The National Trust will today outline its concerns about the impact of the new high speed rail line from London to Birmingham.
The Trust fear HS2 will badly impact historic land and property along the route in the Thames Valley.
The Government are proposing to build the £32bn scheme that would run near Wendover, Aylesbury and north of Bicester and Banbury. They say it would boost the economy and create thousands of jobs. Those against say it has no economic case and will be bad for the countryside.
Today the grounds of one property, Hartwell House at Stone, will open to allow members of the public to see how it will hit.
The National Trust say they do not oppose high speed rail but if HS2 is to go ahead more measures must be taken to ensure the impact of noise and visual intrusion is reduced.
HS2 say that so far they have consulted with 55,000 people and organisations along the route and changes have already been made. They insist they want to continue to work with those who will be affected to do all they can to minimise the impact.
In our region four areas are cause for concern: Claydon, a country house in the Aylesbury Vale; Waddesdon Manor in the village of Waddesdon; Combe Hill near Wendover; and Hartwell House.
