Congratulations, Carsten Weye! Indeed, it is the San Louis Central. Home for all 2 units they have! Last time I was there, years ago, they had an EMD SW unit and a rarely used GE 70 ton. Think they also do repair work on their own fleet of cars. Want to go back down and check things out again one day. They've got an interesting operation there.
The SLC owns two locomotives. An EMD SW-8 and a GE 70 ton. The line is 13 miles in length. Running from Sugar Junction to Center, CO. Hauling grain, potatoes and fertilizer. Also a car owner, mainly reefers and boxcars. This comes from Wikipedia.
