A man slapped a worker at Derby train station after he was kicked off his train home.
Kristian Harrison became angry with her when he was asked to leave the train to Chesterfield, his home town.
Harrison, 34, rushed over to her and slapped her on the back and shoulders.
The autistic man, of Kirkstone Road, Newbold, pleaded guilty to assault and was fined by the court.
Peter Bettany, prosecuting, said: “The victim says that on March 15, she was working at Derby Midland Railway Station.
“A little before 7.45pm she saw a man who she did not know on platform one. He appeared to be drunk and he went out on to the platform saying that he was drunk.
“He got very close to the platform edge. The worker approached him and asked if he was alright and if he needed anything to get home. He said he wanted to get back to Chesterfield.”
Eventually the train arrived at the station and Harrison got on, but as he was being loud and aggressive he was asked to leave.
Mr Bettany said: “The victim then saw the defendant running towards her saying that it was her fault. She turned away from him and felt his hand slap her back and shoulder.”
The victim suffered no injuries from the attack aside pain.

Southern Derbyshire Magistrates’ Court heard how Harrison had drunk around six pints of lager before the attack.
He has many previous offences including some for assaulting emergency workers, criminal damage and threatening behaviour.
It was also heard that he has been diagnosed with Asperger Syndrome which makes communication more difficult for him.
Jonathan Greenhill, mitigating, said: “This I think is a concoction of the fact that Mr Harrison has difficulties, which when you spend any time with him you appreciate more and more.
“He felt that the lady had something to do with him being asked to leave the train.
“When he saw the incident on CCTV he was embarrassed and ashamed. He was very, very remorseful.”
Magistrates handed Harrison a total of £117 to pay to the court.
This was made up of a £60 fine, compensation of £25 to the victim and a victim surcharge of £32.
