That is an awesome engine! I wish I had 1/10th of your talent. Being "talent challenged" I opted for a couple of the Bachmann Spectrum 4-4-0s...which I still have to letter. My latest project is a near copy of the 1899 roundhouse in Hopewell Junction, NY (on the Newburgh, Dutchess & Connecticut RR). The only kit I found that approximated this structure was from Faller (yes, I checked all the laser-cut kits and, no, I am not interested in scratchbuilding). The Faller kit is clearly European, so there was lots of kitbashing needed. I used siding from Paper Creek Models and slate shingles from Northeastern Scale Lumber. Considerable effort was expended in back-dating this structure to the late 19th century. All that is required for completion is to "shingle" one more stall roof and weathering the whole building. Thanks for sharing those excellent pictures of your locomotive. May I suggest some B.T.S. rolling stock to match it?
