Pencils have erasers. Computers have the undo command and the escape key.

If you had it to do over again, would you vote for the bullet train?

It was called the “Safe, Reliable High-Speed Passenger Train Bond Act” on the 2008 ballot, and it authorized $9 billion in bonds — borrowed money — to “partially fund” a high-speed train system in California.

The ballot measure required that there would be “private and public matching funds,” “accountability and oversight” and a focus on completing “Phase I” from Los Angeles to San Francisco to Anaheim. Bond funds could not be spent on the other corridors, like Fresno to Bakersfield, unless there was “no negative impact on the construction of Phase I.”

Today the estimated cost is over $68 billion, private and federal funds are not in sight, and accountability has been cut back — instead of two spending reports to the Legislature every year, only one report every two years will be required. And “Phase I” broke ground in Fresno.

Place your finger on the escape key and stand by. State Sen. Andy Vidak, R-Fresno, has introduced a bill, co-authored by Assemblyman Rudy Salas, D-Bakersfield, to put the bullet train before the voters again. If Senate Bill 3 (SBX1-3) can muster a two-thirds vote in the state Senate and Assembly, it will be on the June 2016 ballot.

The measure would freeze spending on the bullet train and direct unspent funds to the Department of Transportation to be used for roads, which would come in handy because California needs $59 billion just to maintain the freeways for the next 10 years. Gov. Jerry Brown has called a special session of the Legislature to look for revenue to fill the state’s transportation budget pothole after signing a “balanced” budget that left that item out.

The non-partisan Legislative Analyst’s Office offered some suggestions that illustrate the difference between what tax increases can raise and what the bullet train costs.

There are other options. The LAO says lawmakers could prioritize the budget to use money from the general fund to maintain and construct roads. Billions in cap-and-trade revenue, collected from fees now levied on gasoline and diesel fuel, could be used for highway projects that reduce traffic and improve mileage.

Additionally, $900 million that was loaned from state transportation accounts to the general fund could be repaid and used for roads. “Efficiency and effectiveness” could be improved by prioritizing cost-effective maintenance projects, increasing accountability and oversight, and examining Caltrans’ “capital outlay support” program to see if it is “operating efficiently.” Hint, hint.

The scrimping, saving and tax hikes needed to maintain the freeways can’t begin to address all the other transportation infrastructure needs, and we still have to pay for the rising costs of Medi-Cal, unfunded pensions and health benefits for state employees, and desperately needed water projects.

In 2008, the ballot argument for the bullet train promised high-speed rail “without raising taxes,” but it’s a shell game if tax revenue is spent on the train while taxes are raised for the roads.

Sen. Vidak’s bipartisan bill ought to have the support of every lawmaker. Voters deserve a chance to undo the bullet train and escape from this mess.
