First generation
The first ICE trains were the trainsets of ICE 1 (power cars: Class 401), which came into service in 1989. The first regularly scheduled ICE trains ran from 2 June 1991 from Hamburg-Altona via Hamburg Hbf–Hannover Hbf–Kassel-Wilhelmshöhe–Fulda–Frankfurt Hbf–Mannheim Hbf and Stuttgart Hbf toward München Hbf at hourly intervals[12] on the new ICE line 6. The Hanover-Würzburg line and the Mannheim-Stuttgart line, which had both opened the same year, were hence integrated into the ICE network from the very beginning.
Due to the lack of trainsets in 1991 and early 1992, the ICE line 4 (Bremen Hbf–Hannover Hbf–Kassel-Wilhelmshöhe–Fulda–Würzburg Hbf–Nürnberg Hbf–München Hbf) could not start operation until 1 June 1992. Prior to that date, ICE trainsets were used when available and were integrated in the Intercity network and with IC tariffs.
In 1993, the ICE line 6 ' s terminus was moved from Hamburg to Berlin (later, in 1998, via the Hanover-Berlin line and the former IC line 3 from Hamburg-Altona via Hannover Hbf–Kassel-Wilhelmshöhe–Fulda–Frankfurt Hbf–Mannheim Hbf–Karlsruhe Hbf–Freiburg Hbf to Basel SBB was upgraded to ICE standards as a replacement).
Second generation
From 1997, the successor, the ICE 2 trains pulled by Class 402 powerheads, was put into service. One of the goals of the ICE 2 was to improve load balancing by building smaller train units which could be coupled or detached as needed.
These trainsets were used on the ICE line 10 Berlin-Cologne/Bonn. However, since the driving van trailers of the trains were still awaiting approval, the DB joined two portions (with one powerhead each) to form a long train, similar to the ICE 1. Only from 24 May 1998 were the ICE 2 units fully equipped with driving van trailers and could be portioned on their run from Hamm via either Dortmund Hbf–Essen Hbf–Duisburg Hbf–Düsseldorf Hbf or Hagen Hbf–Wuppertal Hbf–Solingen-Ohligs.
In late 1998, the Hanover–Berlin high-speed railway was opened as the third high-speed line in Germany, cutting travel time on line 10 (between Berlin and the Ruhr valley) by 2½ hours.
The ICE 1 and ICE 2 trains' loading gauge exceeds that recommended by the international railway organisation UIC. Even though the trains were originally to be used only domestically, some units are licensed to run in Switzerland and Austria. Some ICE 1 units have been equipped with an additional smaller pantograph to be able to run on the different Swiss overhead wire geometry. All ICE 1 and ICE 2 trains are single-voltage 15 kV AC, which restricts their radius of operation largely to the German-speaking countries of Europe.
Third generation
To overcome the restrictions imposed on the ICE 1 and ICE 2, their successor, the ICE 3, was built to a smaller loading gauge to permit usability throughout the entire European standard gauge network, with the sole exception being the UK's domestic railway network. Unlike their predecessors, the ICE 3 units are built not as trains with separate passenger and power cars, but as electric multiple units with underfloor motors throughout. This also reduced the load per axle and enabled the ICE 3 to comply with the pertinent UIC standard.
Initially two different classes were developed: the Class 403 (domestic ICE 3) and the Class 406 (ICE 3M), the M standing for Mehrsystem (multi-system). Later came Class 407 and Class 408. The trains were labelled and marketed as the Velaro by their manufacturer, Siemens.
Just like the ICE 2, the ICE 3 and the ICE 3M were developed as short trains (when compared to an ICE 1), and are able to travel in a system where individual units run on different lines, then being coupled to travel together. Since the ICE 3 trains are the only ones able to run on the Köln-Frankfurt high-speed line with its 4.0% incline at the allowed maximum speed of 300 km/h, they are used predominantly on services that utilise this line.
In 2009 Deutsche Bahn ordered another 16 units – worth € 495 million – for international traffic, especially to France.
The Erfurt–Leipzig/Halle high-speed railway, which opened in December 2015, is one of three lines in Germany (the others being the
Fourth generation
Procurement of ICx trainsets started c. 2008 as replacements for locomotive hauled InterCity and EuroCity train services - the scope was later expanded to include replacements for ICE 1 and ICE 2 trainsets. In 2011 Siemens was awarded the contract for 130 seven car intercity train replacements, and 90 ten car ICE train replacements, plus further options - the contract for the ten car sets was modified in 2013 to expand the trainset length to twelve vehicles. The name ICx was used for the trains during the initial stages of the procurement; in late 2015 the trains were rebranded ICE 4, at the unveiling of the first trainset, and given the class designation 412 by Deutsche Bahn.
Two pre-production trainsets were manufactured and used for testing prior to the introduction of the main series.
ICE T and ICE TD
Simultaneously with the ICE 3, Siemens developed trains with tilting technology, using much of the ICE 3 technical design. The class 411 (seven cars) and 415 (five cars) ICE T EMUs and class 605 ICE TD DMUs (four cars) were built with a similar interior and exterior design. They were specially designed for older railway lines not suitable for high speeds, for example the twisting lines in Thuringia. ICE-TD has diesel traction. ICE-T and ICE-TD could have be operated jointly, but this has not been done routinely.
ICE T
A total of 60 class 411 and 11 class 415 have been built so far (units built after 2004 belong to the modified second generation ICE-T2 batch). Both classes work reliably. Austria's ÖBB purchased three units in 2007, operating them jointly with DB. Even though DB assigned the name ICE-T to class 411/415, the T originally did not stand for tilting, but for Triebwagen (railcar), as DB's marketing department at first deemed the top speed too low for assignment of the InterCityExpress brand and therefore planned to refer to this class as IC-T (InterCity-Triebwagen). The trainsets of the T series were manufactured in 1999. The tilting system has been provided by Fiat Ferroviaria, now part of Alstom. ICE T trains can run at speeds of up to 230 km/h (143 mph).
In April 2025, Deutsche Bahn announced the gradual retirement of the 5-car Class 415 from June 2025.[18]

ICE TD
Deutsche Bahn ordered 20 units of ICE-T with diesel engines in 2001, called Class 605 ICE-TD. The ICE-TD was intended for certain routes without electric overhead cables such as Dresden-Munich and Munich-Zürich lines. However, the Class 605 trains (ICE-TD) experienced many technical issues and unanticipated escalation in operating cost due to the diesel fuel being fully taxed in Germany. They were taken off revenue service shortly after delivery. During the 2006 FIFA World Cup, the ICE-TD trains were pressed temporarily into supplementary service for transporting fans between cities in Germany.
At the end of 2007, ICE-TD trains were put into revenue service for the lines between Hamburg and Copenhagen as well as Hamburg and Aarhus. A large part of the Danish railway network had not been electrified so DSB (Danish State Railways) used the diesel-powered trains. When DSB ordered the new IC4 train sets, the company did not anticipate the long delay with the delivery and the technical issues with the train sets. To compensate for the shortage of available trains, DSB leased the ICE-TD while the delivery and technical issues with IC4 were being addressed. The operating cost was much lower due to the lower fuel tax in Denmark. After the issues with IC4 were resolved, the ICE-TD fleet was removed from revenue service and stored.
Deutsche Bahn retired the entire ICE TD fleet in 2018.[19]
Differences in train layouts
Livery
A notable characteristic of the ICE trains is their colour design, which has been registered by the DB as an aesthetic model and hence is protected as intellectual property.[25] The trains are painted in Pale Grey (RAL 7035) with a Traffic Red (RAL 3020) stripe on the lower part of the vehicle. The continuous black band of windows and their oval door windows differentiate the ICEs from any other DB train.
The ICE 1 and ICE 2 units originally had an Orient Red (RAL 3031) stripe, accompanied by a Pastel Violet stripe below (RAL 4009, 26 cm wide). These stripes were repainted with the current Traffic Red between 1998 and 2000, when all ICE units were being checked and repainted in anticipation of the EXPO 2000.
The "ICE" lettering uses the colour Agate Grey (RAL 7038), the frame is painted in Quartz Grey (RAL 7039). The plastic platings in the interior all utilise the Pale Grey (RAL 7035) colour tone.
Originally, the ICE 1 interior was designed in pastel tones with an emphasis on mint, following the DB colour scheme of the day. However, ICE 1 trains were refurbished in the mid-2000s and now follow the same design as the ICE 3, which makes heavy usage of indirect lighting and wooden furnishings.
The distinctive ICE design was developed by a team of designers around Alexander Neumeister in the early 1980s and first used on the InterCityExperimental (ICE V). The team around Neumeister then designed the ICE 1, ICE 2, and ICE 3/T/TD.
Trainset numbers
While every car in an ICE train has its own unique registration number, the trains usually remain coupled as fixed trainsets for several years. For easier reference, each has been assigned a trainset number that is printed over each bogie of every car. These numbers usually correspond with the registration numbers of the powerheads or cab cars.
Interior equipment
The ICE trains adhere to a high standard of technology: all cars are fully air-conditioned and nearly every seat features a headphone jack which enables the passenger to listen to several on-board music and voice programmes as well as several radio stations. Some seats in the 1st class section (in some trains also in 2nd class) are equipped with video displays showing movies and pre-recorded infotainment programmes. Each train is equipped with special cars that feature in-train repeaters for improved mobile phone reception as well as designated quiet zones where the use of mobile phones is discouraged. The newer ICE 3 trains also have larger digital displays in all coaches, displaying, among other things, Deutsche Bahn advertising, the predicted arrival time at the next destination and the current speed of the train.
The ICE 1 was originally equipped with a passenger information system based on BTX, but this system was eventually taped over and removed in the later refurbishment. The ICE 3 trains feature touch screen terminals in some carriages, enabling travellers to print train timetables. The system is also located in the restaurant car of the ICE 2.
The ICE 1 fleet saw a major overhaul between 2005 and 2008, supposed to extend the lifetime of the trains by another 15 to 20 years. Seats and the interior design were adapted to the ICE 3 design, electric sockets were added to every seat, the audio and video entertainment systems were removed and electronic seat reservation indicators were added above the seats. The ICE 2 trains have been undergoing the same procedure since 2010.
ICE 2 trains feature electric sockets at selected seats, ICE 3 and ICE T trains have sockets at nearly every seat.
The ICE 3 and ICE T are similar in their interior design, but the other ICE types differ in their original design. The ICE 1, the ICE 2 and seven-car ICE T (Class 411) are equipped with a full restaurant car.
Maintenance
The maintenance schedule of the trains is divided into seven steps:
Maintenance on the ICE trains is carried out in special ICE workshops located in Basel, Berlin, Cologne, Dortmund, Frankfurt, Hamburg, Leipzig[26] and Munich. The train is worked upon at up to four levels at a time and fault reports are sent to the workshops in advance by the on-board computer system to minimize maintenance time.
- 1) Every 4,000 kilometres, an inspection taking about 1½ hours is undertaken. The waste collection tanks are emptied and fresh water tanks are refilled. Acute defects (e.g. malfunctioning doors) are rectified. Safety tests are also conducted. These include checking the pantograph pressure, cleaning and checking for fissures in the rooftop insulators, inspecting transformers and checking the pantograph's current collector for wear. The wheels are also checked in this inspection.
- 2) Every 20,000 kilometres, a 2½ hour inspection is conducted, called Nachschau. In this inspection, the brakes, the Linienzugbeeinflussung systems and the anti-lock brakes are checked.
- 3) After 80,000 kilometres, the train undergoes the Inspektionsstufe 1. During the two modules, each lasting eight hours, the brakes receive a thorough check, as well as the air conditioning and the kitchen equipment. The batteries are checked, as well as the seats and the passenger information system.
- 4) Once the train has reached 240,000 kilometres, the Inspektionsstufe 2 mandates a check of the
