“Where There’s Smoke…” A CSX track geometry train, symbolled as a passenger extra, kicks up fresh ballast fines as it approaches the intermediates at Harberson Walker* [sic] at mp 50.4 eastbound on CSX's Philadelphia Subdivision. The train consists of not-exactly-pride-of-the-fleet CSR/CSXT GP40-2 6239, power car, and TGC-2.
*so named (or misnamed) ostensibly because of the signal’s proximity to the Hile Plant of Harbison-Walker Refractories, located just 100 yards (compass) northwest.
