Puzzle #158 - U-Bahn

The second of a pair of puzzles I wrote after feeling inspired by a daily U-Bahn series on the Cracking the Cryptic Discord server. This one is rather difficult.

Rules


Draw a totally connected network through the centres 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.
 
Difficulty: 9/10
