Swap the positions of two wagons and return engine to its original position.

The aim of this game is to swap the positions of the two wagons. The engine must be returned to its original position.

To do this you can push or pull them with the engine. When you move the engine or another wagon against a wagon they will be coupled. To decouple a wagon tap on it. To prevent accidental re-coupling you can tap the wagon again. It will then be locked until you move well away from it. A locked wagon has a lock image overlaid on it.

The engine can go through the tunnel (but only twice; the number of passes allowed is shown on the tunnel) but the wagons cannot.

You can switch the points (to access the siding).

Move the engine by dragging it. To do this you should touch it with one finger (or whatever you use for touch screen interactions). If you move off of the engine it will stop moving. If the engine is blocked by something you will need to release and select it again. The engine will \'smoke\' when selected and able to be moved.

The engine will not move if it is blocked by the tunnel (after 2 passes through it), the sidings track, or a wagon which is blocked.

You can't switch the points away from the siding when the engine is on the siding.
