People living along the route of the new high speed rail line - HS2 - in Oxfordshire and Buckinghamshire say the project has cut property prices by thirty per cent and many homes are now blighted and impossible to sell.
A series of roadshows are being held to explain how much compensation the Government plans to give them.
Over the next few days public exhibitions are being held at Calvert, Wendover and Brackley starting today.
A giant white elephant will be outside the events as local people protest against the scheme.
HS2 will run from London to Birmingham cutting across the Oxfordshire and Buckinghamshire countryside.
The Government say the scheme is generous and people in the direct path of the scheme will get the market value of the property and ten per cent on top.
They say they have set up a special hardship fund to buy homes residents find difficult to sell.
But campaigners say the compensation for those who live further away from the route - but meat still be badly hit - is unclear and derisory.
They say many will have to wait for years before they get a final decision on how much compensation they are given.
