Question: Which is a drink named celebrating a train which ran between New York City and Chicago: Sundowner or 20th Century?
Context: The 20th Century Limited was an express passenger train on the New York Central Railroad (NYC) from 1902 to 1967, advertised as "The Most Famous Train in the World".  In the year of its last run, "The New York Times" said that it "...was known to railroad buffs for 65 years as the world's greatest train".  The train traveled between Grand Central Terminal (GCT) in New York City and LaSalle Street Station in Chicago, Illinois, along the railroad's "Water Level Route". The architectural firm of Starrett & van Vleck, often spelled Starrett & Van Vleck, specialized in the design of early 20th century department stores primarily in New York City.  The partner Goldwin Starrett, brother of Colonel William A. Starrett, had worked for four years in the Chicago office of Daniel Burnham.  Included in their designs were the New York City flagship stores of Lord & Taylor, Bloomingdales, Saks Fifth Avenue, Abraham & Straus, and Alexander's.  The Lord and Taylor store, located on Fifth Avenue between 38th and 39th streets, was completed in 1914 and was Starrett & van Vleck’s first major department store.  In December 2007, the store was named a New York City landmark. The 400 (later named the Twin Cities 400) was a named passenger train operated by the Chicago and North Western Railway between Chicago and Saint Paul, with a final stop in Minneapolis.  The train took its name from the schedule of 400 miles between the cities in 400 minutes, and was also a nod to "The Four Hundred Club", a term coined by Ward McAllister to refer to the social elite of New York City in the late 19th century.  It was an express train with limited stops between Chicago and the Twin Cities.  It ran from 1935 to 1963 and spawned a number of ""400"" trains. Transportation in New York City has ranged from strong Dutch authority in the 17th century, expansionism during the industrial era in the 19th century and half of the 20th century, to cronyism during the Robert Moses era.  The shape of New York City's transportation system changed as the city did, and the result is an expansive modern-day system of industrial-era infrastructure.  New York City, being the most populous city in the United States, has a transportation system which includes one of the largest subway systems in the world; the world's first mechanically ventilated vehicular tunnel; and an aerial tramway. The 20th Century is a cocktail created in 1937 by a British bartender named C.A. Tuck, and named in honor of the celebrated "Twentieth Century Limited" train which ran between New York City and Chicago from 1902 until 1967.  The recipe was first published in 1937 in the "Café Royal Cocktail Book" by William J Tarling, President of the United Kingdom Bartenders' Guild and head bartender at the Café Royal. Rollie Hubert Zeider (November 16, 1883 – September 12, 1967) was a professional baseball player.  An infielder (playing over 100 games at all four infield positions in his career), he played nine seasons in Major League Baseball for the Chicago White Sox (1910–13), New York Yankees (1913), Chicago Chi-Feds/Chicago Whales in the Federal League from 1914–15, and lastly the Chicago Cubs (1916–18).  He is one of only a few players to play for three different Chicago teams in his career, and one of two to do it in the 20th century.  He is the only player to hit home runs for all three Chicago major league teams in the twentieth century.  Along with Dutch Zwilling he is the only 20th century player to play in the same city in three different major leagues: American League (White Sox), Federal League (Chi-Feds/Whales), and the National League (Cubs). The New York Central Hudsons were a series of 4-6-4 "Hudson" type steam locomotives built by the American Locomotive Company and the Lima Locomotive Works from 1927 to 1938 for the New York Central Railroad.  Named after the Hudson River, the 4-6-4 wheel arrangement came to be known as the "Hudson" type in the United States as these locomotives were the first examples built and used in North America.  Built for high-speed passenger train work, the Hudson locomotives were famously known for hauling the New York Central's crack passenger trains, such as the "20th Century Limited" and the "Empire State Express".  With the onset of diesel locomotives in the mid 20th Century, all Hudson locomotives were retired, with none preserved. In the United States there are large concentrations of Italians in many metropolitan areas of the United States.  The most comprehensive look at all of these neighborhoods can be seen at the Italian Enclaves Facebook page.  In particular, states such as New York, Rhode Island, Connecticut, Michigan, Florida, California, Illinois, New Jersey, Ohio, Pennsylvania, and Massachusetts have larger populations of Italian-Americans than other states by national average.  According to a recent United Census Bureau estimate, 17.8 million Americans are of Italian descent.  Communities of Italian Americans were established in most major industrial cities of the early 20th century, such as Baltimore, Boston (particularly in the "North End"), Philadelphia (particularly in certain neighborhoods of South Philadelphia), Pittsburgh, Detroit, Providence, St. Louis, Chicago, Kansas City, Milwaukee, Youngstown, Erie, Cleveland, Buffalo, and New York City, which boasts the largest Italian-American population, which live in several concentrated communities in the New York Metropolitan Area.  New Orleans, Louisiana was the first site of immigration of Italians into America in the 19th century, before Italy was a unified nation-state.  This was before New York Harbor and Baltimore became the preferred destinations for Italian immigrants. A sundowner, in colloquial British English, is an alcoholic drink taken after completing the day's work, usually at sundown. The Broadway Limited was a passenger train operated by the Pennsylvania Railroad between New York City and Chicago.  It operated from 1912 to 1995.  It was the Pennsylvania's premier train, competing directly with the New York Central Railroad's "20th Century Limited".  The "Broadway Limited" continued operating after the Penn Central Transportation merger, one of the few long-distance trains to do so.  Penn Central conveyed the train to Amtrak in 1971; Amtrak discontinued it in 1995.  The train's name referred not to Broadway in Manhattan, but rather to the "broad way" of the Pennsylvania's four-track right of way along a large portion of the route.
