Pacific Surfliner Trip from LA to San Diego (2:45 hours) I know the WHOLE thing would be really long (it's nice in TSC though) but even parts of it would be nice. It would connect with the San Bernadino and Antelope lines. Get to use a couple different locos depending on the era (the "American Vectron" would be neat if it were most recent. A diesel Vectron basically would be something different!) Those views though.... Throw in route hopping for a "north" and "south" halves of the line and it'd be beautiful.
