State Railway of Thailand operates some diesel multiple units which are export versions of BREL’s British Rail Class 158s.
Obvious differences from their British cousins include metre gauge bogies, the primitive connections between cars, and a squat toilet. Underneath the advertising vinyls, the livery is remarkably similar to the colour scheme which the British DMUs once carried!
Although I didn’t get a ride on one, I had a quick look inside a set which was stood at Bangkok Hualamphong station waiting to form the 16:20 Bangkok – Chachoengsao service on 30 October 2005.
