This is the most interesting Lego creation that you’ll see this year. By a mile.

Built by newcomer Alfred Boyer, this huge Technic steam locomotive really works, and is built from 100% standard LEGO pieces. Of course fire and plastic bricks don’t mix that well, so instead of superheating water to generate steam, Alfred’s astonishing creation uses air pressure to drive pistons, which is essentially exactly the same operation as a real steam engine, only without setting fire to coal to generate the energy.

Four LEGO pneumatic cylinders turn the eight drive wheels, with two speed ‘gearbox’ – if you can call it that – controllable from the cabin. Also controllable from the cabin are working brakes, with shows that press against each wheel through pneumatic pressure, and -amazingly – a working whistle, which diverts air pressure through some hollow bricks to create the sound. It’s a good thing the Elves haven’t figure this out otherwise it’s all we’d hear all day.

It’s a phenomenal piece of engineering and one that probably takes LEGO’s pneumatic system further than any model before it. The only way to really appreciate Alfred’s creation is to take a much closer look – head to Eurobricks by clicking here for the complete build details (where you can also find a link to it on LEGO Ideas), and definitely watch the video below!
