Ross,
I know up until 1981 it was stored servicable along with the 493 inside the Alamosa Roundhouse--so it was never in bad condition. It was also parked inside the Durango roundhouse for quite sometime at the museuem. I doubt the D&S would ever rebuild her or any other 37, but it could be rebuilt and put into service just like every other 37 out there. It is just a matter of money to get them restored. I believe the 492 has the newest boiler of any surviving D&RGW ng locomotive as she had a new one installed in 1948. Bottom line is the D&S doesn't like them because of their experience with the 497 which had tracking issues with her pilot truck--I think that another 37 would provide different results, but who know's for sure. I for one would love to see them all restored and running on the C&TS someday.
