Hey Um Hazel
I gotta ask ya, but have you heard of the last engine idea, Sir. Nigel Gresley had?
Evidently, its suppose to be called LNER 4-8-2 "Mountain" Type Locomotives
However he died, before he ever did start on the blueprints.
I have heard of it! 4-8-2 mountains were more common in other places, but they existed in Britian...well on the 15 inch gauge.Meat Hercules and Sampson of the Romney Hythe & Dymchurch Railway. Built in 1927, their Designer Henry Greenly was friends with Sir Nigel Gresley, and many of his engines follow GNR or LNER practice, so these are a good example of how these engines would have felt.
Further, I made a drawing of a LNER Mountain, based on a sketch by Sodor's Safey Record.
