Many of us love what are known as Fallen Flags Railroads and their trains; they no longer exist but we have fond memories of them, often from our childhoods.
I also believe that most of us remember the TV series from the late 1950s and early 1960s known as The Twilight Zone. When I was a 5 to 10 year old kid, my parents watched this show, but I rarely did because the spooky music and eyeball flying through space at the beginning of the show terrified me. LOL.
My reason for mentioning the Twilight Zone is because I vaguely remember an episode or two in which the characters go back in time.
That's what we can do here - go back in time and relive our nostalgic feelings for the now fallen flag railroads and trains of our past or our loved ones past.
