 Part of the Dumbarton Rail Corridor plans include a new connection between the Oakland subdivision (running generally north–south) and the Centerville line (running generally east–west) near Shinn Street, east of the Fremont Centerville station.Trains originating in Union City would enter the Shinn connection, turning right from southbound to westbound, and pass under the BART tracks before joining the Centerville line.Freight traffic would be rerouted from the Oakland subdivision to the parallel Niles subdivision, slightly to the east.
