This is a runaway mine cart. It was delivering jewels, which are hidden in the back, when it slipped off its tracks and is now stuck on this hill. It’s stuck because of the rocky terrain it’s on, which prevents it from going farther.
I built this because I thought it would be a fun set to make and play with. This would be a great Lego set for everyone, and especially builders with less experience. It is small and pretty easy to make. Also, I think this would be a great project for people who want a quick, fun and not too hard build.
