Is there a train from the museum that will take you to San Franscisco and back for the day?
No, this museum is not a working railroad. However, the Amtrak to the bay is located about 1/2 mile from the Museum...and that will get you to/from SF in one day. Uber/Lyft from museum to Amtrak is only $7!
Sacramento Amtrak station is a 5 min walk from the Museum where you can get a train to San Francisco it takes around 2hr 20 min each way.
Amtrak Station, 401 I St., is a short walk away from the Sacramento RR Museum. The train runs frequently from Sacramento to SF, costing an adult $33, taking about 2 1/2 hours. The train stops in Emeryville and there is a bus bridge across the Bay Bridge to the SF Terminal. Old Town, where the train museum is located, has many restaurants to choose from as well as horse drawn carriage rides. Well worth spending the day in Old Town Sacramento, including the museum 1 hour train ride up the track for a bit and return. But, currently this is only offered on the weekends.
There is a train called the Capitol Corridor that runs several times during the day. A great ride to a great destination.
No but just down the street there is an Amtrak station that has trains to SF and back.
As mentioned above the train at the museum, which only runs on weekends, just travels a few miles up and down the Sacramento River. However it is a short walk from the museum which is located in the Historic Old Town Sacramento to the recently restored Amtrak station and there are several trains daily from SF to Sac and back. Besides the world class RR museum right next to it is the Sacramento History museum as well as several other great museums in the area, including the oldest are museum west of the Mississippi river. Don't miss the torus at the State Capitol either.
Additionally, there is a train called the Sacramento River Train, which runs along the river between West Sac and Woodland. It isn't a train you would take to get anywhere, it is more of a local sightseeing attraction sort of train. They have different themes for different times of the year. When I went, they stopped the train for included picnic lunch along the way, and stopped again for a Wild West shootout reenactment performed by actors in costume, it was a lot of fun! Great for kids or anyone who just loves trains!
it is pretty much a static museum other than a brief train ride along the Sacramento River for the tourists. For that, you would need to contact Amtrak I imagine.
