Railway gauge rods are widely used on railway switch section. Railway gauge rod is used to link two steel rails together with one rod, which is used to improve the lateral stability of the rail and improve the track's ability to maintain rail track distance.
Turnouts exhibit characteristics including structural complexity, shortened service life, reduced operational safety, and intensive maintenance requirements, constituting one of the three critical vulnerable points in track infrastructure. Frequent maintenance and replacement activities severely disrupt normal heavy-haul railway operations.
GNEE RAIL supplies insulated gauge rods and non-insulated gauge rods in multiple specifications including 20×870, 22×880, 22×1050, 24×1050, 24×1250, 28×1810, and 28×1850. These track stabilization devices are compatible with 56-½" gauge tracks, rails weighing 60-140 lbs, AREMA 1-¼" standards, and rail sections of 43kg/m, 50kg/m, 60kg/m, and 75kg/m. Customized products are available according to client requirements.
The specialized technical team at GNEE RAIL established a refined vehicle-turnout dynamic analysis model based on the rigid-flexible coupling methodology. Validation of the model's reliability was conducted against field measurement results. This dynamic analysis model was then employed to investigate the influence patterns of negotiation methods and operating speeds on the dynamic characteristics of vehicle-switch interactions. Additionally, the effectiveness of three types of reinforcement measures implementable in the field was evaluated, leading to the following conclusions:
Installing 20 sets of gauge tie bars on the diverging route reduces maximum wheel-rail lateral forces and vertical forces by 43.0% and 5.1% respectively. All metrics decrease progressively with additional rail braces. Comprehensive evaluation recommends installing 10-14 sets of gauge retaining devices along the turnout diverging line.
