Tren de Alta Velocidad Prasiano (usually shortened to TAV) is a high speed rail service in Prasia, operated by Ferrocarriles de Prasia, the national rail service. TAV services started in 1997, replacing other intercity services on the San Luis-Adahuesca route. Since then, a line connecting this route with San Ramon was opened in 2002, with a service linking San Serena with Guadajoz opening the following year.
