CSX's Sand Patch Grade in 2014: Part 4

In our fourth and final part of my first video coverage of CSX's Sand Patch Grade, we'll shoot a number of trains along the east slope before returning down the mountain to Cumberland. There, we'll end our Keystone Sub coverage the same way we began by shooting a K055 with BNSF power at Viaduct Junction. Finally, we will see some bonus footage at Mexico interlocking on the east end of Cumberland Yard. I mentioned this in Video 1's description, but once again a big thanks to o00o00ozy for providing transportation and location expertise for the entire trip. It's been a while since I've been out railfanning on the east coast, so this was a great way to get back into it!
