It's on the Bluebell Railway between Sheffield Park and Horsted Keynes, locos are ex SECR 65 (O1 class) and 592 (C) 0-6-0s, working a photo charter goods in September 2008.
To tell them apart - the O1 (leading) has a tender with outside springs, the slightly larger C a wider tender with cleaner lines.
The outside springs on the O1's tender are the giveaway and the fact that the second loco looks like the O1 but doesn't have that feature means it can only be the C class.
