Why is the entire railway No Smoking when the law only requires that of enclosed spaces?
If we were selective about where we allowed smoking we would need a proliferation of large, conspicuous, modern no-smoking signs on every carriage door and loco cab, as well as lines/signs painted on station platforms (since the canopies are substantially enclosed, at least whilst trains are in the stations). These signs would rather spoil the vintage atmosphere! We had banned smoking on our trains a few years earlier, to reduce the fire risk, both on our trains and on the lineside. Not only is a complete ban much simpler, but, since smoking is similarly prohibited on all national rail stations and trains, we are also consistent with the public rail network. Smoking is of course still permitted outside the front of each station.
