ABSTRACT

With the expansion of the Taipei MRT road network, the MRT Circular Line route
connecting Metropolis of Taipei in the later period will pass through the densely
populated area of New Taipei City, and many places along the line need to take
small turns. Need to take into account the reduction of the sharp driving noise
generated between the wheel and rail. This article will focus on the current
excellent operational performance and experience of the Phase one of the Circle
line with a small turning radius of 45m. The Phase one of the Circle line adopts the
slewing ring bogie design with bolsters, mainly to increase the small turning radius
in addition to add track rail lubrication facilities to reduce noise, and designing
train noise-reducing wheels and wheel flange lubrication blocks, these new
facilities are very important to other MRT routes. It is the first of its kind and has
used as a feedback for the future construction with a small turning radius in the
MRT line Wanda Line and the Circular line with a small turning radius in the
North-South Circle Line.
