The new SMART began electrical work from Schellville to Windsor in 2009. Reballasting and replacement of bad ties between Schellville and Windsor was completed by October 2009. Northwestern Pacific reopened the line and began operations in June 2011 over the section of track between Napa and Windsor, California. In July 2011 the first freight train delivered grain to Petaluma. Trains today on the NWP run from the Lombard interchange with the California Northern Railroad, up to Windsor. Service consists of about three trips weekly over the line. The railroad has hauled grain for dairy and poultry farms in Sonoma County, and lumber products out of Windsor and Schellville. Occasional maintenance of way work for SMART and car storage in Schellville have also been an integral part of NWP operations. At Napa, the railroad exchanges freight carloads with the CFNR in American Canyon.
