Hot Correcting Machine for Rail Head Repair in Solid-bed Track

Abstract

When the rail head repair method is used to fix damaged rails, hot correcting work is required to prevent the repaired parts from dipping due to thermal contraction. The conventional straightening machine is applicable only to ballast tracks because the machine has a structure which lifts the bottom of the rail. Therefore, in this study, we developed new straightening machine that can also be applied to solid-bed tracks. Furthermore, we demonstrated the practicality of our proposed method using a field test.
