introduced on its lines the more advanced 4-4-0, or Amer- 

 ican-type locomotive — the second stage of transition from 

 the old "grasshoppers" and "crabs." 



The replica of the Lafayette has one pair of 42-inch driving 

 wheels, and a leading truck with four 29-inch wheels, al- 

 though the diameters of the wheels of the original were 48 

 inches and 30 inches, respectively. It looks somewhat like the 

 Chicago and North Western's Baldwin-built Pioneer, but 

 whereas it was Baldwin's practice to locate the driving axle 

 behind the firebox, the Norris engine had it located ahead. 

 This feature gave the Norris 4-2-0's greater adhesion and 

 tractive force. The Lafayette replica, with a wheelbase of 

 112% inches and a weight of 29,200 pounds, has a tractive 

 force of 2,323 pounds. Its cylinders have a 9-inch bore and 

 an 18-inch stroke, and it operates on a steam pressure of 90 

 pounds per square inch. 



The replica was built in 1927 for the Fair of the Iron 

 Horse and later appeared at the Chicago World's Fair in 

 1933 and 1934, the New York World's Fair in 1939 and 

 1940, and the Chicago Railroad Fair in 1948 and 1949. It 

 has also been taken several times to the west coast, where it 

 has been used in the filming of motion pictures. In the fall of 

 1955 it was used in northern Georgia in a film based on the 

 story of the famous Civil War locomotive General (see p. 84). 



For many years the replica carried the nameplate William 

 Galloway, this name having been given it shortly after it was 

 built, to honor a famous early locomotive engineer of the 

 Baltimore and Ohio. Today, bearing the correct nameplate, 

 the Lafayette is usually to be seen at the B & O Museum in 

 Baltimore.
