In better days, Lewisburg had two railroads. The Reading operated two distinct routes between Pottsville and Williamsport -- one via Catawissa and Danville, which got most of the freight traffic due to easier grades, and one via Sunbury and Shamokin, which got the passeneger traffic, plus a fair amount of local coal-mine runs. The latter also had some severe grades in tha vicinity of Gordon, Penna.
Thr Pennsylvnia on the east shore of the Susquehanna saw four daily passenger moves, plus about twelve freghts, until the late 1960's. A bracnh to Bellefonte diverged from the PRR main at Montandon, crossed the river and the Reading at an interlocking tower designated UR. As traffic fell off, the line was cut back to Mifflinburg, then sold off as the West Shore.
Incidentally, the West Shore, North Shore (Sunbury-Berwick), Lycoming Valley and several other spinoffs operated by the Robey Group are all managed from Northumberlad, about ten miles downriver from Lewisburg. And the former PRR Wikes-Barre Branch, now under joint NS/Cpr operation as the Sunbury Line, has witnessed a substantial increase in activity since its rehabilitation in the late 1990's.
All in all, not a bad neighborhood for a railfan.
What a revoltin' development this is! (William Bendix)
