Mother-of-four Tanya Oakley thought she had heard a 'disparaging comment' at her expense as she travelled on a train at Birmingham Moor Street after a night of clubbing.
The 26-year-old believed a group of people were 'laughing at her'.
She went down the carriage and swung at one woman's mouth and yanked the hair of another, Birmingham Magistrates Court was told.
Oakley, of Best Street, Cradley Heath, was given a conditional discharge lasting 18 months after admitting two charges of common assault on November 2 last year.
The train driver was disturbed by the fracas and went back into the carriage to tell everyone to calm down, before telling those involved to get off.
The group including the two women Oakley attacked - who had also been out clubbing- got off the train but Oakley's group jumped back on to continue the journey.
Oakley later saw a CCTV picture of herself which had been released to the media by police and called officers.
Mr Jonathan Purser, prosecuting, said: "In interview she said she left the club with her friends at 5am and on a scale of 1-10 of intoxication, she said she was about a 10.
"She accepted boarding the train, she accepted swinging at one of the girls who was sat down.
"She said she was restrained by the other people in the group. She fully accepted everything from the statements of the injured parties.
"At the conclusion of the interview she said she was ashamed of what she had done.
"She was shown CCTV footage in which she identified herself and said she appeared like a bully and horrible."
Mr Darryl Foster, defending, said Oakley was 'distraught' at what had happened because she was not a habitual drinker and had 'just gone to let her hair down' for a night.
Oakley was also ordered to pay £25 compensation to the two women she assaulted, as well as £50 costs and a £15 victim surcharge.
