The IC3 (or class MF) is a Danish-built high-comfort medium/long distance diesel multiple-unit train. The sets were built by ABB Scandia (later purchased by Adtranz, which itself was subsequently acquired by Bombardier Transportation) in Randers. This train model has been operating in Denmark and Sweden since 1989. The name indicates simply that it is a three-carriage InterCity trainset.
An electrically powered four-carriage version, the IR4 was introduced between 1995 and 1998.
The IC3 is a wide articulated train made of light alloy with Jacobs bogies shared between carriages. There are two 298 kW (400 hp) engines in each end of the front and rear carriages, central car has none, giving a total of 1,192 kW (1,598 bhp).
The efficient mechanical transmissions with multiple gear ratios and high power for the 97 t (95 long tons; 107 short tons) tare weight give the IC3 good acceleration capabilities. The short distances between stations on inter-city routes in Denmark makes acceleration more important than high top speed, and so the IC3 units are geared for a top service speed of only 180 km/h (112 mph).
The front- and cab-design is the most significant feature of the IC3 (and its cousins). When viewed from the outside, the viewer will notice the large rubber diaphragm surrounding a flat cab. The cab is separate department in the train, but the table with the controls are mounted on a huge door, to which the seat is also mounted. When two or more units are coupled together in a single train, the entire front door folds away to give a wide passage, and the rubber diaphragms at the ends form a flush aerodynamic seal. The IC3 can also couple and run in tandem with the electrical version, the IR4. Up to five trainsets can be coupled together. In case of shuttle reason the IC3 can also be coupled mechanically with its Flexliner little sister IC2 but not the cousin ET-FT-ET.
Danske Statsbaner, the Danish State Railways, runs 96 IC3 sets and 44 IR4 sets. Their IC3 units are to undergo refurbishment, including engine and transmission upgrades to prepare them for regional service, when the inter-city services are taken over by their successor, the IC4.
