NS 202 (CSX Z359-26) is coasting at the bottom of the grade at Wauhatchie Pike on the final leg on the CSX Chattanooga Sub. The haulage rights freight is running on an medium-clear signal where 202 will get off the CSX main onto the connection track, and back on the NS trackage for Chattanooga. In a much different time this section of railroad was notorious for being a bottom neck for traffic on the CSX Chattanooga Sub main for train that was by-passing Wauhatchie Yard, and for NS traffic as well. Between control-point Wauhatchie and, Wildwood with two and half mile of single track, and a Koch Feed Mill that was serviced along this section of railroad with problem such as the Koch Job using the main or the occasional CSX run through massive freight swapping on the main could hold up traffic from minutes to even hours at a time, thus the main 2 track was built years later. In a worst case scenario if CSX needed access to the W&A main, they would send traffic through the Yard to the south-end at Lookout to keep their traffic flowing, not so much for NS traffic.
