CSXT 6025 leads CSX W001 inspection train as it passes through Mortons Junction at Mortons Gap, Kentucky with Southern Pacific Birch Grove, CSX Florence and TGC2 Geometry Car trailing, as they make their way south on the Henderson Subdivision on July 13, 2021.
Research from a friend reveals: Built by The Budd Company in 1950 as 6 double bedroom, 10 roomette sleeping car 9020 for service on the Southern Pacific’s Los Angeles-New Orleans “Sunset Limited.” The car was acquired by Amtrak in 1971 and renumbered 2696. Converted to Heritage 10-6 sleeper with handicapped roomette in 1980 and renumbered to 2451 and named Birch Grove.
The Car was retired in 1995 and sold to Cincinnati Railway Company. It was upgraded 2002-03 and had a complete interior upgrade in 2005. As of 2014 it was owned by the Cincinnati Railway Company.
CSX purchased the Birch Grove car from the Cincinnati Railway in September of 2020 and from what I find online they plan to use it as part of its executive fleet. They also bought the dome car Moonlight Dome from them for the same reason.
According to Wikipedia: A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the cross level of the two rails. The cars use a variety of sensors, measuring systems, and data management systems to create a profile of the track being inspected.
One of the earliest track geometry cars was Car T2 used by the U.S. Department of Transportation’s Project HISTEP (High-Speed Train Evaluation Program). It was built by the Budd Company for Project HISTEP to evaluate track conditions between Trenton and New Brunswick, NJ, where the DOT had established a section of track for testing high-speed trains, and accordingly, the T2 ran at 150 miles per hour or faster.
