I'm looking for documentation on trains 530 and 531 that operated the Creek and Sherman Subdivisions in the late 70's up to the merger. They appear on the schedule in ETT No 4, dated April 22, 1979, but they weren't included in the big bundle of operating data sheets available in another post. By chance does anyone have the ODS for this pair of trains?
One of the ones I have downloaded on my computer has the No 530 but it's from 1966. That isn't exactly the same time period your looking for, but it looks like the same route, Fort Worth to Cherokee via the Creek and Sherman subs. All the ones the later ODS sheets that I have don't have it. All the ODS sheets I have I have found online, I don't own any ODS books.
Actually scratch that, looks like there was one more I have downloaded I didn't open from 1975 and it has them. I'll attach the file here, again not mine I downloaded it either on this site or somewhere else, I don't remember where it came from.
