494 ROBERT STEPHENSON'S NARRATIVE. APPENDIX. 



this mixed power endure to this day in the north of England. 

 The railway from the Hetton Colliery to Sunderland was 

 perhaps the earliest and most remarkable work in which these 

 two powers were most successfully combined. The Stockton 

 and Darlington Kailway is another instance where they were 

 combined with most success and efficiency, and although sub- 

 sequently the application of stationary power on that line was 

 partially superseded by tunnelling and locomotive power, the 

 change has only been justified by the traffic having become so 

 enormous, that a uniform and uninterrupted system was alone 

 applicable the stationary engine system being one that is 

 limited by the necessity of reciprocating the trains over a short 

 piece of railway at limited intervals. 



" In 1820 my father established in conjunction with two friends 

 of capital a manufactory of locomotive engines at Newcastle- 

 upon-Tyne. Before the opening of that establishment all the 

 locomotive engines which he had constructed had been made by 

 ordinary mechanics, working amongst the collieries in the north 

 of England. But my father felt that the accuracy and style of 

 their workmanship admitted of great improvement, and that 

 upon improvement of workmanship the perfect action of the 

 engine was greatly dependent. One great object that he had 

 in view in establishing this factory, was to concentrate a number 

 of good workmen for the purpose of realising and carrying out 

 the improvements in detail which he was constantly making. 

 This was the only manufactory at which locomotive engines 

 were made until after the opening of the Liverpool and 

 Manchester Kailway in 1831. After that great event other 

 mechanics began to devote their attention as a matter of regular 

 business to the construction of locomotive engines for railway 

 purposes. At the Newcastle factory all the engines that were 

 employed upon the Stockton and Darlington Railway were 

 made ; and for some time after the Liverpool and Manchester 

 Railway was opened this establishment alone supplied the 

 engines for working the traffic between those two important 

 commercial towns. 



" The writer of an article on Eailways which appeared in the 

 * Edinburgh Review ' in 1832, founded a charge of monopoly in 

 favour of the Newcastle factory, against the Liverpool and 

 Manchester Railway Directors, upon the fact that all the engines 

 on the Liverpool and Manchester Railway were made after my 

 father's plans, and in his factory ; the simple truth being that
