Bangkok: Preparing for "simulated train operation" with the air-conditioned KIHA 40 and KIHA 48 diesel railcars from Japan, the State Railway of Thailand (SRT) conducted a test run on the Don Mueang - Phra Nakhon Si Ayutthaya route on April 19, 2026. The SRT utilized these diesel multiple units (DMUs) for this service, reflecting its commitment to improving service quality, providing more travel options for the public, reducing the use of private vehicles, alleviating traffic congestion, and promoting a more efficient rail public transportation system.

According to Thai News Agency, the KIHA 40 and KIHA 48 railcars are notable not just for their "newness," but for their design charm, which evokes a classic, warm, and unique feeling. The color scheme, shape, and interior atmosphere contribute to a journey that feels more like a story, setting them apart from the typical trains. Passengers can enjoy breathtaking natural scenery along the route, including rice fields, communities, and the way of life along the tracks, providing a simple yet surprisingly memorable experience.

This test route covers Bangkok (Hua Lamphong) Station - Don Mueang - Ayutthaya - Ban Phachi Junction - Chachoengsao Junction and back to Bangkok, linking major cities and surrounding areas. Notably, this is an air-conditioned third-class train, offering comfort at an affordable price of only 30-50 baht, making it ideal for working professionals, students, or travelers seeking a change of scenery. The first service is scheduled for April 20, 2026, and will be offered on a trial basis to evaluate and improve the service to best meet passenger needs.

Ultimately, the introduction of the KIHA 40 and KIHA 48 railcars may not just represent "new trains" but rather a new perspective on travel that is classic, simple, and full of charm, aligning with long-term sustainable development goals by reducing reliance on private vehicles and decreasing energy consumption.
