Figure 60. — Memnon as it appeared shortly after January 1 , 1 884, when it had 

 been renumbered "13." A few years later it was given back its original num-

The original specifications, as set forth in the B & O ad- 

 vertisement, called for a locomotive weight not to exceed 20 

 tons (of 2,240 pounds). According to J. Snowden Bell, the 

 weight amounted to about 52,000 pounds at first, but 

 changes reduced it to about 47,000 pounds. It would be 

 interesting to know what parts, unnecessary enough tojustify 

 their removal or so sturdy that they could be drastically 

 lightened, were involved in changes that reduced the total 

 weight by 5,000 pounds. Today, the unloaded weight of the 

 engine and tender together is 74,700 pounds. The tractive 

 force is 8,580 pounds. As was true of the Baldwin-built 

 Pioneer, the cowcatcher of the Memnon was not installed 

 originally. 



This class of locomotive, which burned bituminous coal, 

 introduced to the B & O the grate having a rocking bar in 

 the center, with fingers on each side that interlocked with 

 projections on fixed bars in front and behind. The rocking 

 bar operated from the footboard. 



The Memnon has appeared with other engines in the his- 

 toric collection of the Baltimore and Ohio Railroad at many 

 expositions, fairs, and railroad pageants. Its permanent home
