ICx is a Deutsche Bahn project to procure up to 300 inter-city trains to replace its existing fleets used on long-distance passenger services in Germany. The first ICx electric multiple unit trainsets will replace Intercity/Eurocity rolling stock, followed by ICE 1 and ICE 2 trains by 2025. The ICx trains will be used on inter-city routes where DB believes Intercity-Express trainsets specifically designed for high speed operation are not suitable.
On 25 January 2010, DB named Siemens Mobility preferred bidder for the ICx contact, beating Alstom. and on 9 May 2011 DB and Siemens signed a framework contract for up to 300 ICx trains to be supplied by 2030. Of these, 130 were to be ordered straight away, with 90 to follow taking the value to €6bn. DB also has an option to order another 80 sets.
Siemens has awarded Bombardier Transportation a framework contract to support the project, worth €1.3bn for the initial 130 trains and €2.1bn for 220. This includes aerodynamics, Flexx Eco unpowered bogies, and supplying bodyshells from its Görlitz plant with driving vehicle assembly at Hennigsdorf.
It is not known whether the push to use Bombardier's bogies was an act of protectionism: - Bombardier's relevant bogie plant is in Siegen, Germany whereas Siemens' is in Graz, Austria.
Construction will start in 2013, with two pre-production trains delivered in 2016 for 14 months of trial operation.
The initial order covers two types of trainset K1n seven-car 230 km/h sets with three powered vehicles to replace locomotive-hauled IC trainsets, and K3s 10-car 249 km/h trains with five power cars to replace ICE1 and ICE2 trainsets. All will have a restaurant and bistro car, family area and bicycle spaces.
On March 5, 2013, DB announced that it was approving a 12 car train configuration that would raise capacity over, and replace in the base order, the existing 10 car train. Capacity would increase by 106 seats to a new total of 830 seats. This was done in anticipation of growing ridership for DB's long distance services that would be run with the 10 car trains.
