Here is a photo that I took in June 2006. It was taken in Cajon Pass just south of Sullivan's Curve. It kind of sums up the merger of the Santa Fe and the Burlington Northern with the NEW on the point and the OLD following.
The 4th loco is a Norfolk Southern. You see all kids in the Pass from CSX, CN once in a while you can see a freight with three or 4 different roads and not all from the BNSF.
