How are Revenue Trains defined?

Revenue trains are specifically defined as those that generate income by transporting passengers. This classification is crucial to understanding rail operations, as these trains directly contribute to the operational revenues of a rail company. They are utilized for carrying individuals from one destination to another, which is a core function of public and private transportation systems.

In contrast, other classifications such as trains that carry only cargo or those under maintenance do not fulfill the purpose of generating passenger-related income. Therefore, recognizing revenue trains as those that carry passengers is essential for grasping the economic model of train operations and the specific role these services play in the overall rail transport industry.
