1835.

1835 Famous locomotive, built by R. and W. Hawthorn, which ran at the opening of the Newcastle and Carlisle Railway in 1835.

The use of four fixed excentrics was adopted by R. and W. Hawthorn, independently of Forrester's design, in the 0- 4-0 engine Comet, which started work in March 1835 on the Newcastle and Carlisle Railway. This engine had inside cylinders and inside plate frames, with axle guards bolted on. The cylinders, 12in by 16in, were inclined slightly upwards, and the piston-rods passed underneath the leading axle. The wheels had a diameter of 4ft . The Comet was an engine of what may be termed orthodox design, and. was the forerunner of a considerable number of similar engines. [1]
