The term Spanish Solution refers to a transit station design principle whereupon platforms are located on both sides of a track. This is used at high-volume stations to make it easier for patrons to board and alight. Sometimes one platform is reserved for boarding and the other for alighting, in other instances either platform can be used for either purpose. Examples include Atlanta's Five Points station, Munich's Marienplatz (S-bahn), and Charles de Gaulle - Etoile on Line 6 in Paris. It takes its name from early implementation on Barcelona's Metro, although the earliest instance occurred at Park Street Under (Red Line) in Boston in 1912.
