These are images I’ve collected for the design of the HO scale kits;

I don’t own these digital copies or the originals, and present them here only as a means to help modelers complete their kits.

Information presented here is correct to the best of my knowledge while working through the design of these kits, and thanks to John Tudek for research help & some of the photos collected.

Built in 1953 from the tenders of L-105 class steam locomotives #3703 (250) & #3709 (251), using steam generators sourced from FTs. Equipped with 2 steam generators, plus a 15kw electrical generator / air compressor, and folio-listed capacity of 1200 gallons diesel / 8200 gallons water

Repainted in 1967 into the single stripe scheme, retired in 1987

250 was assigned to Salt Lake City, UT; had additional roof box vents, and added vents to the side doors in the 1967 repaint to address intake air issues, but never had a rear door with ventilation holes.

251 was assigned to Denver, CO; may have had rear door ventilation hole patterns from the initial shopping in 1953, as roof line and side door vents never fitted throughout service life. Front marker light brackets mounted approx. 22” lower than 250.
