41  (Łódź) – (Ksawerów) – Warszawska – Stary Rynek – Zamkowa – Łaska – Wiejska The Łódź–Pabianice line was opened in early 1901.

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[1] In the early 1970s the last suburban motor coaches were withdrawn from service, since then the line was worked by the tramcars also used on the city network.

[3] The condition of the line became progressively worse to the point that it was necessary to suspend the running of trams and perform a complete rebuild of it.
