Description of Locomotive Model. 



The locomotive was designed by T. K. Crampton for high speed. 



Previous to this engine being designed no express trains were run on the 

 Continent. For this purpose it was selected in 1849 to commence an express 

 service between Calais and Paris, since which period to the present time, 

 1876, the Northern of France express trains have been worke.d almost exclu- 

 sively with this system of engine.
