the day there are three trains an hour between Copenhagen and Odense. Quite unusual in the world, some trains will consist of both electrically and diesel-powered units coupled together. Being the only option for long-distance and some short-distance travel, there is no surcharge for IC and Lyntog. They have a maximum speed of 180 km/h. Additionally, there are a few IR trains during Friday and Sunday peak hours between Copenhagen and Århus. These are locomotive-run and have bilevel cars. The IC3 trains are planned to be replaced by new IC4 trains, originally in 2001. They first ran with passengers in 2008, but haven't nearly replaced the IC3 yet. It is now planned to give the IC3 stock a 10-year life extension, and to eventually scrap IC4 trains, due to the plague of poor reliability. IR4 stock (Electric version of IC3) will release IC3 stock from the Esbjerg Line, allowing some IC3 trains to replace IC4 trains. Finland In Finland, VR has operated InterCity trains between major Finnish cities since August 1988. The first routes were Helsinki–Vaasa and Helsinki–Imatra, which later expanded to all major cities and include for instance Helsinki–Tampere–Oulu–Rovaniemi, Helsinki–Turku, Helsinki–Iisalmi and Helsinki–Joensuu. InterCity trains have become the standard as the Finnish long-distance rail travel mainstay, and their predecessors, blue-carriaged express trains, are being withdrawn off the schedules. The train tickets include an additional surcharge compared to ordinary express trains: 17 to 27% depending on journey length. VR operates both ordinary InterCity trains (IC) and entirely double-decker trains (IC²). An ordinary IC train usually consists of 3 to 4 double-decker cars and 3 to 5 ordinary IC cars. In addition the train has a restaurant car. IC² trains consist only of double-decker cars and have no separate restaurant car with a sales trolley moving about in the train. However, due to high demand, VR ordered double-decker restaurant cars from Transtech in early 2011. The first carriages should be operational in 2013. All IC-trains are smoke-free. The trains run at a maximum speed of 140–160 km/h for single-decker trains and up to for double-deckers, which was VR's aim in 1988. Only the Pendolino and Allegro trains are faster than InterCity trains in Finland. France In 2006, the SNCF rebranded Corail, Téoz and Lunéa services as 'Intercités', a brand for all of their 'classic' services day and night. Germany In Germany, the InterCity network was launched in 1971 to accompany and
