the Dumbarton Rail Bridge swing span with a new bascule span, with the option for remote control from the Caltrain operations center or local control; the report also proposed replacing the Newark Slough Bridge swing span with a simpler steel girder swing span under local control, normally left closed to prioritize rail traffic over marine traffic. In addition, the Oakland subdivision would have to be purchased from Union Pacific, and UP indicated they were unwilling to sell only a portion, preferring to sell the entire right-of-way from Oakland to Fremont. The 2003 Project Study Report proposed constructing a new rail bridge across Alameda Creek for freight service over the Niles subdivision when Capitol Corridor passenger traffic was moved to the Oakland subdivision. However, this was seen as an illegal gift to Union Pacific from some citizens. A May 2005 community meeting attracted overwhelming opposition from Fremont residents living near the proposed new routing of Capitol Corridor and Dumbarton Rail trains. Public meetings were held in November 2006, attracting mild support and residents echoing the same noise concerns from the May 2005 meeting. Menlo Park residents who had bought houses near the 1910 tracks (which had not seen rail service since 1982) were concerned about the possibility of train noise and potential freight use, despite Dumbarton Rail Corridor plans for the use of only passenger trains. By March 2006, the estimated cost had increased again to . The 2006 Environmental Phase 1 report studied four alternative rail alignments and two alternative bus services to determine the most feasible options. Costs nearly doubled to by October 2006, driven partly by inflation and partly by the increased cost of construction. Other sources cited the delayed environmental review process. With the increase in costs, the Dumbarton Rail Corridor now faced a significant funding shortfall, since no new funds had been identified since the passage of Regional Measure 2 in 2004. In 2007, two more alternatives were studied for the DRC. Both called for the separation of freight and passenger traffic. Alternative 1 looked at a rehabilitated low-level single-track Dumbarton Rail Bridge, while Alternative 2 proposed a new high-level (fixed) double-track rail bridge. Based on projected ridership, a blend of both alternatives was proposed, retaining the low-level single-track drawbridge as marine traffic was expected to remain light. 2004–2014: Regional Measure 2 funding Regional Measure 2 (RM2) was approved by a majority of Bay Area voters
