Rail Fish Plate replacement process

Preliminary preparation
Safety inspection and assessment:
Thoroughly inspect existing rail cleats to determine if they show signs of wear, cracks, or other damage.
Assess the overall condition of the track and surrounding infrastructure, including the smoothness and stability of the track and the potential impact of the surrounding environment.
Develop a replacement plan:
Based on the inspection results, make a detailed replacement plan, including a list of required personnel, equipment and materials.
Determine the specific timetable and process of replacement to ensure that the normal operation of the railway will not be too much affected.
Identify and evaluate potential security risks, develop appropriate security measures and emergency plans.
Communication and coordination:
Communicate and coordinate with other relevant departments or teams to ensure that the replacement process is fully supported.
Inform railway users or passengers who may be affected, and make appropriate service adjustments and explanations.
Implement replacement
Site preparation:
Set up safety warning signs at the replacement site to ensure the safety of personnel and equipment.
Prepare necessary tools and equipment, such as wrenches, bolt cutters, and new splints.
Remove the old splint:
Remove the bolts and fasteners from the old splints step by step according to the safe operation procedures.
Carefully remove the old cleats from the tracks to avoid damage to the tracks.
Install new splint:
Clean rail and cleat installation locations to ensure they are free of impurities and dirt.
Place the new splint in the desired position, ensuring a tight fit to the rail.
Use professional tools and equipment to tighten bolts and fasteners according to specified torques and sequence.
Check and debug:
Conduct a thorough inspection of the newly installed splints to ensure that there are no loose, misaligned or other problems.
Carry out the necessary debugging work to ensure that the fit between the splint and the rail is good and meets the operation requirements.
