Trams of this type are used in Cottbus, in Brandenburg an der Havel and on the Schöneiche-Rüdersdorf Tramway in Germany, and in Tallinn, Estonia, where they are called '''KT6TM'''. A similar variant of KT4 is the '''KTNF8''', which is used in Gera, Germany.<ref>{{cite web |url=http://www.skd.cz/EN/tramvaje/KTNF8.htm |title=The KTNF8 (KT4NF) Tram Unit |website=skd.cz |archive-url=https://web.archive.org/web/20150924102319/http://www.skd.cz/EN/tramvaje/KTNF8.htm |archive-date=24 September 2015}}</ref>
