Preventing train derailments is a crucial aspect of ensuring railway safety. Here are some measures that can be taken to prevent train derailments: 1. Proper maintenance: Regular inspection and maintenance of rail tracks, switches, and crossing points can help identify any faulty or worn-out components that could potentially cause a derailment. These should be promptly repaired or replaced to maintain track integrity. 2. Inspect and maintain rolling stock: Trains must undergo regular inspections to ensure that the wheels, axles, couplers, and other components are in good working condition. Faulty or damaged parts should be identified and replaced promptly.
