In what she says is a "love letter", Nadine Kriegelstein writes that since moving to "rainy Manchester" she's not only had to deal with the bad weather, but she's also struggled to cope with the city's “lousy” public transport.
"Often you only realise how much you appreciate something, when it's not there anymore,” Kriegelstein wrote. She goes on to complain that public transport in Manchester is “completely overpriced” and unreliable and that she pays €69 a month for her commute. In Vienna a monthly travel cards costs just €48.20, and a yearly ticket just €360.
Kriegelstein, who works in media, goes on to say: “I just want to say thank you - for being almost always well informed, for sticking to the timetables, and for putting up with the grumpy Viennese who jump onto trains a second before the doors close.”
“Thank you for a fantastic, affordable public transport system. I miss you every day and I know someday we'll meet again.”
More than 2.5 million people use Vienna's public transport network every day, but it's not often that it gets such a heartfelt message of thanks.
The Wiener Linien responded to her Facebook post by thanking her for her kind words. “We're always trying to improve our performance, and so we're really pleased to get your message.”
