Key facts about the rail crash in Spain: What is known so far about the collision?

A train collision in Toledo, Spain, has resulted in at least 30 fatalities among 544 passengers. The incident involved two trains, one from Renfe and another from Iryo, which collided early Wednesday morning. Initial reports suggest human error may have contributed to the crash, as a Renfe train was mistakenly given the go-ahead to proceed while the Iryo train was stationary on the track. Emergency services have been deployed, and a judicial investigation is set to begin. Train services on the affected routes have been suspended indefinitely.
