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

Pretty nice and easy. Surprisingly, the train was the easiest part! I'm scared for the harder variant, but excited to see if it's as nice as this one

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.

Okay, so I did this puzzle and then tried out the OG. I completely loved both!

The last train disambiguation gave me so much joy

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