alt Hacker NewsThis is exactly the reason why in germany we have now a broad ticket for short distance trains. Government realized they fail to meet EU regulations in reducing CO2, so they rushed to implement a cheap german wide ticket. Initially just 10€, now 60€ a month.
Still a bargain, you can go anywhere as mich forth and back as you want (just not the dedicated long distance trains, so going through all of germany takes a bit longer).
You can tell this is a true success in Germany because 95% of local passengers now use it. It also caused a significant increase in ridership, putting the already overloaded rail system under a lot more pressure while taking away income from the rail companies (after making it cheaper).
