The invention relates to an integrated movable contact group for a railway. The integrated movable contact group comprises a movable contact ring and a movable contact seat arranged below the movablecontact ring, an integrated movable point steel column is arranged in the movable contact ring and comprises a smooth cylindrical surface and a threaded step, the top end of the integrated movable point steel column is arranged outside, the middle smooth cylindrical surface is sleeved with the movable contact ring, and the upper end of the lower threaded step is sleeved with a supporting isolationplate to block an insulating material; the lower portion of the supporting isolation plate is fastened through a first fastener, and after a certain distance is reserved, the lower end of the integrated moving point steel column is fixed through a second fastener to form an integrated moving point steel column assembly. Three groups of integrated moving point steel column assemblies are arrangedon the moving contact seat to form an integrated moving contact group together; and an insulating material is filled between the first fastener and the second fastener. The integrated movable contactgroup has the advantages that: the major defect of fracture failure of the conventional equipment is overcome, the requirements of no maintenance and zero failure are met, and the service life of theproduct is prolonged to the maximum extent.
