== [[Luxembourg]] ==
The local trains (CFL) have two floors; be aware that there is a ticket booth at the end of the first car - don't accidentially run in it, unless you want to buy a ticket. There are ticket inspectors too. If you want to get of the country, be aware that the inspector will check tickets on the international train as soon as it departs, so, if the next stop is still in Luxembourg, you're screwed. The cops are not liberal.
