A 14-year-old boy who was thrown onto train tracks at Hawthorn train station yesterday said he is relieved his peers and other passengers were quick to assist him.

Cian Channon-Ling, who has autism, was walking home from school when a man allegedly threw him onto the tracks just before 4pm yesterday.

“He ran up to me and then he grabbed hold of me and pushed me off the platform… I was screaming,” Cian told 9NEWS.

“I was shocked, and angry, and I’m not going to forgive him for that.

“I was so relieved, I was like ‘thank god someone saved me’.”

Rossbourne High School student Matthew Rutledge rushed to his aid.

“He’s thrown him straight up in the air and he’s just gone flying onto the tracks,” Matthew said.

“I just grabbed him with some other guys and pulled him off the tracks.”

Cian suffered a broken arm, lacerations and bruising.

His mother, Michelle Channon, said the emotional wounds would be more difficult to heal.

“He is borderline severely autistic and for a disabled child to not be safe going home from school is, I think, rather shocking,” she said.

“I’d like to thank all the members of the public, and the staff and students from his school but this should never have happened.”

The alleged offender, Adam Reeves of Tullamarine, was held down by witnesses until police arrived.

Reeves was remanded in custody after briefly appearing in the Melbourne Magistrates' Court today charged with multiple offences including intentionally causing injury and committing an offence while on bail.

A 73-year-old woman was also hospitalised after allegedly being bitten and assaulted on board the train.

A 54-year-old man also received minor injuries.

The court heard he suffers from schizophrenia and would require medication while in custody.

Reeves is due to appear in court again on October 28.
