signal.<\/p>\n\n\n\n<p>Curiously, Reading continued to install new Hall Discs years after perfection of the electric three-position semaphore.<\/p>\n\n\n\n<p>A few of Reading\u2019s Halls survived into the diesel era.<\/p>\n\n\n\n<p>Reading &amp; Northern, which operates significant sections of the old Reading Company, installed this recreated Hall Disc near its Port Clinton, Pennsylvania offices in homage to Reading\u2019s classic signaling.<\/p>\n\n\n\n<p>In December 2014, I made this sequence of photos using Pat Yough\u2019s FujiFilm XT1, on a trip to photograph R&amp;N\u2019s 4-6-2 Pacific number 425 that was running Christmas trips to Schuylkill Haven and Minersville.<\/p>\n\n\n\n<p>Now that I\u2019ve endeavored to recreate the Reading Company in HO Scale, I\u2019ve stumbled upon a quandary: How to make operating scale models of the antique Hall Disc signal?&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\"
