Up to 30 people suffered breathing problems, sore eyes and throat irritation after the attack in south-east London - one person needed medical treatment.
Officers believe a noxious substance, either a CS gas canister or pepper spray, was used by the youths.
CCTV footage from Penge East railway station revealed one of the gang stared at passengers and drew his finger across his throat after the attack.
Detective Constable Vanessa Cottington said police want to trace two white men and a black youth on a bicycle.
She said: "About 20 to 30 passengers on the train suffered the effects of the gas, which was believed to be similar to pepper spray.
"CCTV footage shows the youths boarding the 3.52pm Victoria to Orpington service on Friday July 20.
"The three youths are then seen leaving the train at Penge East Station, and as the doors were closing one youth standing on the platform is captured on CCTV reaching his hand into the open window of the carriage.
"It is believed that he then sprayed a noxious substance similar to pepper spray into the carriage.
"As a result of the incident several passengers reported suffering the affects of the gas, with some having breathing difficulties and irritation to the eyes and throat."
