Abstract
There is described a railroad track maintenance machine having a horizontal track undercutter and a vertical rotary trench digging wheel at one side of the track. The bucket wheel is constructed such that there is lateral access into the wheel from the inner side of the bucket wheel and the buckets themselves are open on their inner sides. The undercutter is located with its delivery end adjacent to and spaced inwardly of the trenching wheel near its bottom center so that ballast removed by the undercutter is projected into the buckets through their open sides.
