Surface area: 272 sq. km The Taipei urban area Population : 5 M inh. The operational metro network Lines : 6 Stations : 64 Traffic : about 1 M passengers per day Background ways. To this network will be integrated the rail link between CKS International Airport and Taipei, and the Taipei Circle Line. Capital of Taiwan with more than 5 million inhabitants for the metropolitan area, Taipei City started planning its metro network in the 1970’s, the construction in 1980’s and progressively the revenue services in 1990’s. Nowadays, the 1st stage network is totally completed and put into revenue service. This first metro network of 69 km includes 6 lines and 64 stations, with a daily passenger flow of about 1 million. A 2nd stage network has been approved by the Central Government and is now under construction. Including 7 lines and 57 stations, the second stage will add up 70 km rail- Neihu Line B2 B1 B6 B7 B3 B4 B5 B8 B9 BR2 BR1 B10 B11 The Neihu Line In 1996, the first line of the Taipei metro network to be put into commercial operation is the Mucha Line (Brown Line), an elevated Medium Capacity Transit system (VAL). As part of the 2nd stage network, the Neihu Line is an extension of the Mucha Line. The Neihu Line starts north from the existing elevated terminal station BR2. The line then goes down into tunnel to the Sungshan domestic airport with BR1 station, it turns north under the airport and Keelung River and re-emerges after B1 station. The Neihu Line continues east by viaducts crossing Neihu District to reach the terminal and depot in Nankang. There a connection is made to Nankang Line. The system definition, as well as the design of the civil works, track and depot have been carried out between 1999 and 2002. The construction has started in 2003. The revenue service is scheduled to begin in June 2008. Stations Mucha Line The Neihu Line includes 12 stations, of which 2 are underground and 10 elevated. Added to this is a maintenance depot. Infrastructure Dec. 2005 The total length of Neihu Line is about 15 km, including 4 km under tunnel and 11 km on viaduct. definition of the system-wide requirements and interfaces between systems and civil works.power supply simulation of the whole line. .design assistance for special bridges. as well as the costduration ratio.
