Premier Nathan Rees announced the ``tough new laws'' this week following reports vandals were jamming rail signals before attacking stationary trains.

He said regulations would be amended so that youth justice conferences would require vandals to agree to either cleaning up graffiti or other community service work, paying compensation or participating in training or education programs.

Mr Rees said the Government was also planning to overhaul prevention and clean-up measures and work with councils on new ways to tackle the problem.

The police commissioner would order all local area commands to target the problem and Office of Fair Trading officers would blitz spray can retailers.

Opposition transport spokeswoman Gladys Berejiklian said every premier and transport minister in the past 14 years had promised such a crackdown.

Since 1995, the Government has created seven task forces, action teams or pilot programs.

Cr Kelly said the initiative followed a campaign by six beachside councils, including Sutherland, to seek urgent reforms.

However, only first-time offenders should be given the option of education and training.

Cr Kelly said questions to be answered included who would pay for the courses or clean-up, and what would happen if offenders were not classified as youths.
