do they have that line back open for regular service, yet?
Yes. A day later than planned. Route was ready on Tuesday, 9-16-08, but the NTSB took it over for testing as part of its investigation into the wreck. Part of this involved running two UP locomotives and a Metrolink train face to face (point of impact), then slowly backing them to determine the point at which the trains would have been visible to each other, and how much time the crews had to react (about 4 seconds).
Metrolink Ventura County Line resumed truncated rail service from Chatsworth to Union Station (Chatsworth, Northridge, Van Nuys, Burbank airport, downtown Burbank, Glendale, LAUS) on Monday, 9-15-08. Buses were used to convey passengers from the Moorpark and Simi Valley stops. Passengers who would normally board at Montalvo (me), Oxnard, and Camarillo had to find alternative transportation.
Because Amtrak's Pacific Surfliners and Coast Starlight were not running on the 16th, my
Tuxedo Run, for which I had made reservations online prior to the wreck, was delayed by a day. Actually, the Starlight was beginning and ending at Santa Barbara, with buses connecting from L.A. No good for me, because although I coulda gotten the Starlight connecting bus at Oxnard, without the Surfliners running (or the Starlight south of SBA) I'd have no way home from Santa Barbara.
I called Amtrak early Tuesday morning for confirmation of the situation, and to make sure that whenever the trains resumed running there would be no problems with my reservations. Then Amtrak called ME, and we went over essentially the same ground. Difficult to say for sure, but I thought the agent sounded relieved that I was aware of the situation and didn't mind waiting for resumption of service. I'm easy!
Full route service on Metrolink's Ventura County Line was back by Tuesday afternoon, with Amtrak following suit on Wednesday. Coast Starlight Train 11 may have made it to L.A. on the 16th, but not sure.
