I've been sitting here since the start of this thread expecting to have to contribute an erudite piece on the railways of New Zealand, to which end I've kept my 1931 copy of "the Wonder book of Railways" open at "Trains of the Empire" here, next to the PC.
I now find that we're drifting off into those meaning of word threads - don't get me wrong, they're always interesting. It's just that we haven't changed much this side of the pond since we nicked 30000 of our words from the french six centuries ago and I was really getting into the railway stuff. Of course, not many of those words got as far north as here in Yorkshire, where the populus continue just to grunt at each other!
