Here's my newest creation - a mini railroad diorama!
Since this is a diorama of a house and since there is a train in the forum banner, I hope this is the right place (and not train tech).
A render of the concept:
The finished scene:
Without the train:
The train in detail:
The carriages can hold up to three minifigs each if the hair piece doesn't need too much space. The train is pretty unstable but it is not meant to be played with. The whole train is connected to the scene at two spots.
I hope you like it!
