Measurement for railway operations.

Ningbo Antong High-Speed Rail Technology Co., Ltd.

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.

01 / EARLY DEVELOPMENT

A Class 0 electronic precision track gauge

Our technical roots date to 2002. Development of the Class 0 electronic precision track gauge preceded the Beijing–Tianjin high-speed line, reflecting an early commitment to precision railway measurement.

02 / GROWING WITH HIGH-SPEED RAIL

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.

03 / MUSEUM COLLECTION

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.
