The impacts on Niles include increased train traffic, significant change in the alignment of train traffic, noise, vibration, air pollution, traffic impacts at at-grade crossings to name a few. For example according to the Project Study Report the number of trains that use the Oakland Subdivision trackage which runs behind the Hacienda Gardens and Rancho Arroyo neighborhoods would increase from approx 6 to 250 trains / week. These would all be passenger trains. For the Niles Subdivision trackage which runs close to Mission Blvd. and across Nursery Ave. the number of trains would decrease from 92 to 61 trains / week however they would all be freight. While not specifically in Niles the Centerville trackage through central Fremont would increase from 118 to 257 trains / week.
All of these matters and others need to be addressed in an Environmental Impact Report / Environmental Impact Statement that was scheduled to be issued as a draft in September 2008, however it appers that issuance may not occur until the end of 2011. The project staff are building into the Dumbarton Rail Plan how it fits with the Regional Rail Plan, Altamont Corridor plan and the High Speed Rail Plan.
One element of the Dumbarton Rail Project that is independently going forward at a pace much faster is the Capitol Corridor initiative which is outlined in a separate page on Niles Community Unity. The Capitol Corridor initiative has what might be termed a dual identity from a project standpoint since it is one segment of the Dumbarton Rail (Segment G) and a stand alone project to increase passenger service from Oakland to San Jose.
The Capitol Corridor initiative is starting negotiations to acquire the Right of Way for trackage which parallels the BART tracks from Union City to Niles in order to accomplish its objectives.
