Define revenue vehicle and provide an example.

• A. A vehicle used exclusively for freight operations, not carrying passengers.
• B. An in-service vehicle used to transport passengers or goods for revenue; example: a passenger car in a metro train.
• C. A decommissioned vehicle stored for spare parts.
• D. A vehicle used for training new operators.

Answer: (B)

A revenue vehicle is an in-service vehicle that moves people or goods to generate revenue, meaning it is actively used to carry riders or freight for payment. The example of a passenger car in a metro train fits perfectly because it is operating in service and transporting passengers who pay fares, which is exactly revenue activity. The other descriptions describe vehicles not in revenue service or not intended to generate revenue (such as decommissioned assets or those used only for training), or they don’t clearly state both being in service and carrying passengers or goods for revenue.
