I try to avoid flying, but the German railway is giving me nightmares. I frequently travel through Germany and it is the exception if there aren’t any large issues.
The article itself is very thin when giving its reasons. I’m sure it’s oké for people without the money to spend, but I would rather pay more for increased reliability. If the German summers are similar to how the Dutch maintains their railways, I’m sure they will plan a ton of construction while the masses of people that usually take the trains for work are on holiday. So I’m inclined to see this promotional as compensation for bad summer train service.
