From Wikipedia, the free encyclopedia

[edit] Construction
105N is a single module, one-way engine car with four doors on the right side.
The design came about as a result of the modernisation of Konstal's earlier 13N model from the 1960s and 1970s. All the electrical systems from the old model remained, but the new model abandoned the box-like appearance of its predecessor for a more angular look. The side windows were enlarged, and smaller windows were added on the front and sides, leading to its being nicknamed the aquarium. The first models lacked the ability to be connected to one another, and the placement of the electrical system caused problems with humidity. The tram was equipped with electromagnetic, drum and rail brakes. Its chief engineers were Zygmunt Giziński and Wojciech Kozik.
The upgraded version of the 105N is the Konstal 105Na.
[edit] Versions
The basic version, 105N (and later series of 105N/1 with only minor changes), had 980 units.
In 1977 4 105NW cabs for Bydgoszcz and Łódź, were made for narrow-gauge tracks.
25 units of a new version for Łódź, the 805N were built in 1978.
In 1995, on a base of two 105N cabs, HCP in Poznań built a prototype of a three-module, partially low-floor tram, the Konstal/HCP 105N/2 - the first of its kind built in Poland.
[edit] Usage
105N trams were used in all Polish cities with tram systems. During their years of service, most of them were modernised and upgraded to the 105Na variant, so today there are only a few of them remaining. In Gdańsk (1), Poznań (2), and Szczecin (2) there are cabs rebuilt to the earliest version.
105NW, the narrow-gauge version was used in Bydgoszcz and Łódź, but the cabs were upgraded. 805N cabs in Łódź were also upgraded to 805Na.
