CLASS K * ATLANTIC * 4-4-2
Ten class K-1 Atlantics (1700-1709) were built by Baldwin in 1906 to provide Great Northern with a light, fast passenger locomotive. The 4-4-2’s originally were constructed as balanced compounds, having 15/25 x 26-inch cylinders, 73-inch driving wheels and operating on 200 pounds of saturated steam. Each engine weighed approximately 104 tons. Stephenson valve gear operated the piston valves. Tenders carried 8,000 gallons of water and 13 tons of coal. In later years these engines were made simple (21 x 26-inch cylinders) and superheaters were applied. As late as 1925, the K-1 powered the Oriental Limited over level districts.

The glaring differences are the placement of the domes and the bell, the spoked wheels, and the tender. The domes and bell I can live with, I doubt that I will ever find spoked wheels, so I’m not going to worry about that either. There is only a slight difference in the tender. I think that I’ll just leave it alone, with the exception of finding some metal wheels. Gary Raymond has those.
