I first thought of Spain’s terror group, but this doesn’t seem to be that?

That would be the Basque separatists. The train seems to have derailed because it was going too fast.

I seem to recall that the Basques are very targeted when committing terror acts. They do not attack random people.

Don’t forget the Al Qaida attack on the trains in Spain which got blamed on the Basques. The voters responded by electing a socialist government.
