If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.
Draw a loop network through the centers of some cells, which may branch or turn, but may not have any dead ends.
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.
Solution code: For each row except the last, from top to bottom, the number of lines leading down from that row

Tricky little puzzle. Lot of logic for such a small grid. Very nice.
