Mystery Engine, and Where have all the pictures gone?

Firstly, I’d be interested to know the origins of this loco in the Kintetsu station at Shio-Hama (I think). All I’ve ever seen on the Kintetsu line is the endless procession of EMU’s so this got my attention. I suspect it’s an older loco retired into the depot to shunt EMU’s about, but any info is appreciated. I'm sure someone out there knows.
Secondly, I’ve realised the Blogger has started limiting the amount of space I have for pictures, so from now I’ll probably just have a small one like the one on this post, an it will be a link to my Flickr Gallery, unless the prototype is relevant for my own modelling purposes. However, I'm still taking loads of pictures: have a look here for more JR images and a set of shots of the standard Gauge Kintetsu line, with detail pictures of things like pantographs and overhead power supplies.
