Huge 3 Ring Roundabout 4 Way CCW

Sorry... if you want a CW... well you're on your own! This monstrosity has an outer ring and an inner ring, both of which only have exits to the outside, but only have entrances from the middle ring. The outter and inner ring are meant to provide escapes in case the middle ring starts to freeze up. Notice, the inner and outer rings are locked - once any train enters (or fails to exit), no other trains are allowed to enter until that train leaves. This is key to preventing lockups in those rings, and they are backups for the middle ring which is split up into sections and is vulnerable to lockups. The whole thing seems to work, though some of the signals may not be optimal - they are pretty close and be aware that adding more signals can often make things worse. The bridges lead out of the inside ring, provide shortcuts to trains just going straight through, which also alleviates a lot of load. The signals on the bridges are set up for 8 squares, but you can change the repeat rate if needed. If nothing else, this is a lot of fun to watch. Enjoy!
