According to AEROLAOS, EMU Class 1 & 2 use CR200J High Speed Train with speed of 160km/h Regular Train uses HXD3C locomotive with speed of 120km/h. HXD3C is electrical locomotive that pulls train passenger cars. It's definitely not going to be as comfortable or convenience as the Lanxang EMU.
@@Strawberry-vq7zl I think Laos China Railway company (LCR) creates 3rd class passenger train so price point is similar to bus ticket. Taking the train is more preferable because bus ride in northern Laos is slow and quite dangerous during raining season.
