Kelly nice work. You could be right about the RGS turning the Tires, as crazy as it sounds. Or could it have been for use on the Montezuma Lumber CO track's?
According to the CRRM book Loco 346,
rebirth for the 21st century
"
by the beginning of 1944, No 346 was showing signs of wear and tear. Rio Grande Southern anticipated that the loco would soon need new rod brass, some shoe and wedge work, and the driver box lateral taken up. But 346 kept right on working, and RGS reports for April showed that ran a total of 1,056 miles. of which 840 were in freight service and the remaining 216 were in helper duty. The engine was out of work in August and September and received new flues on October 17, 1944. The running gear was attended to at the same time. In November, the 346 was back in operation on the RGS.
After reading this, I guess I should rethink what I said in my other post. While it would make more sense to properly repair the lateral problems, the RGS might have seen it being cheaper to just turn the tires and give 2 and 3 a small flange to keep them in line.(taking material off tires is cheaper that buying brass for wear plates, and paying a welder to weld on the frame)
