In 2019, Škoda Transportation, a company based in Plzeň, Czech Republic, was awarded with a contract worth 1,308 billion Polish złoty for 37 trainsets, each with six cars.

The 222 cars—including 74 driver and 148 passenger cars—were to be delivered to the Warsaw Metro, where they would be used on the extended M2 route and also ultimately replace the old Metrovagonmash cars on the M1 line.

The aluminum cabins were welded and varnished in the Škoda Vagonka factory in Ostrava, Czech Republic, and the final assembly and testing took place in Plzeň.

The contract also included the preparation of a simulator training programme, as well as an extended warranty and spare parts.

In the following nights, more driving tests were conducted, and the length of the route was extended to the city centre.
