History
Bua Yai Junction station was opened for service as Bua Yai Station on 1 May 1931 (then called Khorat Station). Initially, it was served by mixed train from Nakhon Ratchasima. The express stopped at this station for 10 minute watering and refueling pause after the introduction of Khon Kaen Express on 3 November 1939. Bua Yai Station became Bua Yai Junction on 19 August 1967, in conjunction with the opening of Kaeng Khoi–Bua Yai bypass route (Lam Narai Branch Line). This station was a drop-off point for Chaiyaphum Province (50 km from Bua Yai station) until the opening of Kaeng Khoi - Bua Yai route which changed the drop-off point for Chaiyaphum Province to Chatturat Station (40 km from Chatturat station). There are still intercity bus services from Bua Yai to Chaiyaphum as the bus terminal is just 500 meters from Bua Yai Junction. However, the traffic between Bua Yai to Nakhon Ratchasima main depends upon railway services due to the fact that there is no bus service between Bua Yai and Nakhon Ratchasima. Today, this station is Class 1 station as it is a refueling stop for many trains that travel the Kaeng Khoi - Bua Yai Bypass route as well as the trains from and to Nakhon Ratchasima.
