I know, I'm trying to work out why, not only can't I link to the photo I can't seem link to the guys page either. Odd. I suspect it might be because he sells photos, so he has disabled linking and photo URL copying. Bear with me.
It looks like an old Standard stock train, maybe one used for engineering purposes?
Not standard stock - that is one of the original 1903 cars that worked the line until conversion to LU standards in the 1940s. Several were converted to sleet locomotives (de-icing, essentially) after the Standard Stock arrived on the Central.
