You can step inside (and perhaps even ride) a Key System bridge unit at the Western Railway Museum near Suisun City, which has its own electrified railway line!

You can step inside (and perhaps even ride) a Key System bridge unit at the Western Railway Museum near Suisun City, which has its own electrified railway line! Once upon a time, this line was part of an electric railway connecting Oakland and San Francisco to Sacramento. A hundred years later, electrification between Sacramento and the Bay is a long-term wish list item for Capitol Corridor. It is such a shame that the US allowed its passenger rail system to atrophy.
