The GTL8 (Gelede Tram Lang / Articulated Tram Long, with 8 powered axles) was first introduced in 1981 (147 units were build between 1981 and 1993, in two series; 3001-3100 and 3101-3147), and the last ones are still in service on a few lines in The Hague, due to be replaced in 2026 (new TINA trams have been ordered).
The Amsterdam 11G and 12G trams were based on this design.

I am currently working on the first step; producing the parts in Sketchup, now working on creating the interior.
