Two ways to play

Two puzzle styles, one continuous track

A train track puzzle asks you to work out where a railway belongs on a grid. The numbers around the edge tell you how many squares in each row and column must contain track. The pieces already printed on the page are fixed clues: keep them in place as you complete the track.

Both styles use the same counting rules. Every track square connects two of its sides, either straight through or around a bend. There are no crossings, branches or dead ends within the grid.

A-to-B route

Join the two stations

Draw one unbroken line from A to B. Every piece of track must belong to that route.

Closed loop

Bring the track back around

Draw one continuous circuit with no start or finish. Separate little loops do not complete the puzzle.

Start with what you know

How to solve a train track puzzle

1. Count the track squares

A clue of 4 means exactly four squares in that row or column hold track. A bend still counts as one square. Once a row has all the track it needs, mark its remaining squares with an X.

2. Follow the printed pieces

The printed rails cannot be moved or rotated. Continue from the sides they already connect. You can draw a simple pencil line through the center of each square; there is no need to draw every rail and tie.

3. Keep the whole route connected

Use the counts and the available sides to decide what comes next. Mark an X where track cannot go, or a dot where track is certain but its direction is not yet known. Check that the final line matches every number.

In the example here, the left-hand column needs only one track square. The entry at A already supplies it. That immediately rules out the other seven squares in that column: a small deduction that gives you somewhere definite to begin.

A little help when you need it

Three progressive hints, then the full solution

Every puzzle has three hints, called Signals in the book. Each one includes a small map showing what can be established at that stage. Read one hint, return to the puzzle, and continue from there. You can leave the next hint closed until you need it.

The three examples below all belong to Stop 31, Kestrel Marsh, the puzzle shown above. The finished solution is for that same stop. These are extracts from the printed pages, with the original diagrams and wording.

In these hints, ideas A and B refer to counting and checking the available connections. Idea C checks that the track stays in one line.

01
Start hereOpen the first hint
Original first hint for Stop 31: the left-hand column needs one track square, already supplied by A, so its other seven squares are empty
02
NextOpen the second hint
Original second hint for Stop 31: the seventh row has exactly seven available squares for the seven track squares it needs
03
Key momentOpen the third hint
Original third hint for Stop 31: joining two loose ends in the third column would close a circle too early, so both must turn left

The opening pages also include the rules, five solving ideas, and a fully worked example. For later puzzles, each stop points you to its own hints and solution, so you can find the help that belongs to the page in front of you.

The Elmbrook Railway

200 puzzles across five railway lines

The book is organized as a railway journey through five levels. Begin with counting and connections on the Meadow Line, then move into more involved deductions as the journey continues. The puzzle grids range from 7×7 to 10×10.

Later levels introduce short logical “what-if” checks: follow the consequences of a possibility, and rule it out if it breaks a rule. The focus develops through the five lines below.

Five levels in Train Track
Level and lineStopsSolving focus
1 · Meadow Line1–30Count and connect
2 · Riverside Line31–70One line
3 · Valley Line71–120Careful counting
4 · Ridge Line121–165Quick what-if
5 · Summit Line166–200Deep what-if

Each puzzle has a small ticket where you can note the date, your time, and how many hints you used. Take a single stop for a short break, or work through a line over several sittings. All 200 puzzles include three progressive hints and a complete solution.

Train Track is for adults who enjoy working through a problem with a pencil and seeing the pieces connect. If you are new to this style of puzzle, start with the worked example before moving to Stop 1.

After the Summit Line
