I was wondering if the mileages on the Penn Division had their own mileage series, due to the joint Erie track, or if they continued from Albany, down the Susquehanna Sub?
The D&H track on the Penn Division had mile posts with two numbers - miles from Albany on one side, and from Wilkes-Barre on the other. The "magic number" was 211, so the numbers on each milepost added up to 211. The D&H bought the Jefferson Branch from the Erie about 1955, and I believe I remember that the Erie mile posts existed until then, with miles from Lanesboro (on the Erie) to West Carbondale, then picking up the D&H miles again to Wilkes-Barre on the D&H. When the D&H bought the Jeff, they left the Erie mile posts in place, but placed A and WB mileage numbers on them so there was a mileage equation (long or short miles) at Jefferson Jct. and West Carbondale. SW Cabin at Nineveh Jct. was A-188.2 and Wilkes-Barre was A-211.6.
The Susquehanna Division used Albany and Binghamton mileage numbers. The magic number was 143 (via the Albany Main from Kenwood Jct to Delanson).
