Tanklike Tractor Carries Welder to Repair Job
Maneuverable as a war tank, an endless-tread tractor, just developed by Westinghouse engineers, carries a built-in welding outfit right to the point where it is needed for railway repairs. The fifteen-foot machine easily ambles across rails, runs along side slopes as steep as forty-five degrees without overturning, and climbs a ramp onto a flat car when its work of repairing battered rail ends and worn crossings is done. Its gasoline motor drives dynamos that supply current for the welding electrodes.
