The Government's HS2 compensation scheme has been attacked by people living along the route who claim their homes and lives have been blighted.
Thousands of west London residents living above a tunnel where trains will travel at 225 mph have been told they will receive nothing.
Campaigner Lottie Jones of Ruislip Anti HS2 said her home was now impossible to sell.
"I think it's grossly unfair we are being discriminated against in urban areas as opposed to rural areas. There should be no difference in how the blight is recognised above tunnels," she added.
"Just because we've got tunnelling here doesn't mean we won't be disrupted and our lives won't be affected by HS2.
"Our houses are very much blighted and have been for three-and-a-half years, decreasing in value and they're nigh on impossible to sell."
