Question: Which board game was centered around the construction of a railroad track: Monopoly Junior, or TransAmerica? 
Context: Rich Uncle Pennybags is the mascot of the game "Monopoly".  He is depicted as a portly old man with a moustache who wears a morning suit and top hat.  (It is a common misconception that he is depicted with a monocle, but this is not the case.)  In large parts of the world he is known, additionally or exclusively, as the Monopoly Man, or Mr. Monopoly.  He also appears in the related games "Advance to Boardwalk", "Free Parking", "Don't Go to Jail", "Monopoly City", "Monopoly Junior", and "Monopoly Deal". TransAmerica is a railroad board game centered on the construction of railroad track in the United States.  The game was created by Franz-Benno Delonge and developed by Team Annaberg.  It is published in the United States by Rio Grande Games.  In 2003 it was a Mensa Select recipient. Empire Builder is a railroad board game centered on the construction of railroad track and delivery of goods.  It was designed by Bill Fawcett and Darwin Bromley and released in 1982 by Mayfair Games. The history of the board game "Monopoly" can be traced back to the early 20th century.  The earliest known version of "Monopoly", known as "The Landlord's Game", was designed by an American, Elizabeth Magie, and first patented in 1904 but existed as early as 1902.  Magie, a follower of Henry George, originally intended "The Landlord's Game" to illustrate the economic consequences of Ricardo's Law of Economic rent and the Georgist concepts of economic privilege and land value taxation.  A series of board games were developed from 1906 through the 1930s that involved the buying and selling of land and the development of that land.  By 1933, a board game had been created much like the version of "Monopoly" sold by Parker Brothers and its related companies through the rest of the 20th century, and into the 21st.  Several people, mostly in the Midwestern United States and near the East Coast, contributed to the game's design and evolution. Monopoly Star Wars is a 1997 video game based on the board game of the same name.  It is one of many video game adaptions of the board game Monopoly.  The game was developed by Artech Digital Entertainment and published by Hasbro Interactive.  It was released exclusively for Microsoft Windows.  The game employs the same basic ruleset of traditional Monopoly gameplay, but adds a "Star Wars" theme which includes famous characters and locales in place of the original game pieces and properties. Voestalpine Nortrak,Inc VAE Nortrak is a manufacturer of railroad track components.  It started in October 1981 as Nortrak Railway Supply Ltd., an industrial supplier of new and used railroad track components.  In November 1983, the company began manufacturing trackwork in Richmond, British Columbia, Canada.  In 1990, Voest-Alpine Eisenbahnsysteme of Austria, which had been in the trackwork manufacturing business for over 140 years and became independent of Voest-Alpine AG that same year, formed a joint venture with Nortrak Ltd. and the company became known as VAE Nortrak Ltd.  Voest-Alpine Eisenbahnsysteme became known as VAE Group, 90 percent owned by a joint venture between Voest-Alpine and Vossloh AG starting in 1998, and a subsidiary of voestalpine AG since 2003. A traquero is a railroad track worker, or "section hand", especially a Mexican or Mexican American railroad track worker ("gandy dancer" in American English usage).  The word derives from "traque", Spanglish for "track". Savage's Station was the wartime name of a supply depot, ammunition dump, field hospital, and command headquarters of the Army of the Potomac during the Peninsula Campaign of the American Civil War.  Savage's Station was located in Henrico County, Virginia on what was the Richmond and York River Railroad, however the historical department of the Norfolk Southern Railroad, the railroad track's current owner, has no record that an actual train station or station house ever existed on the property.  A farmhouse is known to have been located in a copse of trees on a small knoll next to the railroad track and is visible in several period drawings and photographs made during the war.  The house served as the nucleus of a large field hospital during and after the battle of Seven Pines and the Seven Days Battles.  The house also functioned as General George B. McClellan's headquarters during the battle of Savage's Station on June 29, 1862.  Although the house survived the battle in 1862, it was burned by Federal cavalry under General Philip H. Sheridan in 1864.  The house appears to have never been rebuilt, and no trace of it remains today.  However, a smokehouse from the 19th century still existed on the property as late as the 1930s when it was photographed during a survey of local historical structures as a project of the Civilian Conservation Corps.  The smokehouse fell into ruin and collapsed sometime prior to the 1980s.  A small brick-walled cemetery from the 18th century still sits near the former location of the house not far from the railroad track. Tracks to Telluride is a railroad board game centered on the construction of railroad track, and servicing mines along those railroad tracks.  The setting of the game is in southwestern Colorado during the mining boom of 1873 through 1888.  The game was developed by John Bohrer with playtesting by the Edgewood Gaming Group and the Pittsburgh Smoking Engineers. Monopoly Junior is a simplified version of the board game Monopoly, designed for young children.  It has a rectangular board that is smaller than the standard game and rather than using street names it is based on a city's amusements (a zoo, a video game arcade, a pizzeria, etc.) to make the game more child-friendly.
