Seems Barcelona’s commuter trains are not as good as they could be:
The other thing everyone’s talking about is the awful Barcelona commuter train system; there was another massive delay yesterday on two of the suburban train lines. That makes about twelve major screwups on the Renfe commuter trains this year so far. This time a bunch of passengers got pissed off and blocked the train tracks at Martorell, thereby holding things up even more, of course. That’s what happens when the government runs the trains or any other industry that should be in private hands.

Commuter action is not unknown. In the 1970s, unhappy commuters smashed up a station in Tokyo. A few years later the company was privatised.
