Can anyone please help me identify this loco? I've searched the net for hours. It's a 0-4-0 at a restaurant near my home. I've been over this thing w/ a fine tooth comb, and cannot find a nameplate anywhere. I can't find a pic online that matches up either. I asked the people at the restaurant, but they don't know. THANKS!
That is what is known as a "fireless cooker". It is basically a large thermos bottle with pistons and wheels. Note that there is no firebox, nor is there any reasonable way to get fuel into the cab. The locomotive would be charged using a stationary boiler and would run 6 to 10 hours on one charge. These were frequently used at power plants (because they had lots of steam available) and at factories that could not tolerate open fires near the production floor (explosives, chemicals, foods).
There were several manufacturers of fireless cookers. The front of that one looks like a Porter to me but the cab does not. Also Porter often, but certainly not always, enclosed the domes in a shroud like those on the SP GS4s.
