Police are keen to speak to these men following two sexual assault enquiries which remain unsolved in Redbridge.
An appeals gallery has been launched by police to identify the men.
The first man is sought in connection with an incident on June 13.
Police want to speak to the second man in relation to an incident on May 19.
Chief Superintendent Matt Bell, roads and transport policing command, said: “Transport crime is at its lowest level ever, however, any crime is one crime too many.
“We need the public’s assistance to identify offenders and we are making this easier for them through the provision of an on-line gallery of CCTV images.
“I urge the public to regularly view this gallery.
Ch Supt Bell said: “If they have any information please report it to us so we can trace and arrest offenders who commit crime on London’s transport network.”
If members of the public have any information about the people featured they should come forward by either contacting police direct on 0203 054 5500 [voicemail messaging], or by contacting Crimestoppers anonymously on 0800 555 111.
In both instances please quote the reference number on the image.
