I know this is probably what most people go to a railway museum for, and they are indeed marvellous - beautiful beasts, astounding feats of engineering and restoration - but maybe just a bit too much for me to take in, so I concentrate on the peripheral paraphernalia.
They are particularly proud of this one, at the Swindon museum. It's the only loco they actually own, and they recently bought it - bought, not given - from the National Railway Museum at York.
They are particularly proud, of course, because it was built at the Swindon works. They had commemorated the acquisition of 2818 by ordering a large quantity of souvenir mugs, which they were clearly having trouble shifting.
