The backbone of the streetcar system in Wroclaw are still the Konstal 105N cars. They can not hide their relationship with PCC cars. The Polish manufacturer Konstal copied many PCC features, even if he was not licensed as the CKD Tatra of Prague was.
In Wroclaw, they ride in two-car trains, with the second car mostly "downgraded" as a motor trailer without controls.
A number of the Konstal 105N were rebuilt and recieved new doors and new front and rear ends made of plastic with rectangular headlights.
