Hazardous goods by rail transport refer to substances and items with dangerous characteristics such as explosive, flammable, toxic, infectious, corrosive, and radioactive, which, during transportation, can easily cause personal injury, property damage, or environmental pollution, and thus require special protection. Large-scale transportation of such goods often requires dedicated freight lines, such as the Huida Railway, which serves the Zhonghai Petrochemical Industrial Zone.

Direct Lines: Logistics Direct Lines, Freight Direct Lines - commonly used in domestic logistics, referring to logistics companies transporting goods to their designated direct lines using their own trucks. Generally, they have their own branches at the destination. This ensures the trucks are loaded both ways. The purpose of running a direct line is to save costs, but it must be based on sufficient cargo volume; otherwise, it may result in losses. Therefore, direct line companies typically do not have a fixed schedule, as they operate when the truck is full, which also reduces the customer's transportation costs.
The benefits of a dedicated logistics line are lower transportation costs, but the drawback is that the delivery time cannot be guaranteed, making it unsuitable for time-sensitive goods.

Direct line logistics, also known as freight专线, refers to logistics companies using their own trucks, dedicated vehicles, or resources to transport goods to their designated专线 destinations. Generally, they have their own branches or cooperative networks at the destinations for continuous loading and unloading of goods.

Direct logistics, also known as freight专线, refers to logistics companies using their own trucks, dedicated vehicles, or resources to transport goods to their designated专线 destinations. Generally, they have their own branches or cooperative outlets at the destinations to ensure there is cargo for the trucks to carry both ways. The purpose of the专线 is to save costs, but it must be based on sufficient cargo volume; otherwise, it may result in losses. Therefore,专线 companies often have uncertain delivery times, shipping when the cargo is full, which also reduces the customers' transportation costs. The main advantage of direct logistics is the lower transportation costs, but the drawback is the uncertainty of land transport vehicle schedules, which may not meet the urgent cargo needs through transportation or business.
