The streamlined design of 13N was replaced by a more boxy shape which made for excellent visibility - unfortunately in daytime only.

The large windscreen was tilted is such a way that at night-time it reflected light directly into the driver's eyes making the 102N difficult to drive after dark.

This issue was ultimately to prove the downfall of the 102N, as after producing just 42 units the company decided to abandon the 102N project, and in 1970 reverted to the 13N look for the newer 102Na model.

Konstal 802N was a version of 102N adapted to use on 1000 mm tracks, but only five units were built before the company decided to switch the production to a newer 803N model.

Konstal 102N was delivered to Kraków, Poznań, Wrocław, Gdańsk and the Silesian network, but due to visibility issues most of them were quickly withdrawn from service.
