This is, in actual fact, only a model. It's one of the most accurate model locomotives I've ever seen, and the only notable flaw I can see with it is that the "soot" around the chimney (smokestack) just looks like a finger smudge or spilled model cement. I think it was in O Scale, but I'm not sure since I don't remember, and in any case the model is far too good to identify as one scale or another based solely on a photograph.

D6700 was the first of British Rail's Class 37 "Growler" diesels, and was also one of the first into preservation. These locomotives, in spite of their meager 1,750 horsepower and 80 m.p.h. maximum speed, are still used today, even occassionally working long-distance passenger services, although these more often than not are charters. #D6700 works charters and excursions exclusively, being a part of the National Collection.
