I got them both in one shot. Though you're probably more familiar with the EJRR #: 67 and other big red units, there is one other unit that also provides switching services for Chem South. It's the little yellow Trackmobile on the left. While the big locos bring tank cars into this area, the Trackmobile usually sits inside the fence and shifts them around on the tracks. It was nice to see this little critter on the outside and, even more nice to see them both posed next to each other right by the gate to Chem South.
