Mobile waterjet rail repair system
A method of operating an ultra-high pressure liquid jet system includes positioning, relative to a rail, a translatable frame having a liquid jet processing head fluidly connected to an ultra-high pressure liquid pump. The method also includes providing, to the liquid jet processing head, via the ultra-high pressure liquid pump, a pressurized fluid forming a liquid jet that contacts the rail such that the pressurized fluid is at least 20,000 PSI during a rail cutting operation or a re-profiling operation. Steps of the method include providing an abrasive feed system coupled to the liquid jet processing head to provide an abrasive to the liquid jet and translating the liquid jet processing head relative to the rail, thereby performing a processing operation on a linear length of the rail along a direction of translation of the rail.
