. The Homes and starters all look identical, ie red plate with a vertical white band. You probably won't have room to fit in any distant signals as most layouts are too small.
The signalbox is most likely to go at the end where the entrance to the yard is as the rodding runs would be shorter and easier to pull, but that depended on all sorts or reasons such as if you had a level crossing the box would usually be next to it so the signalman overlooked the crossing and could have the operating wheel in the box.
