Not that I wish to affiliate myself with said companies, but I must admit to being a train romantic. Trains are not only potential meeting grounds but also an urban glue with symbolic value for industrialised society.

Rumour has it that when "The Arrival of a Train at La Ciotat Station" by the Lumiére brothers, http://www.youtube.com/watch?v=1dgLEDdFddk, showed for the first time in 1895, the audience screamed and ran away at the sight of the motion picture train rushing towards them. Myth, probably, but a myth that reflects not only our prejudice towards historical times but also our awe of trains as a symbol of modern technology.
Present day train culture includes such highlights as graphic novel Bílý Potok - Alois Nebel by Jaroslav Rudis and Jaromir 99. With the author's own words, at least according to an online interview:
"Our story is the story of a railwayman working at a small station near Jesenik, north-eastern Moravia, in the former Sudetenland, a railwayman who 'sees' what other people can't. He has visions in the fog. He's a bit... maybe ill, mentally ill, but perhaps not. [...] Through these 'foggy trains' on his railway he sees the whole century pass by, good and bad sides. There are German soldiers and there are Soviet soldiers, there is everything that destroyed this region in the last century." This gem is a purchase from my trip, and I will greatly enjoy reading it perhaps already tonight.
