One more thing before I head out of here:
Morrigan built a railroad to nowhere in Minecraft. It’s about 15 blocks long and made entirely of powered rails. Redstone torches line the entire track. At either end there’s a 1X3 “dip”. The train itself is moving back and forth between the dips pretty fast , but I think it has 8 cars. At present there are three Creepers, two cows, and a sheep trapped on the train. It’s beautiful, man.
