43A  (Łódź) – Łódzka – Jana Pawła II – Plac Wolności The Łódź–Konstantynów Łódzki line was opened in 1911.

It was built and operated by Łódzkie Wąskotorowe Elektryczne Koleje Dojazdowe (Łódź Narrow-gauge Electric Commuter Railways).

The line was technically compatible with the Łódź trams network (same gauge and electrification system), allowing interrunning, but the two were not connected, passengers had to change at interchange stops located near the city limits.

[1] In the early 1970s, the last dedicated suburban rolling stock was withdrawn from service, since when the line was worked by the tramcars also used on the city network.

[3] The revitalisation of the section from Łódź to Plac Wolności (the Konstantynów terminus) was scheduled to start in 2022 and trams are due to return by the end of 2023.
