Japanische Bahnhöfe, Teil 3

Shade some cells in the diagram black and put digits from the indicated range 0-N into the other cells.
- No number may appear more than once in every row or column.
- The numbers on the left side and above the diagram give the sum of connected digits (without blackened cells in between) in the correct order. Single digits are also given.
- For some rows and columns the hints are missing at all; when hints are given they are complete.
- Some of the given numbers outside the grid are replaced by question marks; one question mark represents a one-digit number, two question marks a two-digit number.
Draw a single closed loop in the grid, going only horizontally and vertically, and connecting the centers of adjacent cells.
- The loop must use each black cell exactly once.
- The loop must go straight through numbers.
- Exactly N numbers (except "0") are stations and have to be used in the sequence from 1...N. The loop must not go through other numbers except "0".
- The loop has to cross itself exactly at cells that contain a "0". (A "0" is not a station, and can be used at any position in the loop, even one after another.)
Solution code:
For every row from top to bottom enter the number of cells, in which the loop turns.
Then the marked rows from left to right; use "s" for shaded cells.

Great puzzle! Loved how everything came together at the end, especially those last three cells :)

Fantastic puzzle, a flawless execution of the ruleset! What I really like is that, even though some deductions were very hard, it was always well telegraphed and the resolution at the end was almost effortless. As a result the solve was less straining than many puzzles of lower difficulty.

Incredible! Truly epic puzzle. Thank you very much for this series! The finale to this puzzle was some of the most excitement I've gotten out of solving in a long time.

There are 2 solutions in final 3 cells?
edit: sorry, there is only one solution.

Na, geht doch! Die ersten zwei Versuche hab ich auf der langen Zielgerade vermasselt.;-)
Wirklich klasse, tolle Idee, tolle Ausführung. Und durchweg logisch lösbar. Chapeau!
