 same report is not dissimilar to the section of standard 66-pound rail 

 now in use on the Chicago, Burlington and Quincy and several other 

 railroads. Fig. (51 is from a drawing in the collection.

English engineers had, in the mean time, given considerable attention 

 to the jQ_ rail (or ; 'box rail," as it is sometimes called) both in England 

 and in Canada. 



Imported XI rails were laid as early as September, 1835, on the 

 Wilmington and Susquehanna .Railroad. In 1845 a modification of the 

 XI rail was laid on the Drogheda Railway in Ireland — the rail being 

 compressed inwardly at the bottom until the inside comers were made 

 to touch. In America a small quantity of a similar rail was manufac- 

 tured at the Mount Savage rolling mill, called "hollovv rail." This 

 was done by heating the rail after it had been rolled to size and passing- 

 it through a set of rods designed for the purpose.* 



A cross-section of this form of rail in use on the Great Western Rail- 

 way of England is shown in Fig. 65, while in Fig. 60 a cross-section
