By running off a raised rail section and becoming airborne, the Rail Rescues could combine to form the Supertrain Megazord. As the Rail Rescues were large enough to house the Lightspeed Rescuezords, the Supertrain Megazord was substantially larger than the other Megazords. Rail Rescues 1 and 2 formed the arms, Rail Rescue 3 formed the thighs, head, and torso, and Rail Rescues 4 and 5 formed the legs. It had missiles and an Ion Turbine weapon at its disposal, known as its Gatling Blasters. At first almost twice as tall as its opponents, some later monsters were grown even larger to combat the Supertrain Megazord.
