Product Description

30kg/m rail (P30 rail) is an I-beam and named after its weight per meter. Therefore, one meter of 30kg rail weighs 30.1 kilograms and widely used in railway, construction, mining and other industries. According to different metric units, 30kg rail can also be expressed as 60 lb/yd rail. Its standardized size and precise design ensure seamless integration with the existing railway network.

Gnee not only provides rails, but also provides rail fasteners such as bolts, nuts, fishplates, rail fastener systems, etc. In addition to 30kg/m rail tracks, we also provide other specifications of light rails, heavy rails and crane rails. Similarly, we provide customers with customized services such as size, surface treatment, testing, and matching fastener systems.

Application

30kg rails can be used in the following scenarios around the world

Application of 30kg/m rails

Urban rail transit system

Light rail/tram lines

P30 rails are often used in low-axle-weight lines such as urban light rail and trams due to their light weight and flexible laying.

Subway branch lines or non-core sections

Used in subway extension lines or suburban sections with low passenger flow

Special lines for industrial and mining enterprises

In-plant internal transportation tracks

Used for internal material transportation lines in mines, ports, and large factories, carrying small and medium-sized locomotives or mine cars.

Warehouse logistics tracks

Operating tracks for warehouse hoisting equipment (such as gantry cranes), suitable for low-frequency and light-load scenarios.

Station and marshalling yard lines

Railway station sidings and shunting lines

Applicable to low-speed operation sections such as train marshalling and parking

Locomotive depot maintenance lines

The tracks in the locomotive maintenance depot have low load-bearing requirements, and P30 can meet the daily maintenance and traffic needs.

Local railway branch lines

Regional railway branch lines

Temporary construction tracks

Temporary transport tracks at large infrastructure construction sites (such as bridge construction) that can be quickly dismantled and reused after completion.

FAQ

The 30kg/m rail is an economical light rail suitable for low-speed, light-load, and non-trunk scenarios.

Maximum axle weight and speed limit for 30kg/m rails

Allowable axle weight: ≤16 tons (recommended ≤14 tons)
Design maximum speed: ≤60km/h (usually ≤30km/h)
Minimum curve radius: ≥120 meters (small radius is prone to wear)

What are the technical points when replacing rails?

Key requirements include 3:

The height error between the new and old rails is ≤1mm, and the left and right teeth are ≤1mm;
The influence of thermal expansion and contraction needs to be calculated for the rail gap reservation;
The placement of the new rail: ≥300mm (track center) or ≥150mm (sleeper) from the line rail
