alt Hacker NewsYou 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).
Well yes, the idea is to have more people use the trains, so yes also more trains are needed(and more investment and replacement of the Bahn management) in general, but as far as I know there is no income taken away, as it is subsidized and compensated on the federal level.
