Five years after the original route opened THSRC began work to extend the network, with the construction of three new stations along the original route in the counties of Miaoli, Changhua and Yunlin, and a 4km underground extension to Taipei's Nangang District.
The new terminus at Nangang was required to help ease passenger congestion at Taipei Railway Station and provide a new interchange with conventional passenger railway and Taipei’s underground system.
Following government approval to proceed, THSRC once again appointed our Taipei office to provide our support during the associated works.
Over the course of the project, our teams provided assessments of the traction power system, track-work, signalling, automatic fare collection and new station control room at Nangang. The teams also assessed the civil engineering work at the three new stations along the route.
A key challenge was to ensure that the new extension would not degrade the safety and operational performance of the existing route. Furthermore, the team had to work within restricted possession time slots and limited trial run demonstrations, which had to be arranged around normal revenue service.
Nevertheless, the team successfully achieved approval for operation from Taiwan's Ministry of Transportation and Communications of Taiwan, with the certificate for commencement of revenue service delivered eight months ahead of schedule.
