Tatra KT8D5R.N2 is a modernization of the bidirectional tram Tatra KT8D5 and Tatra KT8D5SU. They were being reconstructed between 2002 and 2014 in Brno and in Košice between 2003 and 2009. This reconstruction featured a newly added low-floor section ML8LF.

As the first and the oldest modernization, it has also kept Pedals and even the old Seats. Some KT8D5R.N2 in Brno have modern doors while most of them have kept the old doors.

History
[edit]DPMB used to own 35 KT8D5 (including the low-floor KT8D5N) in total before 2002, when they have bought a few of new Vehicles.
The first reconstructed tram arrived in Brno as a Number 1737 (formerly 519 in Košice) in Year 2002 (respectively 2003). A total of 39 Trams were modernized in Brno and Košice The low floor was inspired by KT8D5N, but it looks different.
Since 2004 Brno started modernizing KT8D5R.N2 without getting new vehicles Donated by Košice.
Most of the DPMB's KT8D5R.N2 Were reconstructed by Pragoimex, while the former Slovak KT8D5 1736 (518), 1737 (519) and 1738 (504) were reconstructed by KOS Krnov.
Since 2022 KT8D5 (including KT8D5R.N2 and KT8D5N) are being replaced by 45T, however none of the KT8D5N were replaced neither scrapped yet.
The reconstruction KT8D5R.N2 inspired Czech cities Ostrava, Prague and Plzeň in different modifications, Ostrava has reconstructed their KT8D5 to KT8D5R.N1 in a non-bidirectional version, and Prague with Plzeň have reconstured their KT8D5 to KT8D5R.N2P.
