152 Book of Locomotives 



Fuel still remains one of the biggest of 

 our railway problems in Britain. The suc- 

 cess of the Great Western engines with 

 their enormous loads is largely due, apart 

 from their excellent design, to the use of 

 the very best Welsh steam coal. Dear 

 though it be, it is a real economy to use it 

 freely for express work, and, when possible, 

 for slower. 



Oil has never been popular, and most of 

 the engines fitted during the coal shortage, 

 following the Strike of 1926, have now 

 reverted to coal.
