Normal sudoku rules apply.
Draw a "train" in the grid. The train is a line of orthogonally connected cells that cannot loop or branch, and can touch itself diagonally but not orthogonally. Its "carriages" are 2-cell Killer cages. The first carriage sums to 3, and thereafter each carriage's sum increases by 1 going along the train until the last carriage, which sums to 17.
Cells with grey circles are not on the train. A digit in a grey circle shows how many 'train cells' neighbour that circle orthogonally and diagonally.
Solution code: Row 1 (top row), left to right

Lovely puzzle. Thanks. Nice to find an approachable path building puzzle. I'll have to try the harder one next.

This puzzle definitely scratched my train-building itch as a champion Ticket to Ride player.

What a great puzzle!
Took me a while to grasp all the rules. Especially the fact that the numbers you add to the empty grey circles also serve a purpose really opened it up after being stuck for a while.

Really enjoyed this - not too difficult but very elegant and smooth throughout. I look forward to giving the harder one a go soon
