The California Department of Transportation wants to build a new railyard to clean, restock, and maintain Amtrak trains.

The two sites being eyed for the new railyard are both near the American River, near or partially on Sutter's Landing Regional Park.

Both sites are being eyed by developers looking to build homes -- one would include shopping, the other has a park and walking paths. The city hopes to learn more about the proposed railyard on Monday.
