Dual U-Bahn
(Published on 12. April 2024, 20:45 by Paletron)
- Draw two loop networks through the centers of some cells, which may branch or turn, but may not have any dead ends. Networks can cross each other, in which case both networks must go straight at the intersection. Networks may not otherwise overlap or touch each other. Each circle belongs to exactly one network.
- A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.
- Solve in penpa
For answer check, only green circle network should be green
Solution code: For each row except the last, from top to bottom, the number of lines leading down from that row.

Great puzzle!
Not too difficult, but some nice logic in here. The crossing adds some interesting stuff.
