Removing wheels from car trucks is a tedious andexpensive operation in the majority of street railwayshops. Perhaps it would be a good plan to step overand see how our steam road brethren do it. It will soonbe found that here is another thing that street railwayscan learn from steam roads. The plan used in steam roadshops for removing wheels from trucks was put in usein the South Chicago City Railway shop several monthsago by R. D. Rowe, formerly superintendent, and , formerly electrician of that company. It involvesthe use of a hydraulic or pneumatic jack and a short sec-tion of removable rail at that point of the pit at which itis desired to take out the wheels. In operation the planis simply as follows: The car is run over the pit whichhas the sectioned track and the hydraulic jack is placedunder the axle to be removed. The jack then lifts the.

Blocks are put under thetruck frame, the sectioned rails are taken out and thejack is lowered enough to allow the axle to clear thetruck. The axle is then swung around a quarter of aturn so that it is parallel with the tracks, and beingbetween them can be lowered into the pit without furtherobstruction. The hydraulic jack is of course on a smalltruck of its own so that it can be run around the jack has an arm, the ends of which are shaped toreceive the car axle. The fire pressure which is kept atloo pounds over the building is used to work the hydrau-lic jacks. Compressed air is used for this in many rail-road shops. Compressed air has the advantage of neverfreezing or making disagreeable leaks and when com-pressed air has to be used for other purposes it is betterto have compressed air apparatus throughout, than tohave part pneumatic and part hydraulic.
