One woman was pulled to the ground before being kicked and punched and another needed hospital treatment in attacks in Ayrshire.
Onboard the 8.30pm Glasgow Central to Ayr train service on Thursday a woman was beaten by a group of four females.
She was pulled to the ground, kicked and punched repeatedly, police said. She was left with injuries to her face and head.
The suspects alighted at Kilwinning railway station while several fellow passengers came to the victim’s aid.
Later that night, at around 11.20pm, a group of four women assaulted another woman at Ayr railway station. The victim had to be taken to hospital because of her injuries.
British Transport Police detective constable Martin Graham said: “We are urgently appealing for witnesses following these two awful incidents. Thankfully, these incidents are rare, and this type of behaviour will absolutely not be tolerated on the railway.
“We currently are pursuing a positive line of enquiry for both these assaults, however we urge anyone who witnessed either incident or has any information to come forward.”
