Which designation is used for trains other than passenger, work, or track car extras?

• A. Passenger Extra
• B. Work Extra
• C. Extra Train
• D. Track Car Extra

Answer: (C)

Extras are trains that run outside the normal timetable and are given a designation to show what their role is. Among these, certain terms are reserved for specific kinds of non-regular service: Passenger Extra for trains carrying passengers, Work Extra for maintenance-related movements, and Track Car Extra for track department equipment. When a train doesn’t fit those categories, the broad label used is Extra Train. This designation covers miscellaneous or non-standard services, such as freight or other special runs, because it isn’t a passenger service and isn’t a work or track-car movement.
