I didn't run on 9/23. On Tues. 9/24, I ran 497 on a helper with 488 and 13 cars. 488 went on east.
I didn't run again until Sat. 9/28 - again a helper turn with 497, but this time middle engine on a triple header with 463 leading, 488 as road engine - 23 cars 521 tons.
If our usual rotation held, on Wed. 9/25 497 would have run as road engine east to Antonito and returned on 9/26. On 9/27 she would have been in the shop for inspection, then out on 9/28 as helper of the 3-engine train on 9/28.
Seeing the blow up of the shot, might not be me. I always wore my black half sleeves. Might be Tom Atkinson. Also, the consist I brought back on 9/22 was 17 cars, a lot more than the pic shows (11 cars).
More mysteries.
