Object: swap wagons A and B and return the locomotive to original position.
 
The locomotive can push or pull one or both wagons. To push the wagon(s), move the locomotive. To simulate the pulling of the wagon(s) by the locomotive, move a wagon into the direction of the locomotive. Of course this only works when the locomotive is actually next to the wagon(s). The locomotive can push or pull two wagons at the same time, and it can also be middle between them.
 
The wagons cannot go through the narrow part of the track at the right side of the board because they are too wide, but the locomotive can go there.
 
In order to simplify the game, the shunts and bends in the track are not positions for the locomotive and wagons; these positions are skipped when moving the pieces around. You can click the shunts to switch them.
 
You win if you manage to swap the positions of the two wagons and return the locomotive to its original position.
 
In variant 2 the lower shunt is broken and cannot be switched. This makes the problem more difficult.
