Passengers on a Skytrain, Bangkok's excellent light rail, wait for the doors to close and the train to leave Siam station.
Bangkok has a great light rail system that runs for about 30 miles along two lines - the Silom line, which runs through the Central Business District and the Sukhumvit line which runs down Sukhumvit out to Mo Chit. The two lines meet and passengers transfer at the Siam station, conveniently in the heart of Bangkok's upscale shopping district.
The most expensive ticket is 40 Baht, about $1.30 US. The least expensive is 15 Baht. The trains are clean, cheap, air conditioned and faster than a car on surface streets. The perfect way to get around Bangkok.
I really enjoy riding the light rail, it's the best way to get from Point A to Point B and the people watching is great fun. Folks in the US think we Americans are addicted to our gadgets. But you haven't seen gadget addiction until you visit Thailand. Thai teenagers are constantly on their smart phones (and like the US, the iPhone is the smart phone of choice) texting, emailing, hitting web sites and playing Angry Birds.
I have more photos of the Skytrain in my archive or available from ZUMA Press.
