Sizemore,
Unfortunately that story is about a different class of engine. The loco pictured doesn't have angled pistons and the D-1's mentioned in the story never left Baltimore. This loco, as Chris mentioned, is in Cincinnati. In the B&O power book, it is classed as D-odd. On the N.E. Rails site where the picture is available it is classed as a D-3. The other D-3 pictured is more conventional.
Being that it is converted to a tank loco, it looks like the shop thought the easiest way to make a coal bunker was to close up the windows and fill the cab full of coal. It looks like it has a chute or opening in the top to load it. It would sure make firing the loco easier, maybe as simple as opening a door or chute from the bunker above the fire box and letting some coal fall from above.
I wish we could fid more history on this as it is definitely an odd duck.
I have no clue Chieftan, I just googled B&O and 1120/320 figured it could have been a starting point. I mean I can't read I have a real job ya know! ;D
