London hoeowner Hero Granger-Taylor had started a legal case against the HS2 Ltd claiming that the design of HS2 Euston tunnel are unsafe. But her claims failed to convince the judge. Judge found HS2 Ltd's counter claim that the design of the tunnels is safe.

The homeowner's legal action against High Speed 2 were based on an engineer's report that planned the tunnels could damage her home.  The report was prepared by Colin Elliff, a specialist railway engineer who was brought in to assess the legitimacy of the Three Tunnels Design.

Mr. Elliff’s report claimed the Three Tunnels Design could cause a huge 10-metre high, 120-year-old wall to collapse into the new tunnels below or onto the existing West Coast main line, potentially crushing railway passengers. Report said that 'Evidence shows the unstable wall creating 130 tonnes per metre of pressure downwards onto the proposed 9m wide tunnel just 1.5m below'.

Now with this court ruling, one more hurdle is off the way of HS2 Ltd.
