PRSL,
Interesting info. It is also interesting to see only 3 loco's live and one of those being the 476 in Durango for the Silverton. This must have been a slow period. With the 492 and 493 getting major overhauls--probably class 4 it is easy to see why they were among the last in regular service over Cumbres. Great info-keep it coming. Thanks.
