Britain’s High Speed 2 (HS2) rail project is now the world’s most expensive, with costs ranging from $93.44 billion to $112 billion AUD.

Britain struggling with costs of high speed railway project.

Britain’s High Speed 2 rail project is now ranked as the&nbsp;<a href="https://edition.cnn.com/travel/hs2-britain-expensive-high-speed-railway/index.html">most expensive in the world</a>.&nbsp;The first and only phase of HS2 is priced at between A$93.44 billion and $112 billion by the U.K. government.&nbsp;This breaks down to a staggering $665.6 million per mile.&nbsp;The US$128-billion California High Speed Rail in the U.S. is the only other rail project to come close to matching HS2’s costs.&nbsp;When it launched in 2012, it was with a projected overall cost of approximately $68.48 billion for almost 400 miles (643.738 kilometres) of new railway.&nbsp;HS2 has now been overseen by five different CEOs, seven chairmen, six prime ministers, eight finance ministers and nine transport ministers.&nbsp;Railway journalist Christian Wolmar says that the project was likely to fail from the start, with simple design flaws contributing to the rising prices.&nbsp;“A number of mistakes were made at the outset, including the decision to build the line for 400 kilometers per hour operation, 100 kph faster than the international norm,” he says.&nbsp;“There was also a lack of discussion over the chosen route, which could have followed existing highway corridors.”&nbsp;Rapidly rising construction costs, unexpected British political upheaval and permit issues have also been attributed as some of the many difficulties HS2 has faced.
