I do a lot of driving for work and happened to stumble upon this train today in Ayer, MA on the Pan Am (the former Guilford Rail System) main line. I have never seen the Federal Railroad Administration Office of Safety train before...not even in photos, let alone in person. Interesting to say the least!
Does anyone know the primary purpose of this train? Does it carry a team of people who respond to/investigate rail accidents? Or does it travel around on our nation's railroads to inspect for safety violations? Or something else? Please educate me!
