To effectively use grinding surfaces of grinding belts that are wider than the width of rail heads and swiftly and accurately re-profile rail joints.SOLUTION: It includes a trolley body 11, a rail re-profiling part 12 provided on the trolley body 11, and a pressing plate elevating mechanism part 13 that is provided on the trolley body 11, raises and lowers a pressing plate 13b1 inside a re-profiling belt 12c across front and rear grinding belt rollers 12b,12b and re-profiles rail surfaces. In the front and rear parts of the trolley body 11 there is a wheel lateral slide mechanism part 14 which has plunger pins 14c which slide wheel support parts 11e,11e that rotatably support the wheels 11f,11f, respectively in the lateral direction of the intersecting rail with respect to the longitudinal direction of the rail and fixed at multiple positions, and lateral positioning plates, etc., which have the well-known LM guide comprising LM rails and LM blocks and multiple positioning holes.SELECTED DRAWING: Figure 1
【課題】レール頭部の幅よりも広い幅の研削ベルトの研削面を有効に活用でき、かつ、レール接合部を迅速かつ正確に削正する。【解決手段】台車本体１１と、台車本体１１に設けられたレール削正部１２と、台車本体１１に設けられ、前後の研削ベルト用ローラ１２ｂ，１２ｂ間に渡された研削ベルト１２ｃの内側の押当て板１３ｂ１を昇降させてレール表面を削正する押当て板昇降機構部１３とを備え、台車本体１１の前後には、それぞれ車輪１１ｆ，１１ｆを回転可能に支持する車輪支持部１１ｅ，１１ｅをレールの長手方向に対し交差するレールの横方向にスライドさせて所定の複数の位置で固定するプランジャピン１４ｃやＬＭレールおよびＬＭブロックからなる周知のＬＭガイドや複数の位置決め孔を有する横方向位置決め板等を有する車輪横方向スライド機構部１４を設ける。【選択図】図１
