On May 13, 1980 Extra 7284 waits on the main line at the station for an empty train (Extra SP 8729) to take the siding. Both trains serve the power plant in San Antonio. Once the empty train is by, the agent at the former Rock Island yard office gives the signal to the loaded train to proceed across the old Rock Island mainline. Dalhart is at milepost 417. Notice that the BN train order operator has put his train order signal back to red after the northbound train had passed.
