I love steam locomotives, I always loved their noise and to watch the mechanism working with so much accuracy and power. Therefore, I decided to build a model working with compressed air, to imitate as much as possible the way a real steam locomotive works. Some beautiful models of steam locomotives already exists in Lego, but they are working with eletric motors and have a small size to fit the Lego railtracks. By using Lego Technic parts and pneumatic parts, I thought I could make something bigger and closer to the way a steam locomotive works !
You can watch the model working in a video here :
The model reproduces the functions of a real locomotive, using compressed air from Lego pumps :
- The Locomotive can move foward, at two different speeds, using only the force of compressed air.
- An air whistle, built with only Lego parts, produces this typical noise that we all know.
- The brakes, working with compressed air like in reality, can stop the movement of the train.
All of these functions are controlled in the cabin with pneumatic switches, like a real locomotive would do.
It works using 4 big pumps, some air tanks, 4 medium cylinders for the engine, 1 small cylinder for the brakes. A free wheel is hidden in the locomotive, helping the wheels to work smooth. The locomotive comes with its tender and rails, for a size of approximately 80x10x20cm.
I believe this model could make a great Lego set for some reasons :
- It is one of the firsts locomotives made of legos that works with compressed air, using only Lego parts.
- Everybody knows these historical trains and could like to have a Lego model from it : young people have seen them in several movies and the older generations may have even seen them in real.
- I think it is fun to control the movement/brakes/whistle of the train from the cabin. This may help people to understand and appreciate the way a steam locomotive works.
I hope you liked the model and maybe support it !
