CSXT GMS-2, running as W002-22 heads north as they approach the location known as Romney, just south of Nortonville, Kentucky, on the CSX Henderson Subdivision, on July 22nd, 2025.
From what I found on the Web: G-Gauge M-Measurement S-System is one of 2 such vehicles on CSX. It puts artificial stress in different directions on the rail to simulate a passing train and measures the amount of deflection caused by said stress to determine if tie, spikes and anchor systems are functioning as needed.
Tech Info: Nikon Z6ii, RAW, 70-300mm, @210, f/5.6, 1/1250, ISO 560.
