Friends of the Earth is encouraging angry commuters to bombard the Government with complaints using text messaging. Friends of the Earth will convert the messages into emails and forward them to the Treasury, addressed to chancellor Gordon Brown.
It is part of its campaign for more investment in Britain's rail network.
"A lot of people use their mobile phones to have a moan to friends and family about a bad journey, and we're trying to encourage them to take their complaint directly to people who can actually make a difference,
said Tony Bosworth, transport campaigner for Friends of the Earth.
The campaign calls for a 75 per cent increase in rail funding financed by cuts in road-building and a ten-year programme of increases to fuel tax. Friends of the Earth will run a fundraising appeal in conjunction with the campaign, targeting its 80,000-strong donor-base.
