It was just last June that the Amtrak San Joaquin line received a 7th daily train, and now planning for an 8th daily is well underway. The current target, according to the San Joaquin Joint Powers Authority, is January, but I wouldn’t be surprised to see that slip a month or two.
The plan is to offer a “morning express,” with service between Fresno and Sacramento. Currently, all trains originate in Bakersfield, with 5 going to Oakland, and 2 to Sacramento. Riders can reach either location the full 7 times thanks to bus transfers.
