What is the purpose of a ticket sweep?

The purpose of a ticket sweep is to verify that all tickets have been lifted by customers. This process involves checking that each passenger on the train has a valid ticket and has properly registered for their journey. Conducting a ticket sweep ensures compliance with fare collection policies and helps maintain the integrity of the ticketing system. It is an important part of operational efficiency and financial accountability within the railway service.

The other options do not accurately reflect the primary goal of this procedure. Collecting additional fare from customers, checking for lost items, or inspecting passenger seat conditions are different functions that are not the main focus of a ticket sweep.
