制軔概述

軔機，即煞車，是安裝在鐵路車輛上 ，用於使車輛減速、停下或維持車輛靜止的裝置。動力車輛和無動力車輛通常搭載了多種於不同情境有著相應優勢的制動系統。這些系統通常得透過位於車輛駕駛室 中或車身外部的操縱桿、舵輪進行操作。

軔機控制裝置緊軔的操作方向幾乎總是遠離司機員。這樣一來，遭遇緊急情況時，司機員僅須向前方推動所有操縱桿，而無需考慮個別控制裝置的操作方向。

制動系統的類型有：

• 貫通制動 - 用於使整組列車減速或停止。
• 單獨制動 - 用於單獨使機車 等車輛減速或停止。
• 動力制動 - 用於輔助軔機始列車減速。
• 手軔機制動 - 用於確保整組列車或單一車輛永久維持靜止。

風險

Some of the main risks associated with brakes are:

• Parked trains turning into runaways due to brake cylinder leaks and misapplied handbrakes .
• Forgotten applied handbrake(s) resulting in hindered pulling power .
• Badly set up brake pipe valves leading to limited train brake availability.
• Traction loss resulting in wheelslide if brakes are applied too hard in wet conditions .
• Prolonged mechanical brake usage resulting in brake shoe overheating and loss of braking power.
• Incorrectly setup brake cutout valves , resulting in dysfunctional train brakes .
• Excessive dynamic brake use leading to powertrain overheating .

Warnings

Depending on the session difficulty settings , a flashing warning light above the brake pipe gauge indicates certain problems with the braking system. They are:

• There is a handbrake applied somewhere on the train.
• One of the brake pipe valves is incorrectly setup somewhere on the train.
• There are more than one brake control devices cut in , or none is, on the train.
