Hundreds of commuters wore cattle masks as they boarded their trains in an angry protest against unreliable services and rising fares.
Campaigners gathered at 20 stations across the South West and handed out ‘fake tickets’ for passengers to display their displeasure at the service provided by First Great Western.
There was standing room only on the Bath Spa to Bristol Temple Meads service after 40 passengers brandishing the special tickets were allowed through barriers.
Peter Andrews, one of the leaders of the More Train Less Strain group, said: ‘We feel at last our message is beginning to get through. The First Great Western service is appalling.
‘Have a look around, no one can sit down.’
Comedian Dom Joly boarded the train to support the campaign.
First Great Western has said passengers will start to see improvements in its service soon.
