Task 1	You used bidirectional signals, but it is better to place one-way signals and set the direction of train movement yourself. Like this. At least you used the old signals 🙂, not the route signals.	3/5
Task 2	This railway junction could primarily be improved by adding right turns before the intersection (for right-hand traffic). This way, trains would not enter the junction and block it. The next step would be adding tunnels for straight-through traffic (then straight movement would not block the junction).	3/5

Thank you for taking part. Although the old signals have been replaced by new ones, some players still use them. As for transport interchanges, that comes with experience. I hope you will sometimes play this game and write posts about your experience on Steemit.
