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 (IC) and InterRegio (IR) trains. DB assigned the name IC T to the project, with "T" standing for Triebzug (multiple unit). This development resulted in the ICE T.
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.

Famous quotes containing the word development:
“The work of adult life is not easy. As in childhood, each step presents not only new tasks of development but requires a letting go of the techniques that worked before. With each passage some magic must be given up, some cherished illusion of safety and comfortably familiar sense of self must be cast off, to allow for the greater expansion of our distinctiveness.”
—Gail Sheehy (20th century)
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
