There was a small error on the Buffalo/Central Terminal shuffle diagram. It showed a Niagara Falls-GCT 12-6 being relayed to New York on 26. Try #8. The only times a car (or cars) were added/ dropped at Buffalo after it was dropped as a passenger stop (1938, before the stream liner 25/26 roll-out) was during and immediately after WWII, when the sheer volume of mail being moved forced NYC to add a third RPO to the trains at Buffalo in both directions. When 25/26 had two RPOs, both ran all the way with one car handling NY-Chicago through business,the other the intermediate business. A sadly departed NYC retiree told me that during the war time holiday seasons,plus 1945-6 ,mail volume was such that the previously unmentionable step of adding a third RPO to the Centuries was carried out. They grabbed any RPO available,so the all-streamlined look was -temporarily-dropped so that G.I. mail could be moved. Sadly, by the 1946 holiday, the standard pair of RPOs could tackle the traffic. A decade later the business traveled in a single RPO and late in 1967, when the postal service dropped the CHI & NY /NY &CHI RPOs, it ended the “life” of the Century. P.M.Benham,Kenmore NY
