The CRH2A- 2460 EMU passes across the Xijiang River Bridge on the Nanguang Railway, and the CRH2A- 2460 EMU is the only new head CRH 2A EMU in China Railway.
The Xiaoxiang Bridge of Zhaoqing on the South-Guangzhou Railway is undoubtedly the most difficult section of the South-Guangzhou Line to construct. the layout of the bridge requires the Feiying Tunnel of 7143 meters in the west and the Beiling Mountain Tunnel of 12438 meters in the east to connect to Zhaoqing East Station after crossing Dinghushan. The main span of the bridge is 450m half-through steel box arch bridge, which allows the EMU to pass through at full speed (200km/h), which is difficult to construct.
