Transum's Tram Shunting Puzzles
These puzzles are Transum's versions of the shunting or switching puzzles made popular by train enthusiasts and puzzle solvers.
The objective is to move the trams, represented by coloured circles, onto their parking spots, represented by circles of the same colour but a dashed border. There are buttons to switch the points and make the tram move to the left, to the right, or to stop.
The green buttons control the green tram
Left Stop Right
There is a certain amount of tolerance at the parking spaces so the tram does not have to stop directly over the parking spot but it has to overlap most of the parking space.
Trams can go over parking spaces during the course of the action but you should be careful that two trams don't crash into each other. A crash will require the operation to start again from the beginning.
When all of the trams are parked in the correct places you will have the option of claiming a Transum virtual trophy. On the trophy will be recorded the time it took you to complete the shunting puzzle. You can try as often as you wish and look for time saving strategies so that you can improve on your personal best for each level.
If identifying the colours of the trams is difficult you can add colour names.
