The estimated cost of building 119 miles of bullet train track in the Central Valley has jumped to $10.6 billion, an increase of $2.8 billion from the current budget and up from about $6 billion originally.

The new calculation takes into account a number of intractable problems encountered by the state rail agency. It raises profoundly difficult questions about how the state will complete what is considered the nation’s largest infrastructure project with the existing funding sources.

The new estimate was presented Tuesday by Roy Hill, who leads the main consulting firm on the project, WSP (formerly Parson Brinckerhoff). Hill said the cost increases were mainly driven by problems including higher costs for land acquisition, issues in relocating utility systems, the need for safety barriers where the bullet trains would operate near freight lines and demands by stakeholders for the mitigation of myriad issues.

“The worst-case scenario has happened,” Hill bluntly told the rail authority’s board at its regular monthly meeting.
