This is a little subway I made, I am making a more complex, bigger model. You might say "When did you get interested in redstone?" I got interested in redstone about a month after getting minecraft( I got minecraft about December 2011). It started out as baby redstone, then experimenting, then saying "I wonder if I could make something new...", I never thought of something until now. The bigger model will have a larger get-on station, alot more carts, and a signal light to tell you when the cart is coming. Sadly It will take a while to make it I have to be gone for a little while.
