The Chengkang Commandery Water and Land Transfer Hub consisted of three docks: a light-vessel dock, a heavy-vessel dock, and a railway dock.
The railway dock followed the rising-and-falling floating-dock design previously used in Weishan Commandery and Dongxin Commandery. The tracks extended all the way to the shore, allowing trains to be driven directly onto ships. There were also railway tracks running parallel to the dock, which were used to hoist cargo from trains onto ships.
The heavy dock also had shore-side bulk-cargo loading and unloading berths, specially designed for bulk goods such as ore. Its berths could only accommodate low-freeboard, hold-type Sand Transport Ships. On shore, vehicles or machinery could simply tip the cargo lightly into the ships at the water's edge, allowing bulk goods to be loaded with ease and greatly improving efficiency.
This was a method the Han Tribe had developed from its past experience using docks and from its recent inventions. In other words, once docks like this were built, they could still be used after Engineering Machinery such as loaders became available.
In addition, the dock and Train Station shared a huge Storage Area. The Storage Area contained not only warehouses but also open-air yards for piling up ores that were not afraid of wind and rain, such as coal.
With a dock, a Train Station was of course indispensable as well. Drawing on past experience, the Train Station built this time still had a huge waiting hall, complete with ticket windows and a Railway Management System.
However, the institution and the building had now been combined with the dock. The Train Station's waiting hall could be used not only to wait for trains but also to wait for ships. The ticket window sold not only train tickets but also ship tickets, while the management institution
