8 Common Train Tracks Mistakes (and How to Stop Making Them)
Updated October 3, 2026 · 4 min read
Most lost boards come down to the same eight errors. Spot them in your own play and your results improve quickly.
1. Guessing at a fork
Two directions look possible, so you pick one. Instead, count: the clues for the rows and columns on each side almost always rule one out.
2. Forgetting the border rule
No piece may point off the grid. It removes options on every edge square, so check the perimeter early.
3. Not crossing out squares
A square you know is empty should carry an ✕. Without them the board stays cluttered and dead ends stay hidden.
4. Misreading a clue
The number counts squares, not turns or runs. Confirm the row and column totals match before you trust your reading.
5. Drawing before you've solved
Dragging a guess costs lives. Solve the route first, then draw.
6. Leaving a loose end
Every piece needs both ends connected. A piece with an open end means something earlier is wrong.
7. Overlooking the grey squares
The pre-placed pieces are free deductions. Start building from them.
8. Skipping the totals check
Row clues and column clues must sum to the same number. If they don't, you've misread one, and no technique will fix it.
