Best guess I have for a date is August 4, 1997. There are too many holes in my notes to pin it down with certain. What is interesting is all that seems to be running is 463, 487, 488, 497. No 484 or 489. My call book for that summer shows 484 running early in the season, last day I was on her was May 26 as helper for 488. 489 does not come into service until September. First day I ran her was Sept 4 on a light doubleheader of 9 cars, 260 tons with 488. Form the laundry list of repair items I noted, it probably was her first trip.
