Braking Overview/zh-hant

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。

軔機控制裝置施加緊軔的操作方向幾乎總是遠離司機員。這樣一來，在緊急情況下司機員可以向前推動所有操縱桿，而無需考慮個別控制裝置的操作方向。

軔機系統的種類有：

貫通軔機：
用於減速或停止整組列車，即「自動空氣軔機」。

Risks

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.
