Siemens Desiro
Nine Siemens Desiro sets were purchased. City services are operated by five three-car trains, and the express services by four trainsets with a fourth car for check-in baggage. The first trains left Germany in September 2007, and testing in Bangkok began in March 2008. On 15 May 2012 the Thai Cabinet approved a budget of 5.2 billion baht for the SRT to order seven new, four car sets of Siemens Desiro rolling stock to be delivered by 2014. However, as of June 2013 no orders for new rolling stock had been placed.
