Police want to speak to these men after raids on trains in Leeds.
British Transport Police released the images as part of an investigation into two incidents at a rail depot in Osmondthorpe.
In both incidents, at the Neville Hill depot, the trains’ catering areas were broken into.
In the first break-in, on July 22, nothing was taken. In the second, three days later, sweets and alcohol worth £400 were snatched.
PC Christopher McGlynn said: “It is unclear whether the two groups who committed these offences were working together, or if the same people were involved in both, but it is vital that we trace and speak to all of the people pictured to find out what they know.”
