The Biotren (Spanish: Biotrén) is an at-grade urban commuter rail system that serves a large part of the city of Concepción, Chile, capital of the region of Bío-Bío, also known as Greater Concepción or Concepción Metropolitan Area, both synonyms of "city" according to the urbanistic standards and laws of Chile, of which this city is the second biggest, most populous and important of the country. Biotren connects the boroughs or comunas of Concepción Centro (downtown borough), Talcahuano, Hualpén, San Pedro de la Paz, Chiguayante and Hualqui. The system is managed by Ferrocarriles Suburbanos de Concepción S.A. (Fesub), which name comes from the former metrorail system of the city and is a subsidiary of Empresa de los Ferrocarriles del Estado (EFE), Chilean State Railways. Biotren is part of the Plan and Authority of Integrated Transit of Concepción, Biovías.

A unit of train UT 440 Modelo Concepción, on Chilean station of Hualqui, Región del Biobío.

The system was partially inaugurated on 24 November 2005 in a ceremony that counted with the presence of the then President of Chile, Ricardo Lagos.


It began to fully operate in 2006 because during the year 2005 the railroad lines were being upgraded for the new system. The AEL and AES trains that the former system used were replaced by UT-440 MC(Modelo Concepcion) units that were specially upgraded for the city of Valencia, Spain by Renfe.


Biotren stations or Bio Stations have a totally renewed architecture compared to the former system. The platforms have roofs and access for the handicapped. The fare is paid at the entrance and exit of the stations using a prepayment card called Biovías, with a deferred payment system according to the distance travelled. The card's recharge can be made in any station.

Rolling stockEdit

The Empresa de Los Ferrocarriles del Estado (EFE) invested a total of US $16.800.000 for the trains used in the system. The current fleet is composed of eight trains UT-440 Modelo Concepción of three wagons each, bought from the Red Nacional de Ferrocarriles Españoles (Spain State Railways, RENFE). The trains are painted orange and have 321 seats (20 folding seats) and a capacity of 590 passengers.
