I came across this looking for something else. I guess if I was going to change my era 1970 would be interesting. Watching this video, All the passenger trains start out pure. As the video plays, you start seeing mixed from the BN merger and you also see Penn Central with rolling stock and engines still in PRR and NYC. The only pure sets were ATSF, GMO IC, and Milwaukee rd. At the end of the passenger section you start seeing a complete mix of cars and engines to include some cars that had been repainted with AMTRAK Livery. Freight was the same way as footage showed CB&Q at the start, Then the multi colored consists with BN/GN/CB&Q/NP Some had the new BN reporting marks, some didn't. Same for Penn Central PC/NYC/PRR. One thing I noticed was that there were a lot of 40ft PS1 and AAR box cars still in service. Same as for markings CB&Q for example. Even thought they had gone to Chinese Red, a lot of the 40 and 50 ft cars were still in mineral red and still had Way of the Zephyr and Everywhere West on the sides. So what do you think?
