This is a route-map template for the Porto Metro, a light rapid transit system in Portugal.

• For a key to symbols, see {{railway line legend}}.
• For information on using this template, see Template:Routemap.
• For pictograms used, see Commons:BSicon/Catalogue.

Note: Per consensus and convention, most route-map templates are used in a single article in order to separate their complex and fragile syntax from normal article wikitext. See these discussions ^[i],[ii] for more information.
