Note, this is a subsection of Edward Bury and Co.
It was a six-coupled engine with outside cylinders, which, after trials on the Liverpool and Manchester Railway, was finally scrapped in December of that year, entailing a dead loss to its builder of about £1500 between the cost of building and the price of the scrap. 
..."No authentic illustrations or dimensions of this engine are known to exist, but from the description it would appear to have been modelled to some extent upon the practice of Stephenson and Hackworth, in that a return-flue boiler was used, but the outside inclined cylinders were connected to an independent driving shaft, to the cranks of which the coupling rods were also attached.
The Dreadnought was a complete failure. It was stated to have been tried by the contractor on the Liverpool and Manchester Railway in 1830, but was too heavy for the rails, and also proved very unsteady in service. It is probable that defective permanent way and light rails had something to do with the trouble. It was also stated that the outside crank pins of the driving shaft frequently broke. Mr Bury is supposed to have subsequently modified the engine by lowering the cylinders and readjusting the weight distribution, but further trials on the Liverpool and Manchester Railway again resulted in failure. The Dreadnought was then taken back to Bury's works and scrapped." From Short Histories of Famous Firms - Edward Bury and Co by Ernest Leopold Ahrons, The Engineer 1923/02/02.
The Dreadnought was afterwards bought by Mr. Hargreaves of Bolton, and continued to be used in the coal traffic for twenty years.
