To ensure the safety clearance of freight trains, the Railways can take the following measures:

• Perform regular maintenance checks on the freight train as well as the tracks to ensure that they are in good condition and free from any defects.
• Install automatic braking sensors on the tracks and in the freight trains to activate emergency brakes in case of malfunctions or emergencies.
• Limit the speed of freight trains to ensure that they are within safe limits.
• Implement advanced signal systems to warn train drivers of any upcoming obstructions or anomalies on the tracks, such as damaged rails.
• Enforce strict adherence to safety guidelines and regulations, including proper training of freight train operators and crew members.
• Monitor the operation of freight trains with the help of advanced technology such as sensors, GPS, and cameras to have real-time information about the train's location and operations.

These measures can ensure that freight trains are operated with adequate safety clearance, which can reduce the probability of accidents, thereby, keeping freight trains and freight personnel safe.
