We are enroute from Bratislawa, Slovakia to Praha (Prague), Chech Republic (also known as Chechia) on board a train. We very seldom travel on board trains in the US, but travel in Europe shows that this can be done with surprising efficiency. On this trip, we sat next to a little area where children could watch videos for entertainment, and is one of the many interesting ideas I see on these trains. Trains are one of the things that I think we will have to get back to once the predicted oil peak transpires. I know that airplanes work as mass transportation as well, but trains can actually be powered by electricity while large airplanes cannot. (You probably do not want to ask me where the electricity [or hydrogen fuel] will have to come from).
