HOW THE ENGINEER HELPS THE RAILWAY 



SOME remarkably good locomotive tractors 

 have been designed and placed on the 

 market by M. Gaston Moyse, of Paris. 

 These machines have been tried at various 

 goods depots of the French Railways ; having 

 proved successful there, they have been 

 experimented with in various industrial 

 works. 



Many attempts at the adoption of internal 

 combustion type locomotives have been 

 made, and although a fair amount of suc- 

 cess has been achieved there have been 

 found inherent difficulties, such as lack of 

 elasticity or flexibility in the gear for the 

 transmission of the power generated by the 

 engine, in other words the difficulty has 

 been to secure an easy application of 

 power.
