Train Track Repair

Train Track Repair scatters a series of broken track segments across the board and asks you to rotate and connect them so a passing train can run the full line without derailing anywhere along the route. Because each segment only has a couple of valid orientations that actually connect to its neighbors, the puzzle comes down to working outward from fixed points — the segments you're certain about — toward the ones still ambiguous, the same approach that works well in pipe-connection puzzles generally. Testing the train before every segment is correctly placed almost always ends in a derailment, which makes planning the full route mentally before running it a far more efficient approach than repeated trial and error. Later layouts add enough segments that solving efficiently really does reward that upfront reasoning. Free to play in the browser, no download or account needed to start repairing track.
