The Church of England has called for a change to the HS2 Bill.
Its Archbishops’ Council submitted a petition to Parliament regarding treatment of burial grounds and human remains on the route.
The Church of England said burial grounds at Euston, Kensal Green, Stoke Mandeville and Birmingham would be disturbed by the £43bn project to build the rapid rail link.
It added: “The provisions of clause 26 and Schedule 19 do not make adequate provision to ensure that during and after the removal of human remains they are treated in a decent and reverent manner or that they are subsequently reinterred in consecrated land.
“Nor do they make adequate provision to ensure that any monuments that are removed are disposed of in a suitable manner.”
Birmingham’s city council and airport were among several organisations to make a formal bid for changes to the HS2 Bill last month.
The Bill passed its second reading in Parliament in April.
