Which role is specifically held by the RTC in a train operation?

The role of the RTC, or Railroad Traffic Controller, is specifically to manually control train movements during train operations. This responsibility includes monitoring the location and speed of trains on the network, ensuring they safely progress on their designated routes, and managing switches and signals to prevent accidents or delays. The RTC plays a crucial role in maintaining the overall safety and efficiency of the rail system by making real-time decisions regarding train movements based on current conditions, including potential emergencies.

In contrast, overseeing passenger services, conducting mechanical inspections, and managing ticket sales fall outside the scope of the RTC's responsibilities. Passenger services focus on the experience and accommodations for riders, mechanical inspections are related to the maintenance and functionality of rolling stock, and managing ticket sales pertains to revenue generation and customer service aspects of rail operations. These tasks are usually handled by different departments or personnel within the railroad organization, emphasizing the specialized nature of the RTC's role.
