The rail line on which the steam locomotives in Greenfield Village presently run originally consisted of a simple straight stretch of track along the northern edge of the museum property, and has been present ever since Greenfield Village was dedicated in 1929. The rail line, now named the Weiser Railroad, was later expanded into a continuous loop around the perimeter of the museum property, which was completed in stages between 1971 and 1972. This passenger line is long and has four stations. All of the railroad's stations consist solely of single side platforms except for the station in the Railroad Junction section, which also includes the relocated Smiths Creek Depot building originally built for the Grand Trunk Railway in 1858.
