Update on Coast Starlight wifi
Was just on the Seattle-Los Angeles Coast Starlight. The wifi was operational and consistent in the Parlor Car. That car, by the way, is only accessible to riders who've opted for the extra-cost sleeper option (highly recommended and cost-justifiable for this 38+ hour trip!). Those expecting free wifi train-wide will be in for a disappointment as the signal is not intended to cover the entire consist. I did notice that access was provided via a box stock Verizon JetPack 4620L, which struck me as unusual. Hopefully Verizon's waived their $15/GB charge for overages as otherwise this'd be a VERY expensive - and silly! - way for Amtrak to provide internet service!
