"DOT Geometry Over Noroton River
The Metro North/ Department of Transportation Geometry Train crosses the tiny Noroton River while heading down the New Canaan Branch in Stamford, CT. The train is tasked with traversing all of Metro North's mainline track while the middle coach, DOTX 221, collects geometry data reports for the FRA and US Department of Transportation.
The DOTX 221 is an ex- Canadian National Pullman coach painted in Pennsylvania Railroad colors equipped with a track geometry measurement system, a rail profile measuring system, and other state-of-the-art instrumentation for conducting railway research.
