Model of Cast Edge Rail, 1802. Invented by Mr. Wyatt. 



This rail was used on the railway at the slate quarry on Lord 

 Penrhyn's estate near Bangor, North Wales. The general shape of 

 the cross section of the rail is a hexagon. At each end a dovetail 

 block, 2 inches long, is cast at the bottom. This is slipped into a 

 chair which had previouslj'- been attstched by a bolt to the wooden 

 or stone support. Cat. No. 180,205 U.S.N.M. 



Model of Cast-iron Tram Rail, 1803. Used on the Surrey Railway, England. 



This rail is said to have been made " with flange higher in the 

 middle and a nib under the tread to add strength." It has a rec- 

 tangular notch, half square in the ends, the joints being completed 

 by one square-headed iron spike, which is countersunk. 



This rail, although an improvement, failed to give general satisfac- 

 tion, and in a very short time became obsolete.

Model of Cast Rail with Concave Top, 1803. 



This rail, patented by Josiah Woodhouse, is fastened to trans- 

 verse crossties by bolts slipped into slits through the base. It was 

 to be used also by road wagons and to be embedded in common roads.

Among the most interesting relics in the collection are two of the 

 cast tram rails, 3 feet long, from the track extending from Pen-Y- 

 Darran Iron Works to Navigation House, Abercynon, Wales. These 

 rails were a portion of the original track upon which Trevithick's 

 first locomotive ran in 1804, and are the gift of J. W. Widdowson, 

 Esq., London and Northwestern Railway, England. 



Model of Cast Tram Rail, Designed to be Laid Without Bolts or Spikes. 



Charles Le Cann, of Llannelly, Wales, in 1808 received a premium 

 of twenty guineas from the Society of Arts for the invention of 

 this rail, which was ingenious in construction. Projecting pins, 

 pyramidal in shape, are cast on the bottom of the tram rail at the 

 points where the stone supports come under the rail, the joints being 

 dovetailed into each other; the need of any other form of joint 

 fixture was thus dispensed with. These rails are about 5 inches 

 wide and weigh 42 pounds a yard. Cat. No. 180,211 U.S.N.M.
