Hello, let me attempt to decode some of these items on the dispatchers sheet you reference.

The work train listed at the top right of the sheet shows its working limits in the “Between” column, in this case it worked between “Q” and Gypsum. Q is the telegraph call letter for Marquette, KS. If you go down to the section of the sheet for the Council Grove Subdivision, you can find the stations of Gypsum and Marquette. Each of these stations was also the end points of the Saline Subdivision, which paralleled the Council Grove Sub and passed through Salina. Back in that section for Work Trains, it shows this train tied up at Salina, so that tells us it was working on the Salina Sub that day. Engine #1535 would appear to be 2-month old MP15DC built in October 1974.

The only traffic shown on the Topeka Sub that day was the local turn from Osawatomie, which ran as Train #611/#610. #611 departed Osawatomie at 6:45pm with 9 loads, 3 empties and ran west to the junction at Lomax, then north to Topeka. It arrived Topeka at 9:40pm with 10 loads, 3 empties so it picked up a load somewhere along the route. The same crew departed Topeka as #610 at 11:45pm with 3 loads, 14 empties and arrived back at Osawatomie at 3:00am with 5 loads and 15 empties. Power for this job was GP18 410 and GP7 193.
