When booking a north-bound trip on the Pacific Surfliner and the Coast Starlight, train 763 is the only Surfliner train offerred. It gets into LAX at 8:50am but the 14 doesn't leave until 10:25am. Any reason why I couldn't just take the later "express" train, currently numbered 599, which gets into LAX 9:35am? It would still give a 50-minute connection and (luckily) I've never been more than a half hour late into LAX on 599. Why does Amtrak do this?
