Lego Pneumatic Train

A creation of my own design. A Lego train that runs off of pressurized air using modified Lego pneumatic elements. Runs off a single large cylinder. Several iterations of prototypes.

OH! I see. You’re using that worm gear valve to vary the air flow by running the tube through the hole in the gear to squeeze it against some bricks. Very clever… i’m going to implement that in my build.

How do you put the compressed air in the bottle
