Norfolk and Western Class Y7

The Norfolk and Western Class Y7 was a proposed locomotive class of 2-8-8-2 steam locomotive Mallets for the Norfolk and Western Railway.https://cs.trains.com/trn/f/740/t/225489
==Ideas for the design==
The end result was that the Class Y7 wasn't supposed to look like the rest of the N&W Y-Class 2-8-8-2s, it was instead meant to resemble the DRGW Class L-131 2-8-8-2s but it would have a delta trailing truck has a relatively long side frame it was also meant to have a higher boiler pressure at up to 300 psi (2.1 MPa), it would also have air-compressors mounted on the front, as well as having the same cow-catcher design from their Class A 2-6-6-4s.
==Why wasn't it built?==
The reasons to why the Norfolk and Western Class Y7 wasn't built was that when the 1940s and 1950s had came, steam technology was considered as old-school, Diesels were rapidly taking over steam locomotives in America, the idea/notion of investing another steam locomotive wasn't a good idea, so the Norfolk and Western Railway had wounded up buying a bunch of diesels, as did pretty much every other railroad company.
