Rail Grinder
I got to spend some time up close with this rail grinder as it worked back and forth over several sections of the rail. As seen here, it is traveling West on the Pittsburgh line, following the larger rail grinder.
My understanding is this one works switches while the larger one works the main track itself. Either way, when they are done they leave a nice swirl pattern in the rail head. They also had several folks following in high-rail vehicles to inspect the work.
