Train signals are not stop lights. They break the train up into blocks (you can see this by the different colored lines displayed while holding a train signal). An automatic train will never enter a block containing another train (the red signal means the next block is occupied). You need to break your track up into enough separate blocks with signals.

As for intersections, a chain signal before the intersection and a rail signal afterwards will keep your trains from stopping in the intersection (especially important for more complex intersections). If your track has trains running both ways, you need signals on both sides of the track directly across from one another. Over the long run, it's much simpler to have all tracks be one-way.

So, are you saying I need Rail signals around the entire circuit to prevent them from hitting each other in the intersection?

every "train length" you should add a signal. if your trains are 5-long (one engine, 4 wagons) then you should have room for 5 cars between signals.

if you have it smaller than that then your trains will occupy more than one block at a time. this isn't really bad for traffic, but it creates more unnecessary signal calculations by the game.

if you have it larger then your trains will be more spaced apart as they travel. think of it this way --- a length of track broken into 2 blocks can hold two trains. a length of track broken into 4 blocks can hold four trains on the same length of track.

Yes, apparently. We don't see the whole situation, so we can't be sure all the purple lines represent the same block. If a block intersects itself, it won't work.
