Many improvement cases of Kaohsiung MRT elevated stations were aroused due to complaints from passengers that rain has caused disturbance to the waiting area. Therefore, evoked by such Kaohsiung MRT cases resulting from lack of anti-rainy facilities on elevated stations, "preventing negative impact from weather change to stations" came to be a major priority in the interface meeting of Taoyuan Metro Corp. and BOHSR. Upon weather evaluation of all stations in CE02 Tender by the supervising consultant, both Shanbi Station (A10) and Kengkou Station (A11) which are located in Lujhu Township, Taoyuan County fit the characteristics to initiate the anti-rainy facilities installation. Due to station location in the middle of vast open field and the annual northeast monsoon between November to March in the following year, station platforms and concourses are unprotected from the rain brought in by the monsoon. The installation project is described briefly as follows:
1. Installation of the anti-rainy facilities is a secondary construction to the station building itself. Thus the facility location, materials and design should correspond with the original station design. With complete discussion and evaluation, suspended glass walls were adopted to reduce open area on the platform side and provide protection for the ceiling and ancillary equipment.
2. On the other hand, since Kengkou Station (A11) adopted the double-island platform design, the above suspended glass walls are not applicable on such platforms. Thus, the conventional noise barrier windbreaks were applied to block the 15m-high platform side winds.
After completing the installation of anti-rainy facilities in Shanbi Station (A10) and Kengkou Station (A11), platform side winds were successfully blocked resulting in future normal operation of the Taoyuan Metro network.
