history. Without sufficient cash reserves to finance the excavation the railroad announced a fundraising campaign on June 7, selling lifetime passes and seeking private donations to meet a goal set at $300,000, the estimated cost to remove the blockage and repair the tunnel walls. The announcement explicitly stated that if some manner of external funding was not secured it would have no option but to cease operations permanently. On June 19, Save the Redwoods League announced an offer to pay the amount required to meet the fundraising goal in exchange for a conservation easement along the track's right-of-way. The acceptance of the offer allowed the railroad to resume full service in August 2013. Tunnel No. 1 was once again closed in 2016 after sustaining damage from the 2015–16 El Nino, but the railway was left in a better position, having equipment at the Willits depot to allow the running of half-routes to the Northspur Junction and back (which was not the case during the 2013 crisis); trains from Fort Bragg are limited to running only to the Glen Blair Junction (one hour round trip) before returning to the depot, officially called the "Pudding Creek Express." No announcements regarding the status of Tunnel No. 1 have been made since 2015, though the railroad is fully committed to its reopening. Both tunnel collapses were related to the hillside, which has a history of instability dating back to its construction in 1893. Railbike tours began in 2018 as a response to the tunnel closures, with multiple other tourist lines around the country introducing their own railbike experiences after the California Western's railbikes proved very popular. The railroad applied for a United States Department of Transportation BUILD grant in 2018 to fund tunnel repairs and replace over 30,000 ties made of chromated copper arsenate installed by Kyle Railways; this grant was denied in February 2019, but the request was reportedly in the top-third of those sent, and the Department of Transportation encouraged the railroad to re-apply. The railroad also planned to address deferred maintenance issues, and upgrade its tracks for commuter and freight service in anticipation of the reopening of the Northwestern Pacific to Willits and the potential extension of Sonoma–Marin Area Rail Transit (SMART) to Willits. Had the grant been approved, reconstruction of Tunnel #1 would have begun in 2019 and be complete by 2021, while tie replacement would have lasted until 2024.
