The 4 motors of the combined Job 102/103 are screaming as they try to bring the 21 loaded cars of marble up the wet grade towards Jasper. 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. But boy, was I proven wrong, because from Talking Rock to Jasper, these 4 motors legitimately put on one of the best shows of noise I've ever gotten to experience. It was so good, that I put my camera away away at the next spot, hit record on my phone, & just enjoyed the show because I didn't want to be distracted from enjoying it despite knowing my video would never do it justice. Also, I'll go ahead & admit it... I was foaming quite a bit during all of this.
