Human-machine interface of onboard equipment for urban rail transit signaling system Display Specifications

1 Scope

GB/T 46689-2025 is the Chinese national standard covering what the driver sees on the cab display - the speed and the braking curve, the movement authority and the mode, the alarms and their priority, and the layout and colours, so that a driver moving between lines reads the same picture the same way. First edition, under the Ministry of Transport. In force from 1 February 2026. Issued on 31 October 2025, it has been in force since 1 February 2026.

This document specifies the general requirements, display elements, interface division, and content of the human-machine interface (HMI) of onboard equipment in urban rail transit signaling systems. The content displays and describes the verification method. This document applies to the display and application of human-machine interfaces (HMIs) for onboard equipment in urban rail transit signaling systems based on communication-based train operation control. maintain.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Recommended speed The permissible speed is calculated comprehensively by the signaling system under the automatic protection function of the train.

3.2 wet rail mode In cases where the track surface becomes slippery due to rain, snow, ice, or other reasons, adjust the train's speed, traction, braking force, and tracking distance. These are operational control modes that reduce the risk of train slippage.

4.Abbreviations The following abbreviations apply to this document. CAM. Creep Automatic Mode RGB. Primary Color Light Model (RGB Color Model)
