制軔概述
Appearance
軔機(即煞車)是安裝在軌道車輛上,用於使車輛減速、停下、或維持車輛靜止的裝置。動力車輛和其他軌道車輛通常搭載著幾種不同的軔機系統,這些不同的軔機系統各自適用於不同情境。它們能分別以位於駕駛室內或車輛外部的操縱桿或舵輪進行操作。
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.
