In case an engineer does not obey a stop signal, what could potentially occur?

The consequence of not obeying a stop signal is the potential for an accident, which could occur due to a variety of factors such as colliding with another train, entering a zone populated by workers, or derailing. Stop signals are crucial safety measures that communicate vital information about the conditions on the tracks ahead. When an engineer disregards these signals, it significantly increases the risk of danger not only to the train and its passengers but also to other trains and personnel in the vicinity. Understanding the importance of adhering to stop signals is paramount in ensuring the safety and reliability of train operations.
