A third boy has been charged over an incident at Howth Junction train station in Dublin earlier this year.
CCTV footage emerged showing a 17-year-old girl falling between the platform and a stationary train on 1 April.
She was helped back onto the platform by her friends and staff.
Investigating gardaí obtained directions from the Director of Public Prosecutions and arrested two boys aged 16 and 17.
They appeared at Dublin Children's Court on Tuesday and were granted bail with strict conditions.
Both are charged with violent disorder by using or threatening to use violence with two others, causing another person to fear their safety.
The 16-year-old is also accused of assault causing harm to the girl.
Today, gardaí arrested the third boy, aged 17, and charged him with violent disorder at the station.
The teen, accompanied by a family member, appeared before Judge Paul Kelly at the Children's Court and was ordered to obey bail conditions.
He told the boy to have no contact with the girl and her family or his co-defendants. However, unlike the other boys, he was not barred from all DART stations.
Judge Kelly warned the no-contact condition includes the use of messages, third parties or social media.
Next month, the boy will face a preliminary hearing with the co-defendants to consider their trial venue.
The DPP directed "trial on indictment" in the Circuit Court, which has broader sentencing powers.
However, because they are juveniles, they can have a "Section 75 hearing". The procedure allows them to plead with the Children's Court to retain jurisdiction by considering age, level of maturity, and any other relevant factors.
The prosecuting garda must provide disclosure of evidence to the defence.
Judge Kelly warned the boys they must be of good behaviour and that they risked having bail revoked if they broke the terms.
The teens, who have been granted legal aid, have not yet indicated how they will plead.
