Penn Central Railroad underpass US 31

What memories. My father flew B-58 Hustlers out of Bunker Hill Air Force Base in the early 60s. We moved to the base in May of 1959 with the transfer of the 305th Bomb Wing from Mac Dill AFB, Tampa Fla. The wing flew B-47s out of Mac Dill. We departed BHAFB in June of 1964 for Walker AFB, just south of Roswell NM. I have been under that RR bridge a hundred times (before PC built the new one in 1969). As a kid, I used to routinely hang out on the double tracked main line just a few miles east of Onward Indiana, by the Position Light Signals, and watch trains all day. Mostly GPs, and 6 to 8 at a time. We'd count the engines as they went by. As the trains went right by Randall School, I always had to look up and watch out the window...........much to the dismay of Miss Lish. Oh well. What great memories. If anyone reads this and relates, give me an email at gskeney@surfside.net.
