Intercity Express

technology Maturity 7-9 Next article →

The Intercity Express, commonly known as the ICE, is a high-speed rail system in Germany.

It serves as the flagship service for the German state railway, Deutsche Bahn. These trains are designed for long-distance travel and high levels of comfort. Because of this, they are often marketed to business travelers and commuters as a faster alternative to flying. While the system is based in Germany, it operates cross-border services to Austria, France, Belgium, Switzerland, and the Netherlands.

The development of the ICE began with rigorous testing and experimentation. In 1985, the Deutsche Bundesbahn started trials using the InterCityExperimental, also called the ICE-V. This test train served as a showcase for high-speed technology. On May 1, 1988, the ICE-V set a new world speed record of 406.9 km/h.

This experimental unit was retired in 1996 and replaced by the ICE S for further measurements. Following discussions regarding train width, length, and onboard equipment, an order for 41 units was placed in 1988. This order grew to 60 units by 1990 to prepare for German reunification. The official ICE network was inaugurated on May 29, 1991, at the Kassel-Wilhelmshöhe station.

High-speed trains operate using different mechanical configurations. The first generation, the ICE 1, used separate power cars to pull the passenger carriages. The second generation, the ICE 2, introduced improved load balancing. These units were designed to be smaller so they could be coupled or detached as needed.

The third generation, the ICE 3, changed the mechanism entirely. Instead of separate power cars, the ICE 3 uses electric multiple units. This means the motors are located under the floor throughout the train. This design reduces the load per axle and allows the train to fit the standard European loading gauge.

Different generations of ICE trains have distinct technical capabilities. The ICE 1 and ICE 2 are single-voltage 15 kV AC systems. This limits their operation mostly to German-speaking countries. The ICE 2 can reach a maximum speed of 280 km/h.

The ICE 3 is significantly faster, with speeds reaching up to 330 km/h. The ICE 3 is also unique because it can handle the 4.0% incline on the Köln-Frankfurt high-speed line at its maximum speed of 300 km/h. Some versions, like the Class 406, were built as multi-system trains for international travel, though these were retired in April 2025 due to maintenance issues.

Specialized technology exists for specific track conditions. Siemens developed tilting technology for the ICE T and ICE TD models.

These trains are designed for older, twisting railway lines, such as those found in Thuringia, where high speeds are usually difficult. While the ICE T uses electricity, the ICE TD uses diesel traction.

The fourth generation, the ICE 4, was developed to replace older InterCity and EuroCity services. This model was rebranded from the ICx name in late 2015.

The technology behind the ICE has a massive global impact. The ICE 3 served as the development base for the Siemens Velaro family. This means the design has been exported to many different countries. For example, the Renfe Class 103 in Spain is based on this technology and can run at speeds up to 310 km/h.

Other versions of the Velaro design are used for the Beijing–Tianjin intercity railway in China, as the Velaro RUS in Russia, and in Turkey and Egypt. Even the Eurostar has used this family of trainsets.

Modern advancements continue to expand the ICE network. The ICE 3neo is a new generation of the Velaro MS design. These trains are designed for speeds of 320 km/h and began deployment in 2022.

Deutsche Bahn ordered 90 of these trains in total. The ICE 4 also provides high-capacity service, with orders for large numbers of vehicles to replace older fleets. As high-speed lines like the Erfurt–Leipzig/Halle railway open, only the third-generation trains and newer can utilize the 300 km/h line speeds. This interconnected system of high-speed tracks and advanced trains continues to shape how people move across the European continent.
