Town say fans engaging in antisocial behaviour will face bans and that they are working with British Transport Police after receiving complaints in relation to incidents on the railway network following Saturday’s game at Peterborough.
As previously reported, police were called to what they described as "a large disturbance” at Peterborough station involving fans of Town, Newcastle United and Norwich City which led to seven arrests.
Earlier that week, both supporters and the club had condemned racist chanting by a small section of the Blues support at Luton.
Regarding the incidents after the Posh match, Town say they have acted on concerns raised by Town fans and members of the public.
"We are working closely with the police on a number of incidents and we will see what evidence materialises,” club secretary Stuart Hayton told the official website.
"We have said before that our fans are among the best behaved in the country and we are talking about a small minority here but there have been incidents reported to us recently that we have to act on and we will.”
A club statement added: "Any supporter showing antisocial behaviour can expect to receive a club ban, with the possibility of police taking action that could result in court proceedings and football banning orders being issued.
"Town supporters can report any incidents which make them feel uncomfortable whilst travelling to and from games by texting British Transport Police on 61016 or calling 0800 40 50 40.”
