Found this while looking at the NFL pregame bushwa (can't cuss on Trainboard ) http://mptv.org/Trax_main.htm This is the website for Tracks Ahead- for us North American railroad nuts, it also has a list of the PBS stations that carry TA. Also, check out the merchandise section.
I believe I had this link on my old computer and lost it when moving stuff to the new one. Thanks for posting it for us.
