It was in November last year that four men were charged with over 100 cases of grievous bodily harm.
The men documented the actual vandalism that took place during 2018-2019.
Three of them are now convicted of scribbling on trains in several places in the region.
Two of the men are sentenced by Attunda District Court to prison, one for one and a half years and one for one year.
The third man receives a suspended sentence and the fourth is released from suspicion.
They must also pay large damages, one of them of almost SEK 850,000, according to DN.
- The time is over when we saw between the fingers of this type of crime, says Kristoffer Tamsons, traffic region councilor, (M) to the newspaper.
The damage is an expensive deal for SL
The damage in SL traffic increased during the corona pandemic, something to which the traffic region council reacted strongly.
In recent years, SL has invested almost SEK 200 million in decontamination and restoration of public transport.
Mainly in the metro business.
The convicted men will appeal the verdict.
