Origin of the ICK
Because of the physical shortage that was created in the year 2000, the NS 150 carriages of the type Bm235 bought from Deutsche Bahn. These carriages are at Partner für Fahrzeug Facilities (PFA) converted in Weiden and adapted to the needs of the NS as the 'central door-locking system. The 150-Bm235 carriages emerged 96 B, 36 A and 18 BD-carriages. When the conversion for this car series so distinctive layout remained a side corridor and only retain sections, although it was still the partition between two sections removed in 1st class. In the big coupe were then placed nine seats, the legroom in the 1st class ICK is very spacious. The BD-carriage were a luggage room, a great room and a disabled toilet for the disabled built. The large windows (that were previously open for half) were limited. Finally, the coaches painted in yellow / blue NS Intercity livery. The acquisition and conversion of the railway carriages took nearly 60 million.

Equipment Shortage
The coaches were initially designed to absorb the temporary material shortage until there was sufficient IRM available. First, the ICFs used in combination with other types of carriages, the carriages were later used only in complete ICK-trains. In practice, the coaches are interim set aside copies came back into service, especially since the introduction of the 2007 timetable, with more material than was necessary also continue to drive after the episode of V-IRM, and
The inflow of VIRM-4 double-decker carriages the ICK are no longer needed and they are set aside from 20 April 2009. In Nijmegen, they are now in a yard.

The deployment of the ICK trains
From February 4, 2002, the very first 14 ICK-carriages in the Intercity between The Hague and Venlo / Heerlen. Later also the route to Maastricht-Haarlem. In September 2002 all carriages were employed.
In 2005 it was decided to divide the ICFs in trunks so this would provide for maintenance and failure of wagons, which could be at the expense of punctuality. Fewer problems
Each tribe has its own number. There are three types of logs:
• Loose B (second class coach) numbered in the 5000 series
• BD (B +) (or two times a second class, which always with a disabled toilet) numbered in the 5300 series
• B + A + B (second class, first and second class) numbered in the 5400 series

The basic number is applied to the adjusting bar next to the carriage number.

The ICK-carriages are all in maintenance in the NedTrain maintenance in Maastricht.
