The Warsaw Metro is a rapid transit underground system serving the Polish capital Warsaw. It currently consists of two lines, the north–south Line M1 which links central Warsaw with its densely populated northern and southern districts, and the east–west Line M2. Three more lines are still being planned. The system is operated by Metro Warszawskie sp. z o.o., a company owned by the city, and managed by Zarząd Transportu Miejskiego w Warszawie. As of 2024 it is the only metro system in Poland.
