It was Inspired by the little shunting engine from the LEGO City set, 4204 The Mine. The engine is only five studs wide and fits on a 4 stud wide track. The project uses a lot of SNOT pieces and techniques and is described as an affordable train set.
I think this project is great and it stood out to me because of its small size and its ability to work well with a LEGO City. It could part of the Fairground Mixer, or something to go in the city square. I think LEGO City lacks sets like this and I would love to see this being made into a LEGO set. It reminds me of the LEGOLAND train set from this years inside tour set.
Come back next week for another LEGO Ideas pick of the week! You can support the project here and for now check out more pictures of the project below:
