The Thaksin Express (Thai: รถด่วนพิเศษทักษิณ) is an express train run by the State Railway of Thailand (SRT) between Bangkok and Su-ngai Kolok, a border town in Narathiwat Province and the end of the southern rail line. Thaksin is a Thai word for 'south' (from the Sanskrit word dakshin), thus this train is referred to as the "Southern Express". The train's passenger cars include 1st- and 2nd-class air conditioned sleepers, 2nd-class fan sleepers, 2nd-class fan seating coaches, 3rd class air conditioned and fan seating coaches, and a dining car.
