What is “PAR”? My understanding of various names of “Guilford”. Guilford Transportation Industries owned Guilford Rail Services which owned the Boston & Maine, Portland Terminal, and Maine Central railroads. Operations over these properties is conducted by the Springfield Terminal Railway. The B&M, MEC, and possibly the PTM remain in existance primarily as property owners. The name “Guilford” came from the Connecticut town, which was the residence of majority owner Timothy Mellon and David Fink, who became the chief operating officer. The railroad never operated there, as close as the company probably ever came was having some flyovers by their various air line operations. The Perma-Treat railroad tie plant in nearby Durham CT was owned by GTI, and is now AFAIK owned by Pan Am Systems. GTI is now Pan Am Systems, GRS is now Pan Am Railways. The airline operations, Pan Am and Boston-Maine Airways, have met with rather limited success and I believe the Pan Am operation is dormant. I believe that owner Tim Mellon is a licensed pilot and an airline enthusiast, probably is why he acquired the rights to the Pan Am name.
