From [2] (machine-translated):

> The accident occurred near Atocha station, on a curve where signage indicates a speed limit of 45 kilometers per hour. However, sources consulted by this newspaper assert that the train, out of control, easily approached speeds of 90 to 100 kilometers per hour, ultimately resulting in the derailment. [...] Two mechanics who were inside the wrecked train escaped injury.

Any indication they deliberately derailed the train?

Edit: yes! E.g.

(Says the train was diverted away from others, rather than deliberately derailed maybe)
