two summer excursion trips between Sandpoint, Idaho and Billings, Montana, including stops at the Livingston Depot. On May 18 and May 19, 2007, SP 4449 made another appearance with UP 844 in the Pacific Northwest for the "Puget Sound Excursion", on BNSF Railway tracks from Tacoma to Everett, Washington, round-trip. On March 24, 2009, it was announced that No. 4449 would attend Trainfestival 2009 in Owosso, Michigan from July 23–26 with an all-day excursion planned on the 23rd and 24th and a photo run-by planned for each trip. The engine was then placed on display for the rest of the event. The historic 2,500-mile move from Portland to Owosso was arranged by the Friends of the 4449, Amtrak, Steam Railroading Institute of Owosso and the Friends of the 261. The Milwaukee Road 261 organization loaned some of its first-class passenger cars, including the former Milwaukee Road Super Dome #53 and the Cedar Rapids Skytop Lounge to join the 4449 and for other excursion trains at the festival. The train left its home at Brooklyn Roundhouse on July 2 and left the city of Portland the following day, on July 3. It returned to the city of Portland and Brooklyn Roundhouse on October 20. In December 2010, No. 4449's whistle, greatly worn from years of use with only one chime working properly, was replaced with an authentic SP Flat-Top Hancock 3-chime whistle from another Daylight Locomotive. This whistle remains on the locomotive to this day. Following a two-year hiatus needed to accommodate the locomotive's mandatory 15-year inspection and overhaul, SP 4449 returned to service on November 25, 2015. From 2016 to 2019, SP 4449 pulled several excursion trains during each year. In late 2019, the locomotive was scheduled to haul the annual 40-minute round-trip "Holiday Express" fundraiser trains through Portland's Oaks Bottom Wildlife Refuge, along the Willamette River, during November and December of that year. Due to its long rigid wheelbase and heavy weight, which were determined to cause excessive wear to the Oregon Pacific Railroad tracks being used, the engine no longer pulls the annual Oaks Park Holiday Express trains, and another locomotive was substituted in 2022 for the foreseeable future. As of 2022, 4449 is most commonly housed inside the Oregon Rail Heritage Center, only fired up on occasion. Preservation and maintenance 4449 is maintained by Doyle McCormack, a retired Union Pacific engineer and locomotive collector, along with many
