Line no. 26 was only a streetcar line from April the 3rd 1944 to Novenber the 5th 1945.

The reason why the line was established, was to reduce the use of rubber at the trolley-line 26, so a part of the trolley-line was, instead of the bus, trafficked by an electric streetcar.

The Company running the line was NESA, which is a power supplier. NESA was running the northern parts of line no. 14 and line no. 15 until 1953.

The last day for the line to be a streetcar line was Novenber the 5th 1945, where it again became a trolley-line.
