認識軌道警衝標 Introduction to the Rail Fouling Points
設置於正線路段之警衝標。

警衝標是防止車輛擦撞的警示標誌,為軌道的標識與標誌之一。因應列車或工程車輛調度需求,在道岔岔心後端設立警衝標,規範工程車或列車駕駛員行駛不同股道欲進入同一道岔時,工程車或列車車輛停駐在警衝標前端不得超過此標誌,避免與分歧鄰線之車輛發生擦撞,因此,警衝標裝設位置需考量車輛界限尺寸及安全餘裕。以機場捷運為例,警衝標位置位於道岔分岐之後端兩股軌道之間,且與兩相鄰之軌道中心線水平距離至少為3.8公尺再加上預留之車輛偏倚量。機場捷運正線路段之警衝標係以20x20公分之金屬鈑鎖固於混凝土道床,機廠區域之警衝標則以20x20x40公分之混凝土柱埋置於道碴道床中,表面均塗以明顯之紅色漆,以利識別。

The fouling point is one of the rail warning signs designed for preventing vehicle collision. In response to the dispatching demands of trains or engineering vehicles, the fouling points are installed at the back end of the turnout crossing. The fouling points are used to regulate the drivers of trains or engineering vehicles to stop before the fouling point when entering the same turnout from different tracks to avoid collision with vehicles from adjacent tracks. Therefore, the locations of the fouling points need to consider the vehicle gauge and also the safety margin. Taking the TIAA MRT System as an example, the position of the fouling point is located between the two rails at the rear end of the turnout and is at least 3.8 m in horizontal distance from the two adjacent track centerlines plus the reserved vehicle sway. The fouling points of TIAA MRT main line are locked to the concrete track bed with 20x20 cm metal sheets; as for the fouling points of the depot areas are locked to the ballast bed with 20x20x40 cm concrete pillars. The surfaces are all coated with clear red paint to facilitate identification.
