The Burlington also rostered a fair amount of power with Belpaire fireboxes in the early years of the Twentieth Century, particularly on some of its Mogul (2-6-0) and Atlantic (4-4-2) classes, but this was before it was brought more directly under GN control, if memory serves me correctly.
I think it's also worth recognizing that the J-1 Texas (2-10-4) locomotives, the only really successful class of later PRR steam power, did not feature a Belpaire, but this was due to the War Production Board-mandated copying of a 1929 Lima design built for the C&O. As with the NKP's Berkshires (2-8-4), and all of N&W's later power, the decision to standardize on a limitied number of designs paid substantial dividends.
