Instead of laying railroad rails across bridges across the river, the water railroad is loaded on a special giant ferry that crosses the rivers and lakes and transports the entire train to the opposite bank. Therefore, the water railway is like a floating bridge, which plays a role in connecting and communicating the railway lines on both sides.
The modern water-rail railway has extended from the river to the sea, and has developed from a short distance between the river banks to a long-distance ferry across the river. It concentrates on the advantages of railway, water transport, containerization and uninterrupted transportation, so that train vehicles can be directly boarded, which can avoid the goods being dumped on the dock, reduce the loss of goods, accelerate the efficiency of cargo transportation, and improve the port throughput. . More importantly, the water railway not only reduces the pressure on the ground rail transportation, but also greatly shortens the long-distance round-trip transportation of the train. At present, many countries with long coastlines and wide waters, such as the United States, Canada, Denmark, and Sweden, are vigorously developing the water railway.
Compared with the construction of the subway line, the water railway does not have to lay long-distance roadbeds and tracks, so the project volume is small, the investment is saved, the construction period is short, and the effect is quick. There are many coastal cities in China, with a coastline of more than 18,000 kilometers, and the development of water railways is very useful. From the sea to Ningbo, the water will cross the Hangzhou Bay by water, and the transportation distance can be shortened by 1/3; the sea railway from Dalian to Yantai can shorten the distance by more than 1,800 kilometers. Therefore, the development of water rail transportation is very suitable for China’s national conditions, and it is also a way to ease the current tension in railway transportation.
