Thanks, Jimmy. My book starts the next day, Nov. 20. Engine #7 does not reappear until Dec 11, with Westbound Train No. 71, and the two trains associated with the Westbound runs to Dillon, trains, No's 89 and 90. The next day, Dec 12, #7 returns Eastbound to Denver on Train No. 72, and the associated Eastbound runs to Dillon and back, Trains No.'s 87 and 88. Looks like Engineer Stein on #7 with Conductor Smith.
