Do you have a source for that? Considering that the federal government considers 2.5 billion Euro enough to cover the costs, this sounds false. As far as I'm informed the transport authorities will just get their current costs covered.
But to put that into context: with 2.5 billion Euros, you could finance 12.5 million such 200-euro-subsidies, or a ticket for three months for about 5% of the population, which I think is not too pessimistic - I'd wager that's about twice the number of people who have a net-wide ticket for their respective ÖPNV-Verbund today.
The Länder of course consider that money too little and are trying to get more cash assigned, though.
As a non-American, I'd appreciate some further elaboration.
Which was the inspiration for Germany's youth to - very loudly - start planning the invasion of Sylt to drink cheap beer from tincans and do lower-class stuff.
Add our liberal-democratic federal finance minister to the mix, who will get married on Sylt in mid-June, and you got a perfect storm.
Something very similar happened in the 1990s, when the Bahn had a cheap ticket - back then, riot police was sent to Sylt to avoid lower-class tourists getting too annoying. This time, though, it's likely going to be a lot worse, because of things being more organized thanks to the internet.
But even though it's an island, it's reachable by train via a dam, and the locals are worried about being overrun with day trip tourists, and the clebrities are worried about being crowded by poor people.
1. The casual public transit rider will get one of these tickets: 9 Euros is like three rides on the Berlin subway ... they ride cheaper beginning with the fourth.
2. The commuter will save some money on the monthly ticket for three month.
3. Because of the media frenzy about these 9 Euro tickets, many non-users will buy it with plans to go sightseeing, as this ticket still is cheaper than most individual routes. Not all of them will actually use it.
4. Sylt (think 'the German version of Nantucket/Martha's Vineyard') will burn to the ground.
