Here are some images of the inside. I can't really take a video of it with the sides off because the building holds the technic parts and the motor up so it would probably just flop around when i turned the motor on. The 24 tooth gear in the pictures is actually a 24 tooth clutch in my building and the black fork piece just represents the http://www.bricklink...asp?P=92693c01 piece since I couldnt find either in LDD. I also had to adjust where the fork was and moved it further towards the back side of the motor, but that was only because the roof of my building ended up over hanging the track not allowing the trains to go by so I had to position the fork so that the building could be a bit further from the track. I had hoped to fully encompass the switch lever within my building design but then added the overhanging roof which killed that idea.
Some of my piece choices were just from what I had available and was trying to make sure the motor didn't torque too much inside the building. When I get around to building more I'll probably change it up some and make a few different buildings, but for now I want to work on a control box and figure out how I want to wire my train table for more of them.
