The LNER Encyclopedia

A recent purchase of a Casserley negative was taken at King's Cross mpd in July 1920 and part of that image is attached to this posting. I've had no problems identifying the portrayed locos with the exception of saddle tank no. 615. Can anyone here provide me with details regarding this loco please?
