today I want to present / discuss / ask for editing the different tramway models referred to as "GTxN/M/S". https://de.wikipedia.org/wiki/GTxN/M/S
That stands for "Gelenk-Triebwagen mit x Achsen für Normalspur/Meterspur/Schmalspur" (Articulated railcar with x axles for standard gauge [1435 mm] / meter gauge / narrow gauge)
Back in 1989 the worlds first 100% low floor called GT6N [Articulated railcar with 6 axles for standard gauge] tram was presented in Bremen:
It has been built by MAN Gutehoffnungshütte Schienenverkehrstechnik AG (MAN GHH) which has been transferred from Maschinenfabrik Augsburg Nürnberg AG (MAN) in 1986. https://de.wikipedia.org/wiki/MAN#MAN_S ... hrstechnik.
MAN GHH was sold to AEG in 1990 and renamed to AEG Schienenfahrzeuge Nahverkehr & Wagen GmbH (AEG) on 01.07.1993.
Meanwhile, another four prototypes were built: 3 GT6N for München [Munich] in 1990/91 and 1 GT6M [meter gauge] for Augsburg in 1992.
In Munich these cars were classified as R1.1.
So far we have 4 MAN GHH GT6N and 1 MAN GHH GT6M.
In May 1993, the first of twelve GT6M for Zwickau has been delivered. The other 11 cars were delivered after 01.07.1993.
discussion point: Strictly speaking Zwickau received 1 MAN GHH GT6M and 11 AEG GT6M.
Technically, it is one series, and even before the renaming into AEG Schienenfahrzeuge Nahverkehr & Wagen GmbH already belonged to AEG.
So Zwickau should have received 12 AEG GT6M.
With that in mind, the prototypes for Munich and Augsburg are AEG GT6N and AEG GT6M as well!
In July 1993, the 78 piece AEG GT8N series delivery for Bremen began.
In 1994/95 Frankfurt (Oder) received 8 AEG GT6M
In 1994 the AEG GT6N series delivery for Berlin and Munich began. In Munich these cars were classified as R2.2.
In 1995 Braunschweig received 12 AEG GT6S.
In 1995 the AEG GT6N series delivery for Nürnberg [Nuremberg] began.
In December 1995 the first of ten GT6M-ZR for Jena has been delivered. The other 9 cars were delivered in 1996.
On January 1, 1996, the merger of ABB (AEG) and Daimler-Benz was carried out, commonly known under its brand Adtranz. https://en.wikipedia.org/wiki/Adtranz
In 1996 Augsburg received 11 ADtranz GT6M
In 1996 Mainz received 16 ADtranz GT6M-ZR and the GT6M-ZR series delivery for Jena continued as ADtranz GT6M-ZR.
The GT8N series delivery for Bremen continued as ADtranz GT8N.
The GT6N series delivery for Berlin, Munich and Nuremberg continued as ADtranz GT6N.
Between 1998 and 2000 Nuremberg received 26 ADtranz GT8N2.
In 1999 the ADtranz GT8N2 series delivery for Munich began. In Munich these cars were classified as R3.3.
In 1999 the ADtranz GT6N-ZR series delivery for Berlin began.
On May 1, 2001, the takeover of Adtranz by Bombardier came into legal effect. https://en.wikipedia.org/wiki/Adtranz & https://en.wikipedia.org/wiki/Bombardier_Transportation
The GT6N-ZR series delivery for Berlin continued as Bombardier GT6N-ZR.
In 2002/03 Jena received 14 Bombardier GT6M-ZR
