A 41 year old SD40-2 (ex L&N 1261) rolls by the newest power on CSX. The CSXT 2437 is working the hump at Selkirk as it shoves Receiving Track 2 past the locomotive service area which contains CSXT 3257 with CSXT 3262 behind it. The 3262 is paired with CSXT 3264 which is out of sight to the left. This was the first day for CSX Tier 4's at Selkirk.
