機場捷運軌道醫生 Dr. Yellow of the TIAA MRT System
軌道線形檢測車外觀。

機場捷運面對營運路線長達51.03公里的軌道,在列車通過之際所產生的各種狀況,若僅透過夜間短短的維修時段,是難以用人員步巡方式,找出可能影響日後行駛路徑之任何變化所引發的不舒感或輪軌噪音,因此自動化機械-軌道線形檢測車就擔負這個重責,以先進且高精度的量測設備,配合電腦繪圖輸出,提供養護單位即時、可靠的各項數據,做為維修軌道元件預防性檢修或調整之最佳利器,堪稱是機場捷運之軌道醫生。
機場捷運軌道線形檢測車係由義大利VAIA CAR製造商所生產,型號為CF-250D,本檢測車將整合模組化之檢測系統,安裝於具備雙向行駛及行車動力之車輛上,總重約25.8噸,使用柴油引擎,正線行駛最大速度45km/h,機廠行駛最大速度25km/h,執行人員編制為3人,2人駕駛,1人負責量測系統。
檢測車係以非接觸方式量測軌道左右鋼軌軌距、線形、縱向水平、橫向水平、超高(傾斜度)、扭曲(平面性)等幾合數據,此量測系統亦可以量測內側鋼軌輪廓、側向磨耗、踏面磨耗、整個軌頭表面之縱向缺陷及鋼軌波狀磨耗等功能。
檢測頻率為每半年完成全線軌道線形量測1次,當資料下載後,可供軌道維修人員瞭解軌道線形狀態,並做即時養護,以維持行駛時之平穩舒適。

In the face of 51.03 kilometers of operation rail and all the possible situations when the train is passing through, the maintenance of the TIAA MRT System cannot be achieved by personnel patrol in the short period of maintenance duration during nighttime. Therefore, the automated machinery-track recording car is utilized to find every possible factor and track point that may result in discomfort or wheel/rail noise in future operation. The track recording car used high-precision measurement equipment with the help of computer graphic output to provide the maintenance unit with immediate and reliable data. This data can be used for prevention repair or adjustments for rail components. Consequently, the automated machinery- track recording car is also known as Dr. Yellow of the TIAA MRT System.
The track recording car adopted the CF-250D model manufactured by VAIA CAR from Italy. The design of the car is a two-way auto-powered vehicle with an integrated modular examination system. The total weight of the car is 25.8 tons. It is equipped with a diesel engine that can reach maximum speed of 45 km/h on the main line and 25 km/h in the depot. Operational personnel are 3 persons with 2 as drivers and one responsible for the measurement system.
The track recording car used non-contact method to measure the gauge, alignment, longitudinal level, horizontal level, cant (tilt angle), snaking (flatness) and other geometric data for the left and right rail. The measurement system can also measure inner rail profile, lateral wear, tread wear, longitudinal defects on the entire rail surface, rail wavy wear and other factors.
The inspection frequency should be one rail alignment measurement for the entire line every 6 months. Subsequent to data download, the maintenance personnel can grasp the alignment condition of the rail and conduct immediate maintenance if necessary to maintain the smoothness and comfort of operation.
