On our steam trains in South Africa our onboard crew is constantly having to stop passengers from standing between the coaches smoking. Apart from the fire danger from dropping cigarette butts onto the dry bush (which would of course be wrongly blamed on the steam engine itself) and the danger of falling off and killing oneself, we have had some of these idiots even trying to climb onto the roof of the train under the overhead electric wires. I make frequent long international flights and I see that the addicts manage to last eight or nine hours on a plane without their tobacco fix, so I don't understand why they can't last just two or three hours on a train.
