Abstract
A hydraulically powered apparatus for removing railroad track retainer clips from retainer chairs. A support housing carries a pair of compression arms which, when hydraulically actuated, force a pair of retractor blocks together. The retractor blocks in turn carry clip compression flanges which compresses the clip so as to unlock it from the chair and clip engagement pins which withdraw the clip from the chair which the retractor block is pivoted rearward by a hydraulic actuator.
