Work began February 2014 and is scheduled to last two years.
Somjit Khokram, head of the railroad sleeper alteration operation from Thaipicon Co., Ltd., said Thaipicon has organized workers into teams of 15-17 people.
Workers install new concrete railroad ties near the Pattaya train station.
Each tie, or sleeper, weighs 36kg. They are spaced 60cm from each other. Each worker earns about 80 baht per tie. In a day, one family can install as many as 40 ties, he said.
The concrete ties will enable the State Railway of Thailand to use faster trains, with locomotive speeds increasing from 90 kilometers per hour to 120 kph. They also can prevent derailments and carry heavier trains stacked with more cargo.
The State Railroad has proceeded with improving the railroad system by changing rails to a bigger size and using concrete ties to be able to accommodate the amount of trains, axle load and increase train speed.
