monorails
Hurray, monorails! A very inefficient system that I know little to nothing about, but is cool and a form of technology none-the-less. Yes, I realize I am somewhat bashing on them. Essentially monorails has an elevated cart going through an elevated line moving around 30-50 blocks per second, if not slower, that just looks cool. You use a car seat to move forward and backwards, and for turns you have to gradually turn it with wedges, I can't really explain it much better then that. Thankfully, when I was taught myself, I recorded the video and uploaded it to youtube so you can learn too. Enjoy!
