Western Railway of Canada, is shown. Both of these figures are from 

 drawings in the collection. 



The XX rail was in use in several of our Southern States during the 

 war of 1861-'C5. 



It was found that the _Q_ rail was almost certain to fail when laid 

 on cross-ties, and for this reason roads, notably the Nashville and Chat- 

 tanooga, that used it always favored the superstructure with the rail 

 bearing on a longitudinal stringer instead of a cross-tie.

 Barlow's "Saddle-Back" Rail, 1856. Laid Without Sutpobts. 



(From a drawing in the U. S. Nation.il Museum.) 



Fig. 67 is from a drawing of Barlow's "saddle-back rail" in the col- 

 lection. This rail has an extreme width of 13 inches and were designed to 

 dispense with the use of woodeu ties or stringers iu track construction. 



The rail was laid in broken stone with tie bars 10 feet apart. Nine 

 hundred miles of this type of rail were laid in England prior to 1858, a 

 mile or two also were laid on the Reading Railroad in the United States. 

 "Between 5 and 6 miles of this rail, closely riveted together, were laid 

 in England in 1850 and were iu use for several years without experi- 

 encing any difficulty from expansion."*
