I remember when High St. and Rogers Street had flashers, it was the late 90's early 2000's when I last saw them. I know about the B&B but didn't the B&L/B&M make this a continuation of the Lexington Branch? When I was a truck driver for a local carrier back in 2013-2016, I was in Iron Horse Park very frequently, picking up and dropping off for the various companies and never once did it appear the tracks were used, the rail was always heavily rusted with no sign of a wheel ever touching them, no flange marks in the crossings and during the winters the snow was never disturbed, yet it was 50/50 to see a train moving about in the park. I average 1 to 2 visits a week during those days.
It takes real skill to choke on air, fall up the stairs and trip over nothing. I have those skills.
