On the New Haven tracks these 77-foot-long locomotives 

 operate on 11,000-volt, single-phase, 25-cycle, alternating 

 current obtained from an overhead trolley system. On the 

 New York Central tracks they operate on 660-volt direct 

 current obtained usually from a third rail, but occasionally 

 from an overhead supply at some crossover switches. For this 

 latter purpose a small auxiliary pantograph is used. Control 

 equipment is, of course, provided for both types of power 

 supply. 



The fully loaded weight is 433,200 pounds, of which 

 272,400 pounds is on the twelve 56-inch drivers. While oper- 

 ating on alternating current, the continuous tractive force is 

 24,100 pounds, and the continuously available horespower 

 3,600. The maximum available horsepower from the six 

 twin-armature, 12-pole motors is 7,600. Slightly different 

 results are obtained while operating on direct current. The 

 maximum safe speed is 93 miles an hour. 



American Locomotive Co. Hudson-Type Locomotive, 1938 



Development of the original Hudson-type locomotives 

 began in 1926 when the New York Central System decided 

 it needed a new type of passenger locomotive to meet the 

 demands of high-speed, long-distance runs. The type was 

 named after the river along which it would run. In late 1937 

 and in 1938, 50 Hudsons of an improved design, built by the 

 American Locomotive Co., were placed on the New York 

 Central. These locomotives, Nos. 5405 to 5454, had larger 

 boilers than their predecessors, had greater tractive force, 

 and were fitted with roller bearings. In addition, Nos. 5445 

 to 5454 were streamlined. 



A nonoperable model (figure 79) in the Museum collec- 

 tion (USNM 313162), gift of the New York Central System 

 in 1947, represents No. 5429. The model locomotive and 

 tender are 2 feet long and are accompanied by a train of six 

 streamlined cars. The entire train is painted silver, with 

 black trimming on the locomotive and tender. Built to a 

 scale of Va inch to the foot, it was especially made for the
