Evolution of Pre-operation of Taipei MRT Luzhou Line’s DFF Non-ballast
Special Trackwork Installation

Tao-Chia Wei
Abstract

Taipei MRT Luzhou line’s direct fixation fastener (DFF) non-ballast special trackwork rests
on the same type of slab as those adopted for MRT lines currently in service. Installation of the
fasteners plays a key role in the construction of successful special trackwork, in particular, the
evenness of the fastener position is a strict requirement. However, DFF features easy operation,
allows space of passage during construction as well as assured quality. In the pre-operation of
Luzhou line’s non-ballast special trackwork, after the track slab is cast in-situ, the quality of DFF
non-ballast special trackwork will depend on the procedures to build-in the anchor male cone and
the quality of the bearing surface in this crucial step in the installation stage, even though these

activities constitute only a part of the overall assembly work.
This paper addresses the work sequence and details of these two major activities, i.e. fastener
insert implanting and base-plate bearing surface finishing, which are implemented in the Taipei
MRT Luzhou line. Also, associated benefits compared with corresponding activities applied in
previous MRT construction are discussed, intending to provide a reference for future Taipei MRT
construction.
Keywords: special trackwork, implant, mortar patching
