I don't have much choice, as NH and PRR were practically "sister roads" in western CT and around NYC throughout the 20th century. With few exceptions, all Washington/Boston passenger consists were mixed with equipment from both roads, and the New York Connecting Railroad (the Hell Gate Bridge section) was jointly built and owned by both roads. PRR freight equipment had the second largest presence in CT, after NH — even more than the other New England roads.
I like Pennsy, but I don't need to have everything-PRR that comes to N. Freight and passenger equipment, very little motive power, no cabooses. I own GG1s, but two have been repainted CR and only 4935 Blackjack will remain in Pennsy livery (for pulling Amtrak consists). Most of the others are being stockpiled to be used to power eventual scratchbuilt EP3 and EP4 electrics. I have a Trix K4 that I may repower someday and use as CR's excursion power. And all PRR-heritage cabooses I have are decorated in CR livery.
I model 1956 and 1980, so no CK scheme on the H30. N&W equipment didn't have a large enough presence in western CT to warrant me having an H30 in that scheme. I also have to watch the number of cement hoppers in general so that it stays close to the proper percentage of the freight fleet. And they were a rarity by 1980, so probably no CR scheme for me either.
