EMUs used to be unpopular in the seventies and eighties, because they were mostly manufactured by the carriage industry, with only a few components from the locomotive industry - a train with separate power cars brought orders to both branches. In 2002 this line will be extended via the new high-speed line to Frankfurt. 16 trains of the type Talgo 350 will come from Talgo , with Adtranz and Siemens Krauss-Maffei as subcontractors for the power cars. Ten of the power cars will be built in Germany, the rest in Spain. This means that the middle cars are 279 mm long, which should not be a problem in 360 mm curves.
All cars have interior lights.
Transformer cars of 1st class 406.1 and 2nd class 406.6 will be available to extend the train. They gave up those plans however, and are now offering the ICE-VT instead. The basic set consists of end cars 1st and 2nd class and transformer cars 1st and 2nd class. The train has interior lighting with LEDs. For extending the train, a 2nd class car 406.7 will be offered.
