One beautiful evening in London, Alex stood on a busy railway station, waiting for the guests as he have reached before the train arrival also watching the trains arrive and depart with astonishing precision. how each train seemed to pass at a rapid pace, without collisions or delays. Filled with curiosity, Alex asked in surprise:

"How do these huge vehicles move so smoothly and quickly on the same track without collisions?"

This seemingly simple question, but it is illuminating many important questions related to a modern and interesting branch of engineering, signal engineering.

Question: What is signal engineering?

Answer: Signal engineering is a branch of engineering whose main purpose is to play an important role in the development, design and maintenance of signal systems that mainly play an important role in the movement of large vehicles and locomotives of certain types, such as trains and metros, etc.

Question: What are the duties of a signal engineer?

Answer: Thus, the duties of a signal engineer include the preparation and repair of signal systems, in addition to the following are some of the important ones:

• Planning and installation

• Maintaining communication between vehicles and control centers during movement

• Integrating control systems

• Continuous safety monitoring

Question: What is the importance of signal engineering?

Answer: Today, while the use of modern technology has created many conveniences in human life, it has also increased the risks, due to which many accidents are in the headlines of newspapers every day. Signal engineering plays an important role in preventing accidents, which mainly involves the transportation of trains and the prevention of accidents.

Question: In which departments does this branch of engineering play an important role?

Answer: Signal engineering plays a role in the following departments related to transportation:

• Subway and metros
  
  
• Railway companies
  
  
• Transport construction
  
  
• Control and automation companies

Question: Does signal engineering belong to any basic branch of engineering?

Answer: Yes, of course, since signal systems generally consist of sensors, circuits and various electrical devices, this branch of engineering is mainly associated with the field of electrical and electronics engineering in addition to railways -

Question: Which countries provide the most jobs in this field?

Answer: So, every country in the world that provides jobs equipped with railway technology, some of the important ones are as follows:

• China
  
  
• Japan
  
  
• Germany
  
  
• United Kingdom
  
  
• United States
  
  
• France
  
  
• Middle East

Question: Which universities around the world offer admissions related to signal engineering?

Answer: Due to its affiliation with a specific field, few universities in the world offer admissions in the relevant field, which are as follows _

• UK - University of Birmingham
  
  
• Germany - Technical University of Berlin
  
  
• China - Beijing Jiaotong University
  
  
• Australia - University of Sydney

At the end of our writing, we must say that the credit for the safe transportation of high-speed trains and underground metros in different cities, villages and developing countries goes to none other than this specific and little-known field of engineering.

Do let us know your valuable opinion regarding this specific and little-known field of engineering, thank you.
