How Engineer Helps Railway 171 



consumption will be more than halved, and 

 the lubricating costs approximately one- 

 fourth. 



By adopting an automatic lubricating 

 system there is no time lost in standing 

 by for oiling up. The whole of the work- 

 ing parts are adequately protected from 

 track grit; the boiler is as indestructible 

 as it is possible for a boiler to be, and 

 it is pressed to produce a high-pressure dry 

 steam. Then it is possible to halve the size 

 of the boiler, and also to protect it thoroughly 

 against radiation. Steam is raised in about 

 half the time as compared with the usual 

 type of locomotive, and, taking the power 

 exerted, the weight is certainly less. From 

 a working point of view there is the gain 

 that one man can give adequate attention, 

 the fireman being dispensed with. 



In the Atkinson- Walker rail tractor the 

 engine is placed vertically, right under the 

 driver's eye ; it runs at a much greater speed 

 than the driving wheels, and the claim is 

 made that as a consequence it asserts great 

 starting effort. The steam is distributed on
