M1 (Warsaw)

The M1 line is the first line of the Warsaw Metro. It is 23.1 km long, has 21 stations and runs from the Kabaty neighborhood in the Ursynów district to the Młociny district in Bielany.

The decision to build it was made in 1982, and a year later the first works in Ursynów began. In 1995, the first section of the route connecting Ursynów and Mokotów with Śródmieście was launched, and the next sections were put into operation in the following years. In 2008, construction of the Bielany section was completed and crossings on the whole line were started. There is also a plan to add two additional stations around the center portion of the metro line.

M1 trains run from approximately 5:00 AM to 12:10 AM (from Monday to Thursday and Sunday) and from approximately 5:00 AM to 3:00 AM (Fridays and Saturdays).

Rolling stock
The line used to be operated by 81-series trains. These sets were retired in 2023. One 6-car set (Number 02) was kept as a heritage unit.

Depots
A single depot, STP Kabaty, is located south of the Kabaty station. This depot is used, among others, for repairing, maintaining, and testing metro trains. As of 2020, the depot itself employed around 500 people.
