Chicago, St. Paul, Minneapolis, & Omaha Ry., Class "I-2" 4-6-2 #385

Photo taken, Spooner, Wis. Circa 1952

The #385 is seen here in the Spooner roundhouse in the one stall reserved for a standby passenger engine, the other 7 stalls in that section of the roundhouse were reserved for the Ja's. #385 was not nearly as common a sight at Spooner as #386 was. The day I took this photo was the last time I ever saw a passenger engine of any type on the Omaha RR. Although I can't verify it, I was told that #385 was later inadvertently destroyed when someone assumed that it was full of water when in fact it was dry, and built a fire in it. Using the roundhouses direct steaming facilities, the fire was brought up to such a high heat that the red hot crown sheet fell off the staybolts and collapsed down onto the arch tubes. A sad end for a faithful servent.
