Xinbeitou branch line


The Taipei Metro Xinbeitou branch line is an elevated, high-capacity branch line of the Tamsui Line. It first opened for service on 28 March 1997. The line is long and consists of two stations.

History

The origins for the line can be traced as far back as 1916, where its predecessor line of a similar route was built and operated by the Taiwan Railway Administration. It was last operated on 15 July 1988 by diesel units before ceasing service for construction of the metro line. On 28 March 1997, the line re-opened for service as part of the Taipei Metro.

Line Operations

The operation of the line has been problematic since its opening. Complaints of noise pollution by residents along the line have led to severe restrictions. Barely six months after the line's opening, train frequency had to be reduced. On 1 November 1998, the number of cars operating on the line was reduced from six to three. Up until 2007, the operating hours were limited to between 7 am and 9 pm only. Trains currently still operate with a speed limit of due to flange on the line's sharp curves.
TRTS completed the installation of the sound-proofing barrier along the line by 2006, and on 14 September 2007 extended its operating hours to between 6 am and midnight. It was hoped that if the noise standards were deemed to be at an acceptable level that the current Orange Line trains on the Tamsui Line could operate on the Xinbeitou Line instead. Trains operate at a maximum headway of one per 7–8 minutes during peak hours.
It has been reported that the line is operating at a loss. A proposal was put forth in 2005 that a maglev train operation would solve the problem of noise pollution, but its feasibility on operating costs became a subject of ridicule.

Rolling stock

A modified C301 originally operated on the line in a 3-car formation, making it unique on the system. From 2007 onwards, the train was replaced by a purpose-built C371 of a similar length.
