What is the primary function of a conductor during the boarding and alighting of passengers?

The primary function of a conductor during the boarding and alighting of passengers is to oversee safety and compliance during the process. This involves ensuring that all safety protocols are followed, such as encouraging passengers to use designated entry and exit points and assisting those who may need help, such as the elderly or those with disabilities. The conductor is responsible for creating a safe environment and monitoring the boarding and alighting to prevent accidents or incidents.

While collecting tickets and assisting passengers to their seats are important aspects of a conductor's responsibilities, the overarching priority during boarding and alighting is maintaining safety and ensuring that all procedures are compliant with regulations. This focus helps in managing the flow of passengers and reducing the potential for chaos during busy boarding periods. Selling refreshments is typically not a primary responsibility during this time and does not align with the key role of safety and compliance.
