Downhill from Doï khuntan to Chiang Maï by train. After reaching the top of the line (577 meters above see level), the second engine is uncoupled and goes back to the botom of the moutain to help the next train... The train is expected by all the stray dogs in the neighborhood ... they know the dining car, and enjoy the remains of the meal! This is repeated three times a day, every day ... Let’s go to Chiang Maï...with Express 51! For a better quality video of trains of northern Thailand ;
