 built in 1857 and 1882 but whilst the 

 better known engine is scarcely like the 

 original, the Hetton locomotive did not 

 lose much of her personality in the two 

 rebuildings. 



At the last rebuilding a new motion 

 the link was fitted. Some very interesting 

 points about the old engine may be men- 

 tioned here. The regulator is fitted beside 

 the dome; adjacent is the reversing lever 

 and handbrake. This unique arrangement 

 of the controls meant that the driver stood, 

 not on the footplate, but upon a running 

 board at the side of the boiler, and just 

 above the wheels. The principal dimen- 

 sions of the veteran are : Cylinders, 10^x24 

 inches; driving wheels, 3 feet in diameter; 

 boiler barrel 10 feet 2 inches long, with a 

 diameter of 4 feet 4 inches; grate area 7f 

 square feet, heating surface, 157^ square 

 feet; boiler pressure (much higher than the 

 original boiler, of course), 80 Ib. per square
