Stibbons, who had already had several rides with Iron Girder over the previous weeks followed by some intense conversations with Dick Simnel, had got the hang of the business and took some pleasure in seeing the best minds in the University coming to terms with their first railway ride.

It was a short journey to Upunder and back, including a dinner at the halfway mark which lasted longer than the train ride itself. On the homeward stretch, the Chair of Indefinite Studies was allowed to operate the emergency brake to the envy of the rest of the wizards, and there was a certain amount of waving of flags, blowing of whistles, and slamming of doors at each stop for the wizards to try their hands at. Iron Girder was in full steam and the fireproof wizards taking their turn on the footplate stared into the fire box and approved.[37]

Replete and tired on their way back to Ankh-Morpork, they considered this new form of locomotion as a phenomenon. The Senior Wrangler thought about objecting again, but was too full.

‘Amazing, people waving at you as you go past,’ said Ridcully. ‘I’ve never seen that before. Who’d have thought it? Machinery making people smile. What are you writing down, Mister Stibbons?’

Blushing, Stibbons said, ‘I like to spot an occasional train, you know … I’m just interested in them … It’s like watching the future go past.’

The Archchancellor smiled and said, ‘Then perhaps we should be the ones who are minding the doors, not to mention the gap, because the future is coming down the track fast. And who knows what is going to arrive next.’

It was a wonderful sunny day. Skylarks sang in the deep blue sky. It was a great day to be alive. Moist, needing a change of air, walked away from the compound with a spring in his step, a little way along the railway track.

And right there on this perfect day … yes, there out of sight of anyone excepting, of course, the ambling Moist himself, on the rail that Iron Girder would have to travel along as soon as she came around the bend on to the little incline leading to the station, were two small … creatures. Rabbits, his common sense tried to tell him, plenty of them around here … even the compound was riddled with them. And, for a moment, the whole world stopped right in his face, leaving him spinning slowly in a little world of his own, looking out on to the real one.

There were the main engine sheds, over there was the crowd queueing for their rides, and there on the track was the future of the railway. It was one perfect moment where time stretched out, and Moist the only witness to this terrible tableau. It was like a strange game of high-speed chess unfolding before his eyes.
