SYDNEY'S beleaguered rail network is a potential death trap for children and babies, with a child a day falling on to the tracks.

The figures prompted RailCorp to take the unusual step of handing out bracelets to children warning them to be careful as they attended Wednesday's State of Origin match - as well as flooding Olympic Park station with extra staff.

Internal RailCorp safety logs revealed that 68 people fell on to the tracks or between the train and the platform from March 18 to April 18 this year.

Distressingly, 32 were children.

The number of falls was more than double those of other months and were driven up by families travelling to see the Royal Easter Show.

They include a horror 48 hours in the middle of the school holidays in which seven children fell, almost all at Olympic Park. On Saturday, April 10, there were three falls in less than 80 minutes.

RailCorp chief operating officer Andy Byford said the agency had reacted strongly to the spike by putting in extra measures at big events and especially targeting children.

"It's very unusual to have that many. I wasn't very happy about it and I insisted we strengthen arrangements," he said.

Mr Byford said that at no stage had a train moved after a child had fallen.

There were also a number of cases of drunk people falling on to the tracks and even people climbing down to retrieve something they'd dropped.

RailCorp workers also had to deal with 27 fires over the period, many of them deliberately lit in carriages.

There were also at least 25 assaults and staff were spat on, or in one case vomited on, while attempting to help passengers.

The figures also include the tragic case of the worker killed on the tracks at Kogarah Station on April 13.

Another RailCorp staff member was caught crossing rail tracks without wearing safety gear the very next day.

There were several security scares, including a bomb threat at Town Hall station on March 30 and another one at Hornsby, as well as rail detonators activated by drivers wrongly entering zones where people may be working.

There were also incidents that were downright bizarre. In one case a red-bellied black snake was found at Riverstone Station.

In another a runaway cherry picker went on a rampage at Cronulla. One man was arrested for carrying a bow and arrows on to a train. It later emerged he was on his way to an archery competition.

Another person claimed to have been injured by a ticket barrier. CCTV footage later proved he had not inserted a ticket.
