A new addition to my HOn3 layout, the new Blackstone Models “Long” caboose 0540 from the Denver & Rio Grande Western. Prototype belongs to a series of five cabooses re-built between 1912 and 1925 from older (1880s) cars. My model bears the “Royal Gorge” Herald and is slightly factory-weathered, . #0540 was the last caboose to operate on the D&RGW. It is now preserved on the Durango & Silverton.
