Where is the current operating mode displayed in the CBTC-TOD?

The current operating mode in a Communication-Based Train Control - Train Operations Display (CBTC-TOD) is typically displayed in the upper-left corner of the screen. This is a common design practice in user interface layouts, as it allows for quick access and visibility of critical information that operators need to reference frequently. The upper-left area is often where users expect to find vital indicators or status information, due to traditional reading patterns and interface design standards. This positioning helps ensure that the operator can easily monitor the operating mode without having to divert their attention from other critical tasks or controls displayed on the screen.
