Lima Northern-Type Locomotive, 1937

A black, red, and orange nonoperable model (figure 77) in the collection

represents the Southern Pacific Co. _No. 4410_, the first of the many

such streamlined 4-8-4, or Northern-type, steam locomotives built for

that line. This model of _No. 4410_ and its tender, about 27 inches

long, is built to the scale of ¼ inch to the foot. The gift of the

Southern Pacific Co. in 1937, it was made early in that year especially

for the Museum’s collection (USNM 311340).

The first group of this type of streamliner, which was the conception of

George McCormick and Frank E. Russell of the Southern Pacific, was

completed by the Lima Locomotive Works in January 1937. The first run

with one of these streamliners was made on March 21 with the “Coast

Daylight” passenger train between San Francisco and Los Angeles.

Of the total of 50 essentially similar locomotives of this streamlined

class, the Southern Pacific still had 49 in November 1954, only _No.

4414_ having been authorized for scrapping. At that time, these

locomotives had averaged approximately 13,000 miles a month since being

placed in service, although many had completed over 15,000 miles in

particularly productive months. The earlier ones, represented by this

model, developed 4,500 horsepower at 55 miles an hour and had a top

speed of 90 miles an hour, although 75 was the highest allowable

operating speed. They were able to maintain a 9¾-hour schedule between

San Francisco and Los Angeles.

The locomotive and tender are 108 feet long, and weigh 835,000 pounds in

operating condition. The fuel is bunker type C oil. A boiler pressure of

250 pounds per square inch is employed. The cylinder bore is 27 inches,

the stroke 30. The eight drivers are 73 inches in diameter, and the

driving wheelbase is 20 feet. The later streamlined 4-8-4’s of the

Southern Pacific develop 5,500 horsepower at 55 miles an hour, and

operate on a boiler pressure of 300 pounds per square inch.
