Freight Trunk Line, officially known as the Freight Train Trunk Line Railway, commonly referred to as the Freight Railway or Freight Line, is a railway system that operates solely with cargo trains and technical service trains. The types of freight trunk lines vary, generally categorized into two major types: national heavy-haul railways and local dedicated railways. The distinguishing feature of freight trunk lines is their differentiation from passenger trunk lines and mixed passenger-cargo lines.

Railway Introduction

Freight专线, also known as Freight Train专线 Railway, abbreviated as Freight Railway, refers to a railway system primarily operating cargo trains with necessary technical operation trains as support. There are two main types of Freight专线: national heavy-haul railways and local dedicated railways. Within the domestic logistics industry, the dedicated railways are also widely referred to as Logistics专线, where logistics companies transport goods to other dedicated destinations using their own trucks. The headquarters of the Logistics专线 companies usually have branches at the destinations, ensuring that trucks are loaded both ways, reducing the risk of empty return trips and associated costs.

Rail Type

Administrative

National trunk railways, inter-regional trunk railways, inter-city peripheral railways, and municipal dedicated lines.

Technology

National Class I Rail (including heavy-haul grades), Class II Rail, Class III Rail, and Class IV Rail.

Features

Dedicated rail lines, primarily including military railroads, coal transportation corridors, industrial and mining railroads, and forest railroads.

Railway Transportation

Hazardous Materials

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 Shell China Refining & Petrochemicals Industrial Park.

Special commodities

Special commodities transported by the dedicated railway system for freight include long and heavy goods, commercial vehicles, and containers.
