Rail transportation is an important part of the production process of modern urban transportation, which requires fine inspection and quality control, and industrial endoscopes are precisely the kind of equipment that can provide high-precision inspection and quality control. Electronic video endoscopes are high-tech inspection equipment that can be used in a variety of different industrial fields, including rail transportation. The following is an introduction to the application of electronic video endoscopes in the field of rail transportation:

　　1. Track detection: industrial endoscopes can observe the inside of the track through high-definition images and flexible probes, which helps to find track quality problems and avoid potential safety hazards.

　　2. Vehicle detection: industrial endoscopy can be applied to the detection and evaluation of rail transportation vehicles, which plays an important role in discovering and eliminating vehicle problems, such as wear and tear, corrosion and loosening.

　　3. Signal detection: industrial endoscope can be used for all-round detection and control of rail transportation signal equipment to ensure the quality and stability of signal equipment, detect problems and make adjustments in time, which helps to improve the safety and reliability of rail transportation.

　　The application of electronic video endoscope in the field of rail transportation is very important and effective, which can improve the quality and stability of rail transportation production, avoid the occurrence of undesirable situations, and at the same time improve the work efficiency and accuracy. With the continuous progress of technology and application expansion, the application prospect of electronic video endoscopy in the field of rail transportation will be more and more broad.
