So yeah, "bad luck". Seems to me that the improbability of it being an accident is matched by the improbability of it being sabotage.
“Bad luck” would also be the description some have used for the commuter train accident in Barcelona. The retaining wall collapsed just as the train was passing underneath it. Officially, the cause of the collapse was heavy rain, but perhaps the vibrations from the approaching train precipitated the collapse of the already weakened wall? However, I think one can also speculate that it could be a coordinated attack.
There were two other train accidents that went largely unnoticed by the media because there were no fatalities or injuries.
One occurred on Saturday in Tortosa, Tarragona:
El suministro eléctrico se ha reparado entre la noche de ayer y la madrugada de hoy. Ello ha permitido que los trenes puedan llegar o salir de la capital del Baix Ebre con normalidad este domingo

[...] a series of explosions caused by a fallen overhead wire hitting the roof of an empty train car.
Another on Tuesday, the same night as the two accidents in Catalonia, the roof of a tram was on fire in Valencia:
Las autoridades competentes descartan un posible fallo en la catenaria como origen del incendio

A spark ignites the roof of a tram and forces traffic to be cut off on Tarongers Avenue. […] The competent authorities rule out a possible fault in the catenary as the cause of the fire
In summary, five incidents in four days.
It is true that there is talk of significant investment and care being taken with the rail network, but at the same time, for years there have also been numerous complaints from users and train drivers denouncing the poor state of the infrastructure (delays, power cuts, derailments, rattling trains).
If we add to this the fact that the Ministry of Transport is involved in several cases of government corruption, the feeling among many Spaniards is that the money is not being invested wisely and is being squandered, and that those in charge are incompetent. Just a few names:
-The former Minister of Transport (Ábalos) is in prison.
-The former president of ADIF (Railway Infrastructure Administrator) is charged with five crimes.
-Koldo, a security guard by profession and Ábalos's alleged “fixer”, was appointed as an advisor to RENFE (Spanish National Railway Network). He is now in prison.
-Jéssica, Ábalos's escort, was appointed as deputy director of ADIF (Railway Infrastructure Administrator).
Many people had a feeling that something bad was going to happen with the trains.
If someone wanted to attack the Spanish government, the Spanish railway network was its weakest link. Except for leftists, everyone will point to the government as the culprit. OSIT
