#346 is under repair right now. Work is occaisonally done on 318's very beat-up frame, while a decision is pending on what to do about the boiler, which is repairable, but in bad shape, especially the firebox. Like other posters commented, RGS 20 has some serious problems, as did other surviving RGS power. RGS 42 at Durango is essentially worn-out as well. Doubtful that #191 would ever steam again, with its wrought-iron boiler . However, any worn-out machinery can run again, if there is the motivation (and money) to repair it.
