The Konstal 105Na are a class of Polish trams manufactured from 1979 to 1992 in workshops Konstal Chorzow, Poland. The narrow-gauge version is designed as 805Na. As of 2016 they are still the most common trams in Poland.

Construction

105Na is unidirectional motor tramcar, equipped with four doors.

It represents the development of the earlier tram Konstal 105N, the main changes being the location of the components of the electrical equipment which were transferred from under the steps to the back wall of the driver's cabin, the introduction of a separate cabin for the driver and the removal of the small windows under the front and side windscreens. The most important change was the introduction of motor grouping, which reduced the energy consumption by 12%. During initial acceleration, the four motors are connected in series, whilst at higher speeds, two groups of motors are connected in parallel.

While in service, the 105Na vehicles were the subject of various modifications and upgrades (including changes in the electrical system, new front plastic, change of the door opening mechanism, and even re-design, for Poznań, to the bidirectional Konstal 105NaDK). Almost all 105N cars in Poland have over time been modernised to the 105Na standard.

Other variants

The Konstal 105Na and 805Na trams provided the basis for the production of a large number of prototypes and variants:


Production numbers

The number of standard-gauge version 105Na vehicles produced is 1443 while the number narrow-gauge version, the 805Na, is 691.
