The TW 6000 is a type of articulated light rail vehicle used on the Hanover Stadtbahn system, manufactured by Duewag, Linke-Hofmann-Busch, AEG, Kiepe and Siemens.

The vehicle can serve both high platforms and street-level stops; it has cabs at both ends, thus eliminating the need for turning loops.

It was unique in Germany at the time for featuring thyristor chopper control and a contemporary design by Herbert Lindinger.

The following TW 6000 series were delivered: The lead of the consortium changed over to LHB after the first series due to political lobbying, as subsidies provided by the state of Lower Saxony were spent on the project, LHB (which is based in Salzgitter) was favoured over the out-of-state Duewag (with their operations in Düsseldorf, North Rhine-Westphalia).

All TW6000s are driven using an integral traction and braking system with a deadman's trigger that drivers must depress to mobilize the vehicle.

Nowadays, the main concern about these cars is their high floor level and moving stairs with mechanical sensors that do not fulfill accessibility requirements and make it difficult for the elderly, and people with prams, to get on and off.

Despite this, its heated passenger compartment, good noise insulation, vibration damping and seamless acceleration mean a higher standard of comfort than some other tram types in Budapest can provide.

In October 2024 BKV has started to officially explore the idea of running TW6000 trains on some HÉV lines, replacing the outdated and ageing rolling stock.
