Brakes are devices found on rail vehicles designed to slow them down, bring them to a halt, or keep them stationary. There are several different types of braking systems that are typically present on motorized and other rolling stock, with each offering advantages for a specific purpose. They are each operated by respective control devices, usually levers or cranks that may be located inside the vehicle's cab, or on its exterior.
Application of brake control devices is almost always made to be oriented away from the driver. This is so that, in case of emergency, one can push all the levers forward as a safety measure, without needing to think of each control individually.
The types of braking systems are:
- Train brake - Used to slow down or stop trains.
- Independent brake - Used to slow down or stop individual vehicles, such as locomotives.
- Dynamic brake - Used to aid train brakes in slowing down trains.
- Handbrake - Used to ensure that a train or individual vehicle remains stationary indefinitely.
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.
