She came away with a bite mark on her forehead and bruising to her face after the incident, which happened at 16.40 on Saturday, 2 June.
PC Nigel Maggs, an investigating officer with the British Transport Police, said:"This was a nasty incident which left the victim injured and in some distress.
"It was a frightening experience for the girl, who did not know her attacker.
"Behaviour such as this is completely unacceptable and will not be tolerated on the rail network.
"It is essential that we identify the person responsible for this attack, and I urge anyone with any information to contact police."
In a bid to locate the man, CCTV pictures have been released. PC Maggs added: "Officers have identified a man they would like to trace in connection with the incident.
"Enquiries have been ongoing to locate the man but these have so far proved fruitless.
"Therefore, I am today releasing a CCTV image of this person, who I believe will have information which can assist the investigation."
The girl boarded the train at Pontypridd, while the man is believed to have got on at Cwmbach.
He was wearing a black Nike T-shirt and a black cap, and had a Mohican-style haircut.
