I skimmed through the video but didn't catch any mention of a re-designed boiler such that it would be semi-rounded in at least a couple areas. My buck stops there. Even the famous 700e Hudson of 1937 had a semi-rounded boiler on the underside.
Paul, the early 700E’s really don’t have much at all of a rounded or even a semi rounded boiler. They’re U shaped like the majority of die cast models. Only a very slim section of a 700E boiler is rounded, ..and that’s ahead of the saddle, in the smoke box area. Kline’s scale Hudson has a section fully rounded ahead of the saddle, in the smoke box area as well,…..you can’t have a fully rounded or even semi rounded boiler with all the electronics and smoke units they cram in these machines,…….Only brass locomotives have the most “rounding” ….clear back almost to the cab, with just a slit for any gear box shaft, etc,…..Lionel’s later run Legacy J3a Hudson shares the same idea of a small section ahead of the saddle that’s rounded ….just like the Kline ….you’re not going to get a rounded boiler or even semi rounded, ….I don’t hardly call any of those die cast models rounded or even semi rounded, ……..The ploy that this is semi rounded is a far reach IMO, and more than likely follows suit of the Kline & the latest Legacy J3a,….
