A RAIL worker has been slammed by his bosses for crippling a train network by looking at PORN in the office.
Investigators found there were so many viruses infecting the rail network's computers in Gavle, Sweden, they were incapable of running trains safely.
His outraged bosses gave the signalman an official warning saying that thousands of passengers and hundreds of cargo trains were put at risk by his porn addiction.
A report into the scandal also said the 52-year-old worker regularly missed his shifts at the network controls because he was too tired to work after being up all night ogling saucy internet images.
One frustrated driver reported that the man had slept soundly at his post while he awaited permission for his train to enter the station.
But union bosses claim the official warning was "too harsh".
One said: "A letter would have been more appropriate."
