Ride on: The tickets cost 9 euros (about $9) and give unlimited regional travel in Germany for one calendar month.

Sell-out: Nearly 60 million tickets were sold in the first two months of the three-month scheme.

Downside: But the popularity of the ticket also led to overcrowding on trains and chaos at some stations.

Jam packed: Security had to be employed to help travelers navigate busy stations.

Deal of the century: The tickets went on pre-sale in May, for travel in June, July and August. Each ticket was valid for one calendar month.

Maybe too popular: One traveler said many trains were delayed, which made overcrowding worse.

Green gods: Air quality improved by 6% over the first two months of the scheme, according to one study.
