The Cercanías division of Renfe was created in 1989 on the advice of engineer and transit planner Javier Bustinduy (es; 1949–2016), as part of a major effort to massively increase ridership, frequencies and hence attractiveness of commuter rail systems in Spain. Cercanías systems are gradually in the process of being transferred to the regional autonomous governments; the first such system to be transferred was the management of the former Cercanías Barcelona/Rodalia Barcelona to the Government of Catalonia and renaming to "Rodalies de Catalunya" in 2010. The Madrid Cercanías network was the target of the 2004 Madrid train bombings. The attacks, which killed 191 people in Santa Eugenia, El Pozo and Atocha stations, were the bloodiest terrorist actions in Spain to date.
