Description
The great French steam engineer André Chapelon produced diagrams for a range of modern steam locomotives of various wheel arrangements to cater for all SNCF traction needs after World War 2. Only the 2-10-4 got as far as detailed drawings. Using these, and other sources of reference, I produced this painting of the projected 4-8-4 and one can clearly see the combination of French and American practice visually expressed. What a locomotive this would have been!
