Campaign for Better Transport called in Forster to create the brand and website to support its Fair Fares Now campaign.
Forster project director Gillian Daines said: 'We were passionate about working on this campaign because it's an issue that affects so many people.
'Campaign for Better Transport already had a strong PR strategy in place for its campaign and needed an eyecatching and engaging brand and website to give people who wanted to support Fair Fares Now a call to action.'
The new cost of some season tickets equates to about 20 per cent of the average UK salary, according to the Campaign for Better Transport.
Fair Fares Now launched on 4 January at London's Charing Cross station, where supporters asked members of the public to sign up to the campaign, write to the Government and take part in protests.
