Development of Locomotive 19 



and built an engine which it was hoped 

 would equal, if not surpass, the speed at 

 which Gooch's fliers travelled. The new 

 engine was called the * Cornwall ", and 

 it was given larger driving wheels than 

 any engine then running on the Great 

 Western. These were 8| feet in diameter, 

 but whilst the broad-gauge champions 

 built their engines in the usual way, 

 Trevithick was so afraid of his new machine 

 being top-heavy that he slung his boiler 

 below the axles of the driving wheels! A 

 speed of 117 miles an hour was claimed 

 for this freak of an engine, but, as the 

 careful timing of to-day was not then 

 thought of, the claim may be dismissed. 

 The * Cornwall " was afterwards tried 

 repeatedly by an expert to reach this 

 speed, but the best records secured was 

 far below the claim made. 



The chief interest for us in the " Corn- 

 wall ' is that she may be seen to-day 

 at work. Think of it this old locomotive 

 of over 80 is still in harness, though the 

 London, Midland and Scottish, like kindly
