Train Toy - ABCDary

My Son likes trains a lot, that's because I decided to start this project. The train works with ikea wood tracks LILLABO (http://www.ikea.com/es/es/catalog/products/30064359/) I think these are standard and other brands use the same size.

For the moment I upload Wheels, a Machine and an empy wagon. I am working on the ABCDary wagons. This is a project in progress. Please, if you notice any problem let me know and I fix it.

Hope you like.
