Hyundai Rotem delivers 2nd generation KTX-Eum to Korail

South Korea's high-speed rail network is getting an upgrade.

Hyundai Rotem announced Monday that it has delivered the second-generation KTX Eum to Korail, more than four months ahead of schedule.

The new fleet will soon be put into service on the Gangneung Line.

With improved suspension, a reinforced frame, and advanced soundproofing, the trains promise a smoother, quieter ride.

They're also equipped with better air quality control inside, and they meet the highest safety standards even at top speed.

Hyundai Rotem says the second-generation Eum is also set to make a push overseas, targeting markets in the Middle East and Eastern Europe.

Last year, the company signed its first export deal for the model — a contract with Uzbekistan worth 270 billion won, or roughly 200 million U.S. dollars.
