PLAN No. 1141. ELECTRIC RAILWAYS
Applications of the process by electric railways are similar to those by steam railways. There are, however, more opportunities for doing welding at the table. Of such a nature are restoring of armature bearing housings and frame heads, worn axle seats for motors and axle caps, journal boxes, pinion seats and keyways, brush holders, trolley bases, and third-rail shoe castings. Heavy broken parts such as truck frames, drawheads, brake hangers and body bolsters are repaired. To some extent the process is used also in bonding rails and in welding steel trolleys. Most of the work is handled in the shop, where, however, electric welding is coming into more general use, owing to the availability and economy of electric power.
