DBAG Class 411 and Class 415 are German tilting high-speed electric multiple-unit trains in service with Deutsche Bahn
Deutsche Bahn AG is the German national railway company, a private joint stock company . Headquartered in Berlin, it came into existence in 1994 as the successor to the former state railways of Germany, the Deutsche Bundesbahn of West Germany and the Deutsche Reichsbahn of East Germany...
(DB), commonly known as ICE T.
DevelopmentFollowing the successful inauguration of the Intercity-Express system in 1991 and the order to develop the ICE 2, in 1994 DB started plans to upgrade long-distance services using conventional lines, with higher speeds and a comfort level close to the ICE standard, using tilting electric multiple units to replace locomotive-hauled InterCity
Intercity (Deutsche Bahn)
Intercity is the second-highest train classification in Germany, after the ICE. Intercity services are loco-hauled express services, usually over long-distances. There are Intercity routes throughout Germany, and routes generally operate with a two-hour frequency, with multiple routes giving a more...

(IR) trains. DB assigned the name IC T to the project, with "T" standing for Triebzug (multiple unit).
Later, Deutsche Bahn also saw the need for a similar new train for its non-electrified routes, and started the ICT-VT project, with "VT" standing for Verbrennungstriebwagen (internal combustion motor car). This development resulted in the diesel-powered ICE TD

, IC T and ICT-VT projects in parallel. The trains share a general styling concept, notably a lounge section in the front separated only by a glass wall from the driver's compartment, with a view forward over the tracks. Technically, the trains share a lot of components and technical layout, as well as the concept of distributed traction: in contrast to the ICE 1 and ICE 2 designs, the new units were planned not with power cars, but with peripheral underfloor motors, to reduce axle load (important for tilting trains) and increase tractive effort.
At first plans were made for a three-car EMU, but in the end, capacity considerations led to a decision to create trains of two different lengths, five (later class 415) and seven (later class 411) cars, the combinations of which allow a sufficient variety of train lengths with a maximum of three trains coupled (possible variations are: 5, 7, 10, 12, 14, 15 cars total).
ProductionIn 1994, Deutsche Bahn placed an order for 40 trains, revised to 43 trains (32 of the 7-car, 11 of the 5-car version) in 1997.
The trains were produced by a consortium led by DWA and including Siemens

, Deutsche Bahn decided to upgrade its conventional line between the two cities to 230 km/h. To serve this line and increase capacity on other lines, in 2002 DB ordered an additional 28 seven-car trains from a consortium consisting of the successors of the companies in the previous one, but this time led by Siemens. This brought the total number of Class 411 trains to 60. The main changes were aimed at reducing costs.
Class 411The second (411.1), third (411.2), fifth (411.7) and sixth (411.6) cars are motorised, while the end cars (411.0 and 411.5) carry transformers supplying the next two cars. Thus each train consists of two power units of three coaches plus one unpowered middle car (411.8). The middle car can be removed, and theoretically the trains can be supplemented with an additional middle car.
Class 411, second batch
The second batch of trains (with car numbers of 411 x51-411 x78) display a number of smaller modifications, mainly to reduce purchase and maintenance costs. The most visible differences outside were the lack of a through window band with tainted glass, and LED matrix headlights. The most apparent differences inside were the scrapping of on-board radio and the replacement of the restaurant with a standing bar. The trains also offer 8 additional seats for a total of 390.
Class 415Each five-car train forms a single power unit, with three motorised middle cars (415.1, 415.7, 415.6) between two end cars (415.0, 415.5) carrying transformers.
Six trains are intended for domestic service, the other five (car numbers 415 x80-415 x84) for international service towards Switzerland, therefore they were also equipped with the Swiss train safety system and additional narrower pantographs for the Swiss network.
The first class 415 train was assembled in the summer of 1998, when testing began. Trials with the activated tilting system started in October 1998. Software errors delayed the commissioning. The first class 411 was delivered in early 1999.
Shortly before entering service, the product name of the trains was changed to ICE T, with "T" now standing for the English word tilt(ing)
A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest due to...

routes were added.
On 6 January 2004, one unit (with cars numbered 411 x06) burnt out. Only the end cars remained intact, and have been used as temporary replacements for damaged end cars of other units.
Starting in December 2004, DB took the second batch of 28 more class 411 units into service on the upgraded line between Berlin and Hamburg. This was the first time the ICE T reached its top speed of 230 km/h in regular service. DB accepted the additional trains only after they proved themselves reliable in service, with all trains delivered by the 2006 FIFA World Cup

. The trains were delivered with a standing bar in place of a restaurant; however, from 2007, all have been rebuilt with a restaurant.
Most trains have been assigned city names.
When the capacity of the Switzerland-enabled five-car trains became too low for the Stuttgart-Zürich services, in 2006 the class 415 end cars (which carry the pantographs and the train safety equipment) were switched with that of class 411 trains, thus forming seven-car trains suitable for services to Switzerland.

every two hours. Some of these trains come from Dortmund and go via Frankfurt to Vienna.
Service disruptionOn 24 October 2008, DB temporarily removed all ICE-T trains from service after a crack was found in an axle of one of the company's fleet of trains. All the trains were to be inspected for similar cracks and repaired as necessary before DB returned them to service. DB decided to sideline the trains after consultation with Siemens, Bombardier and Alstom revealed only "unclear information" about the expected life span of the axles.
At the start of November 2008, a quarter of the trains were back in service. The ultrasonic tests progressed at a speed of two trains a week, with tests on all trains expected to be finished by February 2009. Until the reason for the axle breaks is identified, the checked trains are operated with deactivated tilting system.

suggested that the axles would have to be replaced with a new design. Development, production and installation of the new axles would take up to two years.
