Two high-speed trains collided near the village of Urla in Castilla-La Mancha, south of Madrid, on October 28, killing at least 64 people and injuring more than 80, 50 of them seriously. One train was believed to be stationary when the other hit it from behind, on the same line where 46 people died in January. Transport minister Oscar Puente says the automatic signalling failed and a controller let a train restart at speed toward the stalled one; audio now suggests the controller knew the line was blocked five minutes before the crash. Hundreds have demonstrated outside Madrid's transport ministry, and train drivers are staging a 24-hour safety strike planned before the crash.
