Dear Alan, have many thanks for your essay about steam-efficiency. But I disagree kindly about [quote user="Alan Robinson"]  it (The A1) was perhaps the greatest steam locomotive ever constructed and was the pinnacle of steam design. [/quote] From a efficiency level, yes (the D&H achieved ~12% with their 2-8-0, also) - and I believe the Americans had all the knowledge to built "modern" steam locos, already. But, except those "test-beds" nothing appeared in real live. Simplification was better, in my eyes. This is why many people feel, that post '40 American steam-locomotives could not be developed further in a practically way. With their casted, integrated roller-bearings machine-beds, free steaming boilers, they were rugged, reliable and competitive, making real money on the road. Keeping them running in their most likely speed-range, they could have shown nice efficiency levels, also. Cheers lars
