New high-speed rail project in Thailand

The Chinese and Thai governments have reached agreement over the first phase of a high-speed rail link in Thailand. The long-running discussions regarding the 873 km network have largely been stalled by disagreements over costs.
This week, however, following three days of talks with Chinese officials, Thailand’s transport minister, Arkhom Termpittayapaisith said both sides had agreed a price of 179 billion baht (US$ 5.1 billion) for the first phase.



The line will run 271 km, from Bangkok to Nakhon Ratchasima, and will be followed by two more phases: a 355 km section, from Nakhon Ratchasima to Nong Khai province, bordering Laos; and a 246.5 km section, from Saraburi province to Rayong province.
As part of the latest agreement, Thailand will pay for all rail construction, while China is set to fund the line’s technical systems. The agreement marks another important step in China’s One Belt, One Road strategy, which aims to integrate the region into a cohesive economic area.

Types of rail fastening systems for high speed rail project

Fast Clip Fastening System

The fast clip fastening system has substantial global references on both concrete and steel applications. Fast clip fastening is a threadless fastening, with low maintenance and pre-assembly of the fastening which remains captive on the rail sleepers.
Fast clip fastening has been designed as a total system, in which all components are delivered to site pre-assembled on rail sleepers. Once the sleepers are laid, and the rail installed, the rail clip is simply pushed onto the rail by means of a simple drive action.
The features of fast clip fastening system:

• Rapid installation capability (up to 70 sleepers per minute)
• Pre-assembly and captive on rail sleeper
• Threadless, self tensioned fastening system
• Suitable for all track categories

Nabla Evolution Fastening System

Original Nabla Fastening Systems have provided safe and reliable tracks in Tram, LRT, Metro, Main Line and High Speed tracks. The special shape of the Nabla blade generates a dynamically stable toe load on steel rails when the rail nut is torqued.
The Nabla Evolution fastening system gives greater performance in tight radius curves, maintains consistent rail gauge, increased electrical insulation and improves the overall life expectancy of the assembly components.

• Tightening to refusal providing a constant force on the rail foot
• Lateral adjustment in 1.25mm increment
• Maintains efficient track gauge control and limits rail movement
