摘要： A track maintenance vehicle having a workhead (22) that is pivotally mounted to the superstructure at its upper end. The workhead includes a blowing tube (82) mounted at its lower end and a vertical cylinder (56) that is selectively extendable and retractable to control the height of the blowing tube. The vehicle includes a control system that controls the height of the blowing tube as well as the left/right and fore/aft positions of the workhead. The track maintenance vehicle further includes an automated height control system that automatically extends and retracts the vertical cylinder (56) to position the blowing tube at a uniform height despite its lateral disposition.
