I used a train on my tour this summer betwen Austria and the Czech Republic, after crossing the border the train stopped at the first station in the Czech Republic. The Austrian train crew got off as a Cz crew took over and the Cz guard told me to take my bike off the train as it could not be carried any further. After some discussion on the platform between the train crews I was told my bicycle could be carried, but this was as a special favour of the dining car crew. I could put my bike back on the train, but in the dining car this time, and I would be expected to consume food and drink purchased from the dining car. As the train approached Prague I settled my bill for the food and drink and thought it not unreasonable to include a tip for the cycle carriage. On returning to my seat I realised an extra beer had been added to the bill, just in case I hadn't tipped, I suppose.
Anyway, that explains the bike in the dining car picture from my 2010 tour.
