Paul Gascoigne admitted assaulting rail station worker Jack Sherrington when he tried to assist after noticing Gascoigne was staggering towards the railway tracks.
The ex-footballer was travelling from Newcastle to London King's Cross but got off the train at Stevenage station.
He became abusive to Mr Sherrington and used the "c-word" repeatedly, Elaine McMillan, prosecuting, told the court.
Ms McMillan said Gascoigne grabbed hold of Mr Sherrington in the neck area - an assault which lasted a few seconds.
The court heard that Gascoigne had been in Newcastle visiting his ill father, who has a heart condition.
Gascoigne's lawyer Gavin Harris said he only consumed a small amount of alcohol due to a "combination of stress caused by worry for his father and acute pain from a hip operation six weeks previously".
Mr Harris said that because Gascoigne had not drunk alcohol for a significant period of time, the effects were stronger than would have otherwise been the case.
The court heard that Gascoigne's ex-wife and children were called to the station and in her sentencing, chair of the bench Carolyn Marsh pointed out that his 17-year-old son was "distressed".
The court also heard that Gascoigne was receiving "one to one" treatment for his alcoholism, which was continuing.
In a statement outside court, Mr Harris said: "He wants to publicly apologise for his actions that evening.
"He now wishes to be left alone to carry on with his recovery."
