I have been using public transportation for almost twenty years in the Inland Valley and beyond. I previously have been skeptical about the SBX project and not a big fan of the Rail to Redlands project. However the Gold Line extention project has some cards up its sleeve to do better things than the other two projects.
People can easily reach Ontario Airport instead of taking a taxi, park their vehichle for several days or have someone drop them off. People can reach Pasadena, Azuza Pacific University, Union Station, China Town and East Los Angeles.
The only issue is funding. San Bernardino County officials are stating that this is a pet project for the San Gabriel Valley people in Los Angeles County and why should San Bernardino County people pay for this back in 2014 in a San Gabriel Valley Tribune article which the executive director of SANBAG stated that.
Los Angeles County residents and shoppers do pay an extra cent sales tax to pay for projects such as the Gold Line. However since the Gold Line is not entirely in San Bernardino County, perhaps a fourth of a cent increase would be added to fund Omnitrans and the San Bernardino County portions of the Gold Line. To protect taxpayers, there would be a provision that increases in the sales tax would have to go to the voters.
Another option is to add a small surcharge to airline tickets. Fifty cents for flights under 200 dollars, and 1 dollar for flights over 200 dollars.
State and federal funding would also be critical for a project like this to break ground in the next decade as well. Most people would rather see local light rail over the bullet train boondoogle if we had to choose a transportation project to fund.
Personally I would rather see the Gold Line extention over toll roads.
