In this thread, it's claimed that the photographed loco is a new Meitetsu DEKI. Another poster says it's a replacement for the ED79. I can't tell if this is a joke or not, nor can I tell if the photo is a 'shop. It doesn't seem to be one half of an EH800. This is at the test track of Toshiba's Fuchu factory.
