What do trains proceed on in Release mode?

In Release mode, trains rely on STDS signal aspects. This mode allows for enhanced operational flexibility by permitting the train to proceed based on the aspects displayed by the Synchronous Train Dispatching System (STDS). This system is designed to optimize the flow of trains and manage their movement more efficiently by using a set of defined signal aspects that indicate the status of track conditions ahead, allowing for appropriate responses from the train crew.

Using STDS signal aspects is critical because they provide real-time information about track occupancy, speed restrictions, and safety conditions. This operational mode emphasizes the importance of following the signals provided by the STDS, as they are established based on a combination of safety protocols and traffic management needs.

In contrast, proceeding on manual signals only, following standard operating procedures, or relying on visual indicators from the conductor do not reflect the automated and integrated approach that STDS offers in Release mode. Thus, the reliance on STDS signal aspects ensures that trains operate under a system designed for efficiency and safety in modern rail transportation.
