Mobile waterjet rail repair system

A method of operating an ultra-high pressure liquid jet system having a pressurized fluid that is at least 20,000 PSI during a rail cutting operation or a re-profiling operation, the method comprising:

• positioning, on two rails spaced at a distance from each other, a translatable frame having (i) a set of wheels for contacting the two rails, and (ii) two sets of three liquid jet processing heads fluidly connected to an ultra-high pressure liquid pump, each set of three liquid jet processing heads aimed at one of the two rails;
• providing an abrasive feed system coupled to the liquid jet processing head to provide an abrasive to the liquid jet;
• providing, to the two sets of three liquid jet processing heads, from the ultra-high pressure liquid pump, pressurized fluid forming two sets of three liquid jets that contact the two rails;
• and
• translating the frame relative to the rails, thereby performing a processing operation on a linear length of the rails along a direction of translation.

A method of operating an ultra-high pressure liquid jet system, the method comprising:

• positioning, relative to a rail, a translatable frame having a liquid jet processing head fluidly connected to an ultra-high pressure liquid pump;
• 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;
• providing an abrasive feed system coupled to the liquid jet processing head to provide an abrasive to the liquid jet;
• operating the ultra-high pressure liquid jet system according to a step of selectively mixing an abrasive to the liquid jet to at least 20,000 psi during a rail cutting operation or a re-profiling operation 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.
