In Samut Songkram, there is a unique market that is held every day literally on the rail tracks. Just before the train arrives in the town, the market stallholders have to pull back their awnings and remove their produce from the tracks. They then have to repeat all of this when the train returns. Fortunately it is not a busy track. The train leaves four times and it arrives four times. The track is not part of the national network. It only runs between Samut Sakhon and Samut Songkram. You can do this easily as a day trip from Bangkok. I wrote a story about this a couple of years ago. I was back there again at the weekend to shoot a video of the train arriving at the station. Last time I was on the train. If you go to Bangkok Day Trips you can view my full story as well as view videos and photos of this location.
