To provide a road/rail working vehicle capable of easily performing wiring operation with improved work efficiency even in a crossing where a traveling body is difficult to change its direction by a narrow obstacle present therein.
This road/rail working vehicle travelable on a road by the tire wheels (road traveling wheels) 11 and also travelable on a track by iron wheels 65 comprises: a rotation angle detector (rotation angle detection means) 91 for detecting the angle of deviation formed by the longitudinal center axis of a turntable 63 relative to the longitudinal axis of the traveling body; and a controller for controlling the operation of an iron wheel drive motor 73 to limit the maximum speed of the track traveling speed of the traveling body 10 to a predetermined speed or below when the angle of deviation detected by the rotation angle detector 91 comes out of the range where the longitudinal direction of the turntable 63 is aligned with the longitudinal direction of the traveling body 10.
