Pros: Good scheduling, beautiful scenery,. Cons: It would help if there was more frequent service on this line, so it would fit better into passengers' schedules. However, on this trip, the scheduling worked out fine. Also, connection to San Francisco was awkward. We took Caltrain from San Francisco to San Jose on the outbound trip and my wife drove from San Jose to San Jose to pick us up on the return trip (much quicker than using Oakland in either direction).

Pros: not driving for 5 + hours. not putting wear and tear on my car. not eating junk food along the highway. Cons: two options daily for travel...leave at 4pm and arrive at 11pm so as not to lose a work day. Tips: the dining car is a must.
