OUR ORIGINS
Inventor of the digital railway track gauge
Antong carries forward an early railway electronic measurement heritage. R&D began alongside high-speed rail development in China, progressing from Class 0 electronic precision track gauges to field inspection equipment.
R&D alongside China's railway development
Starting with track gauge measurement, our work expanded to inspection, monitoring and calibration equipment in response to railway field requirements.
From mechanical to electronic gauges
Two historical models, DGJC-A and DGJC-B, are exhibited at the China Railway Museum, documenting the transition from mechanical to electronic railway measurement.
CHINA RAILWAY MUSEUM
From mechanical to electronic gauges: history on display
Antong is the inventor of the digital railway track gauge. Two historical models, DGJC-A and DGJC-B, feature in the China Railway Museum’s historical displays, documenting the transition in railway measurement. This continuing technical heritage supports railway operations today.
