Question: The Alaska Railroad passes through which US Army Post?

Context paragraphs:
Alaska Railroad: The Alaska Railroad (reporting mark ARR) is a Class II railroad which extends from Seward and Whittier, in the south of the state of Alaska, in the United States, to Fairbanks (passing through Anchorage), and beyond to Eielson Air Force Base and Fort Wainwright in the interior of that state.  Uniquely (for the US), it carries both freight and passengers throughout its system, including Denali National Park.  The railroad has a mainline over 470 mi long and is well over 500 mi including branch lines and siding tracks.  It is currently owned by the state of Alaska.  The railroad is connected to the contiguous 48 via three rail barges that sail between the Port of Whittier, Alaska and Harbor Island in Seattle (the Alaska Railroad-owned Alaska Rail Marine, from Whittier to Seattle, and the CN Rail-owned Aqua Train, from Whittier to Prince Rupert, British Columbia) but does not currently have a direct, land-based connection with any other railroad lines on the North American network.  In 2016, the company suffered a net loss of $4.3 million on revenues of $169.8 million, holding $1.1 billion in total assets.

James Wickersham: James Wickersham (August 24, 1857 – October 24, 1939) was a district judge for Alaska, appointed by U.S. President William McKinley to the Third Judicial District in 1900.  He resigned his post in 1908 and was subsequently elected as Alaska's delegate to Congress, serving until 1917 and then being re-elected in 1930.  He was instrumental in the passage of the Organic Act of 1912, which granted Alaska territorial status, introduced the Alaska Railroad Bill, legislation to establish McKinley Park, and the first Alaska Statehood Bill in 1916.  He was among those responsible for the creation of the Alaska Agricultural College and School of Mines, which later became the University of Alaska.  A residence hall on the University of Alaska Fairbanks campus is named in his honor.

Bootleggers Cove, Anchorage: Bootleggers Cove (alternately called "Bootlegger Cove", "Bootleggers' Cove", and "Bootlegger's Cove") is an area of Anchorage, Alaska, just west of Downtown Anchorage and north of the South Addition.  Its exact boundaries are controversial.  It is served by Inlet View Elementary School, Romig Junior High and West Anchorage High School.  Its scenic features include Elderberry Park, the Oscar Anderson House, the Westchester Lagoon, and access to the Tony Knowles Coastal Trail and the Lainie Fleischer Bike Trail.  It is located near the tidal flats of Cook Inlet.  The Alaska Railroad passes between the residential zones of Bootleggers Cove and the tidal flats.  Bootlegger's Cove was affected by the 1964 Alaska earthquake.  It is currently represented in the Alaska State Legislature by Representative Les Gara and Senator Johnny Ellis.

Anchorage Depot: Anchorage Depot, also known as Alaska Railroad Depot, is the railroad station at the center of the Alaska Railroad system at the junction of the two main lines their trains run on.  It serves as the starting point for many tourists traveling on the luxury trains such as the Denali Star.  The station is a Moderne-style three story concrete building, built in 1942 and enlarged in 1948.

Harding Railroad Car: The Harding Railroad Car is a historically significant Pullman railroad passenger car located at Pioneer Park (aka Alaskaland) in Fairbanks, Alaska.  Also called Denali, and designated with equipment number X-336 by the Alaska Railroad, the car was one of three used to carry a delegation that included President Warren G. Harding in 1923 to the ceremony marking completion of the railroad between Fairbanks and Seward.  The car was purchased by the Alaska Railroad in 1923 from the Great Northern Railroad, and was used in its service until 1945.  At the urging of the Fairbanks chapter ("igloo") of the Pioneers of Alaska, the car was restored in 1959–60 and given to the city of Fairbanks.  It was placed in Alaskaland in 1967, created to mark the centennial of the Alaska Purchase.  It was used for some years as the park's visitor center.

Fort Raymond (Alaska): Fort Raymond was a U.S. Army Post established in Seward, Alaska in 1942.  The fort was named for Charles W. Raymond, who had served as a captain in the U.S. Army Corps of Engineers.  At one point the garrison included more than 3,000 officers and men.  The post was established to protect the dock and railroad facilities in Seward and included a garrison and coastal and anti aircraft artillery.  These transportation facilities were critical to the buildup of military facilities throughout Alaska.  Supplies and materials arriving by ship to Seward were transported to Anchorage and Interior Alaska via the Alaska Railroad.

Alaskan Engineering Commission: The Alaskan Engineering Commission (AEC) was a U.S. Federal agency, sometimes known by its initials or by alternate spelling Alaska Engineering Commission.  It was created by the Alaska Railroad Act in 1914, by U.S. President Woodrow Wilson, in order to arrange for construction of a railway system in Alaska.  William C. Edes was named chairman, chief engineer Colonel Frederick Mears.  In 1915, the AEC became part of the U.S. Department of the Interior.  In 1923, after the railroad began operation and construction was complete, it became the Alaska Railroad Commission, later renamed to The Alaska Railroad.
