There is no rail line to Phuket. Trains run to nearby Surat Thani. Songthaews are a common mode of transport on Phuket. Phuket's songthaews are larger than those found in other areas of Thailand. Songthaews are the cheapest mode of transportation from town to town. They travel between the town and beaches. There are also conventional bus services and motorbike taxis. The latter are found in large numbers in the main town and at Patong Beach. Traditional tuk-tuks have been replaced by small vans, mostly red, with some being yellow or green. Car taxis are quite expensive and charge flat rates between towns.
