The combined Job 102/103 heads south by the Horse Farm (MP 422) with a load of marble & GP18 8705 on the point. With 21 loaded cars in tow, one of the bigger trains to have come south from Whitestone, the 4 engines, with 2.5 of them being 567 prime movers (4631 has 645 power assemblies), I knew I would be in for a good show with this rather literal "Throwback Thursday" of a power consist that harkens back to the days before Patriot Rail. Little did I know though just how good of a show was waiting for me between Talking Rock & Jasper.
