Public Transport Safety Victoria documents released last week show seven of the 62 incidents were reported at Hughesdale, Oakleigh and Clayton stations.

In one incident at Hughesdale station at 11.45pm on June 15, authorised officers were "set upon by two males - knife, scissors involved".

Another report stated a male and female were assaulted by five other passengers at Oakleigh station at 1pm on April 20.

Statewide, 330 incident reports were recorded, including two incidents on the Glen Waverley line.

Connex spokesman John Rees said the situation was a little better than what had been painted.

"More than 600,000 people use the metropolitan rail service daily and we run about 200 services a day. When you think about those sorts of numbers, it puts it into perspective.

"That there are any incidents is unacceptable. Our target is always zero, but violent people didn't become violent because they were waiting for a train or they didn't want to pay for a ticket."

He said Connex would work closely with police to reduce the number of incidents across the board. "We'll also ask the community to get involved. It's their train service and whether it's rock throwing, vandalising or graffitti - all these incidents affect the service and affect our customers."

A spokeswoman for Transport Minister Lynne Kosky said crime on public transport had fallen 36 per cent since 2001-02, while nearly 400 extra frontline staff were deployed on train and tram services.

"But any level of violence on our transport network is concerning, which is why the Brumby Government continues to work closely with train and tram operators to improve safety across the network."

Opposition public transport spokesman Terry Mulder said the number of assaults was unacceptable and unruly passengers were unsettling to many passengers.

"Melbourne's 300,000 daily rail travellers who make a return trip are uncertain about whether their trip will be incident-free."
