CS Class: A-3

Drive Wheel Diameter: 81 inches

Cylinders: 16&27x28 inches

General Notes:

a.	UP 21-35 were built as Vauclain compounds; not rebuilt to simple prior to being retired 1921 and 1923.
b.	From an old issue of Railway Age: The Union Pacific is one of the group of railroads made up of the Southern Pacific, the Oregon Short Line, the Leavenworth, Kansas & Western, the Oregon Railroad and Navigation Company, and the Chicago & Alton, known as the Associated Lines. The Union Pacific have recently obtained from the Baldwin Locomotive Works some 4-4-2 engines of the 4-cylinder balanced type for fast passenger service. One of these interesting engines was exhibited at the Master Mechanics' convention at Atlantic City this year. The design conforms as far as possible in detail to the common standards adopted by the Associated Lines. The engine is built with cylinders 16 and 27x28 ins. The high pressure cylinders are inside and the low pressure are outside. The crossheads are of the alligator type, while the inside ones run in four guide bars. The main valves are of the piston type, 15 ins. in those of the cylinders. The valve gear is the Walschaerts motion, actuated by cranks on the main drivers. The driving wheels are 81 ins. in diameter and are placed so close together that their flanges almost touch. The driving wheel base is 84 ins. The rigid wheel base is 15 ft. 9 ins., which takes in the carrying wheels at the back, while the total wheel base of the engine is 27 ft. 10 ins. The weights carried by the various sets of wheels are about 53,000 lbs. on the engine truck, about 46,000 lbs. on the carrying wheels, and about 110,000 lbs. on the drivers, making an estimated total weight of 209,000 lbs. With a boiler pressure of 200 lbs.,the calculated tractive effort of this engine is about 28,400 lbs.
