Traveling through Germany with regional trains was one of my favorite pastimes back in the 90s, but the prices have increased dramatically: The "Wochenendticket, which was valid either on Saturday or Sunday, started in 1995 costing around 11 EUR (inflation-adjusted), and ended costing 40 EUR in 2016 (also inflation-adjusted). I am happy that they are experimenting with bringing it back.
