Abstract
The track plinth is constructed so as to provide support for rail fasteners to clamp down the

running rail. The aim of this article is to compare the construction characteristics of two construction
methods. The first one is "the steel mold formwork" which is utilized on the section of the Nangang
line east of Taipei Main Station; the other one is "GSF mold formwork" which is adopted on the

Tucheng line. The article also depicts the development of key technology for the monolithic plinth
construction on the Xin-Lu line.

Keywords: bottom up method, top down method, baseplate bearing surface, refurbishing
