Certainly double-decker trains in Switzerland. From the entry
doors you descend several steps to the lower deck or climb stairs to the
upper. Many of the S-Bahn trains around Zurich are so equipped.

I've certainly been on several RB/RE double decker trains in and around
München in Germany...


And then you've got the double-decker trains that go under bits of Paris.
RTAP or RER or whatever. Why does most of the Paris metro smell like a
sewer? London's tubes don't whiff like that. I know Paris is marginally
closer to the equator (and marginally further away from the Arctic), but is
a climate difference to blame? Maybe a diet of snails, horsemeat and frogs'
legs leads to more frequent methane emissions.
