On January 20, a fatal derailment in Catalonia, just two days after the high-speed rail disaster in Andalusia, led to unprecedented levels of disruption, with the entire Rodalies network suspended several times due to safety concerns. 

But the problems with Catalonia's rail network stretch much further back.

In this episode of Filling the Sink, Lorcan Doherty and Cillian Shields examine Catalonia's Rodalies commuter rail network: decades of underinvestment, the recent Gelida accident and subsequent strikes and shutdowns, and the planned transfer of management from Spanish to Catalan authorities.

Francisco Cárdenas, UGT union representative for Renfe workers in Catalonia, explains how years of neglect and insufficient maintenance have created a network that train drivers no longer feel safe operating.

Rail expert Joan Carles Salmerón, director of private research center Terminus, provides his diagnosis of the structural weaknesses in Catalonia's rail infrastructure, including a disproportionate focus on high-speed lines at the expense of local commuter services.
