The TW 3000 (manufacturer designation GTZ6-H ) is a light rail vehicle for the Hanover light rail system , which was produced by a consortium of three companies between 2013 and 2020 . The TW 3000 is the successor to the TW 2000 procured from 1997 to 2000 . In the medium term, it is intended to replace some of the TW 6000 multiple units acquired between 1974 and 1993 .

description

The dimensions of the wagons of the TW 3000 series are roughly the same as those of the TW 2000 series, they are 2.65 m wide and 25 m long. They have three bogies and four double swivel and slide doors on each side of the car . Thanks to efficient energy recovery, the 39.8-tonne trams have around 15 percent lower energy requirements than their predecessor. The four motors each have an output of 125 kW. As with the TW 2000, there are screens for passenger television . A colored lighting concept enables three different types of lighting: a warming yellow color for cool days, a cool blue for warm days and a calming green for event traffic.

Like the other vehicles of the Hannover Stadtbahn, the TW 3000 series cars are high-floor vehicles with a level car floor without annoying wheel arches, steps and ramps. In contrast to the TW 6000 and TW 2000 series, the TW 3000 series wagons do not have any folding steps , which reduces acquisition and maintenance costs. They can therefore only be used on routes that are fully equipped with elevated platforms.

The bogies lead to lower noise emissions because of the rubber-sprung wheels with wheel sound absorbers and soundproof boxes.

50 vehicles of the series will be retrofitted with a collision warning system based on camera and radar with warning and brake intervention functions by 2020 .

purchase

In a Europe-wide invitation to tender, three manufacturers submitted offers. The Üstra opted for a consortium of vendors Transport Germany Alstom (chassis and wheels) and Vossloh Kiepe (electrical equipment). The Heiterblick GmbH in Leipzig provides the car bodies and takes care of the assembly of the components. HeiterBlick does not build the car bodies itself, but has them made by subcontracting them. Since the manufacturer Bombardier had called the tendering chamber about the result of the tender, the last round of the tendering process had to be repeated. Then the consortium was again awarded the contract. The delivery originally planned for 2012 was delayed by a year. The first vehicle was delivered on November 15, 2013, and service in scheduled service was originally scheduled to begin in early 2014.

In a first tranche starting in 2013, 50 vehicles were initially ordered for 126 million euros, with the state of Lower Saxony contributing half of the costs through the regional transport company (LNVG). In November 2012, when a revised model was presented before production began, Üstra announced that it had applied for funding from the state for the purchase of a second series of 50 units. Since there are no development costs for this series, the acquisition costs should be over 10 million euros below those of the first series. On the occasion of the delivery of the first vehicle, Üstra announced that the order had been placed for the second series, which should be built by 2018. There was an option for a further 46 vehicles. On June 1, 2017, Üstra redeemed the second option for a third delivery lot for 46 TW 3000. By the end of 2019, all 146 cars originally planned for this series should be delivered. Üstra was able to finance four additional wagons from a reimbursement that it should receive from the manufacturer consortium due to quality defects. In March 2018, Üstra announced the order for a further seven vehicles.

The TW 3000 was presented on March 7, 2014 at the Glocksee depot; commissioning was scheduled for mid-March 2014. However, due to faulty welds, the TW 3000 could not be used for the time being. Samples from Üstra revealed serious defects in 55% of the vehicles. Because of these problems, HeiterBlick changed the manufacturer of the car bodies. After a company from Salzgitter first manufactured the car bodies, this was then taken over by a company from Dessau. The vehicles 3001 to 3018 were repaired by the manufacturer in a workshop of Üstra in Hanover during 2015.

With the TW3000, in contrast to the previous models, Üstra increasingly relied on various partnerships in the form of public participation in order to identify and meet quality requirements in advance. Basically every citizen could apply for test sessions, but this completely ignored the properties that the seats had to have when driving, especially when accelerating and braking. After the introduction, this led to massive criticism of the built-in seats, as they had practically no anti-slip properties. A rework was rejected by Üstra in 2016 as not feasible. One tries to avoid such bad planning in future models.

The procurement program for a total of 146 vehicles, which was originally extended to the mid-2020s, was intended to enable the network to be adapted and the TW 6000 series wagons to be gradually decommissioned and the financial requirements to be spread over a longer period of time. However, due to the increasing demand for vehicles for longer trains and repeater journeys, the vehicle fleet is now being enlarged, so the new vehicles will not be able to completely replace the TW 6000, as originally planned. Due to the upcoming route extensions and longer trains on other lines, it can be assumed that the fleet will be further enlarged. In August 2016 the fleet already comprised 302 light rail vehicles. In March 2018 there were 323 and in November 2018 330 cars.

The 100th car was delivered in early October 2018. It has been used in scheduled services since mid-November 2018.

The 153rd and last wagon was delivered to Üstra on July 2, 2020 and used for the first time in regular service on July 30, 2020.

Further development

The vehicles of the second series from number 3051 on have a few differences to the first series. The display of the course number has been moved from the driver's cab side window to the windshield. The floor covering in the area of ​​the seats is anthracite instead of beige. The seats now do without the characteristic green edge all around. All individual seats (in the four corners of each car head) are now wider than before. Some cars have short backrests behind the single folding seats. The vehicles from number 3061 are provided with the new Üstra word and image brand, the previous vehicles still carried those from the 1990s such as the TW 2000.

Problems

In the TW-3000, narrow and slippery seats are criticized (despite improvements). In addition, a very loud driving noise with poor suspension and much too bright lighting. This is the first vehicle that passengers actively avoid.

From serial number 3050 onwards, the seats have been roughened to provide better support, but the seats are so poor that passengers prefer to stand.

The first use in scheduled operation took place on March 15, 2015 on Line 7. As a prerequisite for the scheduled use, all stops on the routes must be equipped with elevated platforms and the sweeping systems used with auxiliary platforms. So far, the routes on lines 3, 4, 5, 7 and 8 have been fully equipped with elevated platforms. In addition, the use of the TW 3000, just like the use of the TW 2000, requires a continuous expansion for 2.65 m wide vehicles.

Since the summer of 2015, individual TW 3000 trains have been used on Line 3. The first three-car trains have been on Line 7 since December 2015. Since then, Line 7 has mostly run exclusively with TW 3000.

In September 2016 it became known that the elevated platform stop Oldenburger Allee could not be operated with the TW 3000 due to renovation work and that it will be replaced by provisional underground platforms for an expected three months. Since the wagons of the TW 3000 series cannot serve underground platforms, they could not be used on Line 3 at this time. There are other elevated platforms that need renovation, mostly along the A and B routes.

Since the timetable change on December 12, 2016, the TW 3000 has been deployed on Line 4. In March 2017, the TW 3000 drove for the first time on Line 18, and in June 2017 on Line 16.

Since October 2017, the track spacing for 2.65 m wide cars has been continuously established on the line 5, but at the same time renovation of the Tiergarten elevated platform began, so that there was no elevated platform available here until the timetable change in December 2017. After the completion of the construction work, the TW 3000 has been running on Line 5 for the first time since March 9, 2018. At the 2018 timetable change, individual routes on Line 5 ran for the first time in the morning as a 3-car TW 3000 train.

Since the beginning of 2019, the TW 3000 has also been used again on Line 3, while Lines 4, 5 and 7 are mostly operated with TW 3000. There are now more TW 3000 than TW 6000, a good third of the vehicle fleet is TW 3000.

Since the Humboldtstrasse stop could not be operated from August to December 15, 2019 due to construction work, the TW 3000 could also be used on line 17. The missions on line 17 have so far been rare.

On November 30, 2019, the "Free Driving Day", there were operations on an amplifier line from Peiner Strasse to Dragonerstrasse.

The TW 3000 has been used on lines 2 and 8 since December 15, 2019, but on the former only on courses to Laatzen / Ginsterweg, as the stops Rethen, Rethen / Nord and Rethen / Steinfeld only have underground platforms.

Since January 2020, a 4 TW 3000 wagon train has been running on Line 8 for the first time.

The TW 3000 is back on line 17 since the Humboldtstrasse stop was closed again on May 11, 2020. The stop is only to be reopened when the elevated platform is completed.

The next two lines are to be expanded for the use of TW 3000.

  • Line 11: In 2019, preparatory work for an elevated platform began at the Hannover Congress Center. When the elevated platform is ready, all stops on line 11 will be expanded for the use of TW 3000. Completion is planned for 2020. The construction work was paused on April 14, 2020, as an evacuation measure would be difficult due to the COVID-19 pandemic and the existing restrictions if a World War II bomb was found.
  • Line 2: The section from Alte Heide to the intermediate end point Laatzen / Ginsterweg is already fully equipped with elevated platforms. On the southernmost section, elevated platforms are still missing at the Rethen / Steinfeld, Rethen / Nord and Rethen stops. The route is to be made barrier-free in this area and line 2 to Gleidingen / Orpheusweg is to be extended. The stops Rethen and Rethen / Nord are to be combined into one barrier-free stop Rethen / Pattenser Straße. After installing a track change behind the Laatzen / Ginsterweg stop, an operating concept with a further intermediate end point on line 2 has become possible, which enables the use of three TW 3000 courses on this line.

The plans for the other lines are not yet concrete.

  • Line 6: The southern section ( D-South ) has already been built with elevated platforms. The Nordstadt station stop is still missing on the northern section ( C-North ) . Completion is planned for the early to mid-2020s.
  • Line 10: There are still five stops without elevated platforms, Glocksee is to open in 2023, all others are to be made barrier-free by the mid-2020s.

There are still numerous stops without elevated platforms on lines 1 and 9, the expansion of which is not mentioned in the 2015 local transport plan, so that railcars with folding steps will have to be used here for the foreseeable future.
