Made with the bricks only from two sets called 4837 Mini Trains.
This is a picture that has been computer edited to make it look like a painting. The original picture was very blurred. At the end of this train is the "caboose". (some sort of carrige at the end, it had lights on it and provided a good place to chuck up.)
The original idea came from a friend of mine who actually has three of the 4837 Mini Trains set.
