context_page_description: Commuter rail, or suburban rail, is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Generally commuter rail systems are considered heavy rail, using electrified or diesel trains. Distance charges or zone pricing may be used.
  The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail.
  Similar non-English terms include Treno suburbano in Italian, Cercanías in Spanish, Rodalies in Catalan, Proastiakos in Greek, Train de banlieue in French, Příměstský vlak or Esko in Czech, Elektrichka in Russian, Pociąg podmiejski in Polish and Pendeltåg in Swedish.
  Some services share similarities with both commuter rail and high-frequency rapid transit, examples being the German S-Bahn, the Réseau Express Régional in Paris, many Japanese commuter systems, and some Australasian suburban networks. Some services, like British commuter rail, share tracks with other passenger services and freight.
context_section_description: Examples include an 899 km (559 mi) commuter system in the Buenos Aires metropolitan area, the 225 km (140 mi) long Supervia in Rio de Janeiro, the Metrotrén in Santiago, Chile, and the Valparaíso Metro in Valparaíso, Chile. Another example is Companhia Paulista de Trens Metropolitanos (CPTM) in Greater São Paulo, Brazil. CPTM has 94 stations with seven lines, numbered starting on 7 (the lines 1 to 6 and the line 15 belong to the São Paulo Metro), with a total length of 273 kilometres (170 mi).
