> Maldita.es is founded by ex-employees of La Sexta, a TV channel known to be politically aligned with the socialist party

In this particular article they were fact-checking a wrong claim made by the socialist party, to me that shows that besides their alignment, they care about fact checking information. They also mention that the last three development plans were developed by PP ( People's party ) -- if they're aligned with the socialist party, why are they mentioning this and leave the socialist party "in a bad light"?

In regard to the state of the railway network, I totally agree with what you mentioned. Thought corruption will inevitably occur and doesn't mean that the persons above are aware of it nor that the socialist party is intentionally cutting funds. Nonetheless, totally unacceptable.
