 and DSB, commonly known as the ICE TD.

Development

Following 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 comfort level raised near the ICE standard and higher speeds, with tilting electric multiple units to replace locomotive-pulled InterCity
Intercity (Deutsche Bahn)

There are Intercity routes throughout Germany, and routes generally operate with a two-hour frequency, with multiple routes giving a more...

.

Later, Deutsche Bahn also saw the need for a similar new train on its non-electrified routes, and started the ICT-VT project, with "VT" standing for Verbrennungstriebwagen (internal combustion motor car).

Deutsche Bahn pursued the development of the ICE 3

, IC T and ICT-VT projects in parallel. The trains share a general styling concept, most prominently a lounge section in the front cars with a view forward at the tracks, being separated only by a glass wall from the driver's compartment. 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 powerheads, but with peripheral underfloor motors, in order to reduce axle load (quite important for tilting trains) and increase tractive effort.

For the ICT-VT, a four-car configuration was chosen, without a restaurant car, otherwise, Deutsche Bahn aimed for a common appearance and the greatest possible technical commonality with the IC T. Even the possibility of coupling together an electric and diesel train and operate them jointly was to be provided.

Production

In 1996, Deutsche Bahn placed an order for 20 diesel multiple units with a consortium led by Siemens.

As for the ICE T

, DWA (Bombardier) produced the end cars and Siemens produced the middle cars. The ICE TD was fitted with an electro-mechanic tilting actuator system developed by Siemens, rather than the Fiat (Alstom) Pendolino hydraulic system used in the ICE T. Also, the secondary suspension between bogie and carbody is air springs rather than metal coils for higher ride comfort. A characteristic element of the Siemens system visible on the outside is the crescent-shaped top of the outer carbody supports (above the bogie center).

The tilting system also left room for electric motors on both axes in a bogie, thus every car of the Diesel-electric train has an unpowered bogie and a powered bogie (2'Bo' configuration). The power for the electric motors of the class 605 is generated by four diesel engines, one on each car, with 560 kW power each. These engines are based on engines for truck

s. Electrically, the two halves of the train form two independent power units of two cars each, with the theoretical possibility of the addition of a fifth car as middle trailer.

The first train was assembled in 1998, trials on track started in April 1999. During a test run on 13 January 2000, 222 km/h was achieved.

Shortly before the first IC T entered service in 1999, the names of the electric and diesel trains were changed to ICE T and ICE TD respectively, 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...

Service history

In 2001, all 20 units were commissioned for Deutsche Bahn, who took them as class 605. After pilot runs, the trains entered regular service on ICE line 17 between Dresden

The service life of the class 605 was rather ill-fated. The ICE TD units were plagued by technical problems from the start.

After the breaking of an axle on 2 December 2002, all remaining 19 units (one fell off a working platform) were grounded. Even though one year later the trains were admitted to service again, DB judged their operation to be overly expensive. DB must pay full diesel tax
