The Unidad Ejecutora del Plan Ferroviario Provincial (UEPFP) (in English: "Executive Unit of the Provincial Railway Plan"), mostly known under its trade name Ferrobaires, was a public railway company which operated extensive long-distance passenger trains throughout the Buenos Aires Province in Argentina.

The company was primarily owned and funded by the Buenos Aires provincial government led by Eduardo Duhalde.

[6] All of the routes which were managed by Ferrobaires were previously operated by Ferrocarriles Argentinos, the country's former national passenger railway corporation.

Buenos Aires proposed to work with other municipal governments to create a company that operated the railway services.

[17] In June 2016, after a Ferrobaires train collided with a Belgrano Cargas y Logística freight train in Rawson, a city in Chacabuco Partido, the Government of Buenos Aires Province led by María Eugenia Vidal ordered the suspension of all services (eight in total) operated by Ferrobaires.

[5] In July 2016, it was announced that Ferrobaires would be shut down and all of its personnel and infrastructure transferred to the National Government,[19] a process that had been unsuccessfully attempted in 2007.

[20] Passenger services formerly operated by the provincial administration (since 1993) would be run by the Operadora Ferroviaria Sociedad del Estado (SOFSE).

[3][2] Services taken over by SOFSE included the following lines: Plaza Constitución to Bahía Blanca, Bariloche, Quequén and Bolívar; Olavarría to Bahía Blanca; Once to Toay, General Pico, General Villegas, Darregueira and Lincoln; Lincoln to Villegas and Pasteur; Retiro to Alberti and Junín; Federico Lacroze to Rojas.
