What type of communication system is used by operators for coordination?

Operators typically use two-way radio systems for coordination because they provide real-time communication that is essential for the dynamic environment of light rail operations. This form of communication allows for immediate and clear exchanges of information, which is critical in ensuring safety, responding to emergencies, and managing operations efficiently. The two-way radio system enables operators to communicate with dispatchers and other team members while on the move, helping to coordinate schedules, report issues, and receive updates without delay.

While smartphone apps could facilitate communication, they may not always provide the immediacy and reliability needed in critical situations. Email communication lacks the immediacy required for real-time operational coordination, as it can involve delays. Hand signals, although useful for direct interaction in specific situations, do not offer the comprehensive communication capabilities required for broader operational coordination. Hence, the two-way radio system stands out as the most effective solution for operators in this context.
