Once in a while, I come across interesting information on unbelievable prototypes. They might be one-off constructions or just something a little out of the ordinary. Your challenge, should you choose to accept it, is to "Model this!"

I've learned long ago that if you're ever given a chance to go out railfanning, do it. It seems that every time I go out to shoot trains, I see something special. To use today as an example, I had an opportunity to go to the Quad Cities to see the double-headed special pulled by the two Chinese steam locomotives on Iowa Interstate. When I finally got to a good photo location, another railfan told me that 261 was coupled into the train too. The train pulled into the town and all three were steamed up and working! Bonus!

Did you know that Louis Brennan successfully demonstrated a gyroscopically balanced monorail in 1909? It was designed as a cheap method of building transportation infrastructure and the British military was interested but it did not enter production due partly to fears of the gyroscope failing. Model this!
