  "abstract": "A dual-use, battery-operated rail lifting device for railway maintenance is disclosed. The device includes a two-piece housing assembly and an internal lift mechanism actuated by a battery-powered electric drive unit coupled to a screw threaded rod. A lifting L-shaped structure extends vertically from ground level to raise and stabilize a running rail segment without manual lifting or hydraulic systems. The rail lifting device may be ergonomically configured for waist-level operation, reducing torsional stress and back injury risk, while increasing stability, load capacity, and durability. The design may be adaptable to various rail sizes, lightweight, and operable with either an integrated motor or a detachable off-the-shelf impact drill, thereby simplifying field operation in remote railway environments.",
