Honganiemi Underground

The Honganiemi Underground is the public rapid transit system serving Honganiemi, the capital of Dryicor. The underground, commonly referred to by locals as the 'Metro', has six main lines, represented by different colours on the famous map.

The Metro is the most popular way to get around due to the trains being heated, contrasting with the icy Dryicoran climate. The Underground is free for over-65s and under-25s, with small fees for locals, upon which tourists pay 10% extra if over 25.

Fee system
Upon one's 24th birthday, they are sent an Underground Ticket (commonly referred to as the 'Metrokortti' - the 'Metro card'). The UT should be topped up before they reach the age of 25. 100 Kr's (around $11)'s worth of tickets are given for free, after this is used up they must pay more to keep using the service. Tourists are encouraged to buy a Temporary Underground Ticket, which can be topped up as a local would (except these do not have the automatic 100 Kr). Free travel is given to locals aged under 25.

When the holder turns 65 (if a local), all money that is currently in their account is taken by the Government (as such there are often notices at Underground stations reminding those who are turning 65 to withdraw their UT deposit) and their UT is invalidated. Their rides are now free.

From 1954 until 2017, holders of a passport would be given the same fares as a Dryicoran holder: since 2017 they have been given the same fares as one outside of it would.

Lines and network
The network consists of six main lines, each represented on the map by a different colour. These are the Central Line (blue), the Triangle Line (orange), the Western Line (green), the Supplementary Line (purple), the Airport Shuttle (silver) and the National Line (red). Colloquially, these are often known by their respective colours by locals.

The first to be built in 1926 was the Central Line: this goes from Western Station in the west to Baird House Station in the east. The Triangle Line, built in 1932, goes from Northern Station and goes into the centre of the city and then trails along the south in an extension added in the 1990s. The Western Line was opened in 1956 and goes from Koskinen Station in the south and trails the west of the city before terminating at the city centre. The Airport Line was built to serve Honganiemi Airport when it was built in 1972 and functions as a quick shuttle route from the north of the city, then going to the east then finally ending at the airport in the south-east. The Supplementary Line was built in the 1980s to ease congestion on the central part of the Central Line, and runs parallel to it. The Millennium Line was opened in 2000 and stops at every terminus of each line, encircling the city, to connect passengers seamlessly with other routes of transportation such as motorways and railway services out of the capital.
