Back in 1991, I flew down to NAS Alameda to attend the shipboard firefighting class at NS Treasure Island; at the time, there were at least two (and possibly three) tracks as far west as 3rd Street, just before the line crossed Atlantic Avenue and ran north to the Oakland NSC Annex. The track leading onto the NAS itself was still in place, but was paved over as rail service to the base and the Naval Aviation Depot had ended sometime in the mid 80s. If you use Google Earth to look at the base, you can see where most of the tracks were, including the ones to the former locomotive and car repair shop, which is just east of Ferry Point Road and just south of Avenue G (it was actually used for maintaining all mobile equipment used on base; when I was there it was being used for maintaining rubber-tired equipment only) and the tracks for the rail cranes that once served the carriers berthed at the southwest corner of the base.
