I got called for another dog catch. On duty time was 7:46 pm Mountain Time. We took the van out to West Berry to dog catch the "S OMASCO." Then we had to go and get on a unit train at Franconia. It had only one engine, 5 cars ad a crew that sprayed the sidings. We were limited to 30 MPH. We knew that we would have to yard the train afterwards and the spraying crew said it woud be better if we coud park the train on a track where they could bring their truck up to it. We wenti nto the South House extension. There wre no cars in there. I threw the switch, dropped the derail, and rolled my train by. I had to restore the derail, reline the switch, and tie one brake. We were done. I'm projected to go out around 11 pm tonight.
