The ICM series (Intercitymaterieel) of NS is an electric railcar from 1977 to 1994, the intercity traffic. With a total of 144 units built, it still represents the backbone of high-speed traffic within the Netherlands to this day.
They are popularly called Koploper (literally "head runner") because of the transitions on the front of the carriages . The driver's cab is located in a panoramic cockpit above the transition, which gives this car a very beefy appearance. Until 2005 it was possible to switch from one part of the train to the other while on the move.
history
The ICM was developed as part of "Plan Z" to modernize the rolling stock of the NS. In 1977, Talbot in Aachen produced seven prototypes of a three-part railcar for fast, comfortable intercity traffic. First they were used on the Eindhoven - Venlo route , then they also drove between Amsterdam and Nijmegen . They were subsequently given the designation ICM-0. In 2003 they were z-placed .
In 1983, the series production of what is now known as the ICM-1 began. Compared to the prototypes, it has numerous improvements (e.g. improved ventilation of the passenger compartment). From No. 4051 chopper controls were installed and the type designation changed to ICM-2.
From 1990 the (previously three-part) ICMs were delivered as four-part models (series ICM-3 and ICM-4) with magnetic rail brakes .
modernization
From November 2006, the intercity equipment of the three-part trains (series 4011-4097) was modernized. In April 2007, the first multiple unit was delivered by NedTrain Betriebswerk Haarlem and entered into regular service. In order to distinguish between the multiple units that have not yet been modernized, the modernized multiple units are referred to as ICMm. These trains have been completely refurbished, with around 13% more seats. In addition, the first class differs more clearly from the second class: the first class has red seats, the second class blue like other modernized vehicles and newly built vehicles from 2006. In addition, the ICMm is equipped with additional facilities such as a wheelchair toilet, an air conditioning system, passenger information displays, a digital course board and a static converter instead of the previous motor generator. The modernization of the three-part multiple units cost 190 million euros.
Externally, the upgraded equipment was best distinguished from the non-modernized equipment by rounding the blue bar around the windows rather than a straight end and the closed windows in line with the side wall. The windows can no longer be opened. The train numbers have been moved to the track changers to make them less prone to graffiti. The name "Koploper" has disappeared.
The through-heads were removed for all trains during this revision, the two outer doors were replaced by a closed plastic plate. The not yet modernized ICM-IV 4206 and 4248 had received such a plate when repairing collision damage to one of the main doors, as the main door had been damaged in a collision. The total weight of a multiple unit is reduced by around 1000 kilograms if both pass-through head constructions are replaced by plastic cover plates. This has a positive effect on energy consumption and thus CO 2 emissions per kilometer driven.
When the "Koplopers" were modernized, NS met with a lack of understanding, as the number of toilets was halved. Criticism came from people with intestinal diseases and parents with children, among others. The NS did not respond to these complaints.
The 4011 multiple unit was the first to be modernized in November 2006 and was put into operation on April 16, 2007 after tests in the climatic chamber in Vienna and a series of test drives, controls and instructions to the staff. The very first day of operation was on the Intercity line 1500 (Amsterdam - Amersfoort - Deventer). The next train, the 4012, was only completed in May 2007 and did not form a fully modernized train with the 4011 as planned.
Due to technical deficiencies, the first five overhauled multiple units normally ran on line 1500, since this technical deficiency has been remedied, they no longer work in a fixed cycle. They can mainly be seen on the routes Amsterdam - Amersfoort, The Hague - Groningen, The Hague - Enschede, Schiphol - Groningen, Schiphol - Leeuwarden, Schiphol - Enschede, Rotterdam - Deventer and Rotterdam - Leeuwarden.
The conversion of the three-part Koplopers (the 40xx series) lasted until the 2nd quarter of 2010. The 4205 multiple unit was the first four-part multiple unit on February 22, 2009 in the Haarlem workshop for modernization and was put into operation at the beginning of January. After that, the 4203 served as a second multiple unit, the first being the option for wireless internet and current travel information (OBIS system). In February 2010, the series revision of the four-part multiple units began. It was noticeable that the pairs were no longer entered in numerical order for revision. The last ICMm (4240) was delivered on October 6, 2011.
In early 2012, NedTrain began replacing seat covers in 2nd class. These proved difficult to keep clean and were replaced by plastic-like seat covers.
commitment
The ICMs are primarily used as intercity trains on various routes throughout the Netherlands, less often as a stoptrein ( regional train ) in rush hour and even as a night train between Utrecht and Rotterdam . The main areas of use are the intercity trains between Groningen, Leeuwarden and Enschede on the one hand and Schiphol, The Hague and Rotterdam on the other. In Zwolle and Utrecht these train runs are winged or combined.
