Jarrut ovat kiskoajoneuvoissa olevia laitteita, joita käytetään niiden hidastamiseen, pysäyttämiseen tai paikallaan pitämiseen. Moottorikäyttöisessä ja muussa kuljetuskalustossa on tyypillisesti useita erilaisia jarruja, joista jokainen on käytännöllinen tiettyyn tarkoitukseen. Niitä kutakin ohjaa yksilöllinen ohjauslaite, yleensä vipu tai kampi, joka voi sijaita ohjaamon sisällä tai ajoneuvon ulkopuolella.
Jarrut on lähes aina suunnattu poispäin kuljettajasta. Näin kuljettaja voi hätätilanteessa työntää kaikkia vipuja turvatoimenpiteenä eteenpäin ilman, että hänen tarvitsee ajatella kunkin ohjaimen omaa sääntöä.
Jarrujen tyypit ovat:
Itsetoimijarru:
Käytetään koko junan hidastamiseen tai pysäyttämiseen.
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.
