1 44 Hudson mid Mohawk Rail Road. 



inches stroke. To these is attached the apparatus for hauling up 

 the cars which will presently be noticed. 



The road then proceeds North Westerly up to the head of Lydius 

 Street to strike which, it takes a curve of four thousand feet radius, and 

 passes over two heavy and high embankments, and through some 

 deep cuttings near the alms house. 



From tlie head of Lydius Street, (where the travel at present ter- 

 minates) it proceeds in the same direction, crossing the heavy en- 

 b^nkment, called the Buel viaduct, ascending a plane for about three 

 miles, of one foot in two hundred and twenty five. Afterwards as- 

 cending by two other planes at- different points, and crossing several 

 waterways, upon enbankments it proceeds to the Schenectady sura- 

 rait. There are in all six principal embankments. 



About four miles from Schenectady, there is a curve in the road, 

 (radius tv^^enty three thousand feet) which with most people passes 

 unnoticed. Just at the summit is a smaller curve with a radius of 

 one thousand one hundred feet. Besides the plane last mentioned, 

 there is another of three miles, where the ascent is one foot in two 

 hundred and seventy, and another of one mile and a half, where it is 

 one in four hundred and fifty feet. The descent from the Schenec- 

 tady summit, to the level of the Hudson is three hundred and thirty 

 five feet. At this point, to which we have in imagination conducted 

 our readers, a beautiful view is obtained of the Canal, the Mohawk 

 river, and the ancient city of Schenectady. A double stationary engine 

 is placed here, and may thus be described. In the cellar of a house 

 which is built on stone foundations across the road, and on the North 

 side are placed the boilers. The steam is conducted into two hori- 

 zontal cylinders, firmly secured, of the size already mentioned. The 

 shackle bars are connected with an axis on the extremity of which 

 is a crown wheel, working in another at right angles, on a shaft pla- 

 ced vertically. This vertical shaft carries at its upper end, which is 

 near the surface of the road, and directly in its center, a larger wheel 

 around the circumference of which the hauling ropes pass, and run on 

 rollers placed at regular distances down the plane. The plane over- 

 comes a height of one hundred and fifteen feet, with an inclination 

 like that near the Hudson, and running down a heavy embankment, 

 strikes the canal about half a mile from the principal street in Sche- 

 nectady, but the track is prolonged upon a level to within sixty rods of 

 the same.
