Sackgassen

I always wondered how an U-Bahn puzzle with dead ends would solve. This puzzle should provide a nice twist to classic U-Bahn logic. Enjoy!
Rules:
Draw a connected loop network through the centers of some cells, which may branch or turn.
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.
Exactly two cells per row and column are final stations (i.e. dead ends of the network). Final stations cannot touch each other, not even diagonally.
Sackgässchen (example puzzle with 1 final station per row/column):
Sackgassen (main puzzle):
Solution code: for each column except the last, the number of lines leading right from that column

Awesome!!! Not what I was expecting at all, the dead-ends really enhance the U-Bahn logic rather than changing how things work too much. Really enjoyed figuring out how to fit in the stars.

Phew, that was hard !! Took a bit of time to get used to the dead ends, but it was all worth it ! Some tricky yet satisfying logic in the midsolve. Thanks !

Truly amazing puzzle, criminally underrated! As Wooferzfg pointed out, this was a very fascinating take on ubahn logic, and rather than moving away from it, it usually felt like one just could go deeper than usual into the underground. Awesome!

Ouch. very hard but with nice U-bahn & starbattle logic. Thanks.

Really cool puzzle! I've solved a couple other puzzles that modify the global U-Bahn rules, and I enjoyed this one significantly more because of how much it still feels like U-Bahn logic.
