Semantics / Bedeutung

The element <trainBrakes> describes the type of vehicle brakes and their applciation as brake effort or deceleration. There is a distinction between normal brake operation and emergency brake application.

Das Element <trainBrakes> beschreibt die Bauart(en) und Wirkung, d.h die erzielbare Bremskraft bzw. -verzögerung, der Fahrzeugbremsen. Es wird dabei zwischen der normalen Betriebsbremsung und der Schnell-(Not-)bremsung unterschieden.

Attributes of trainBrakes / Attribute von trainBrakes

• brakeType: This names the type of brake producing the brake effort. According to the way of controlling the brake application one of the following values should be selected:

• none no brake at all
• compressedAir (pneumatic) brake system using compressed air to press the brake shoes onto the wheels or brake discs.
  "Druckluftbremse"
• vacuum brake system using vacuum in the control pipe. The brake shoes are pressed onto the wheels by means of athmospheric air pressure.
  "Saugluftbremse"
• handBrake manually applied brake by turning a handle or a lever which operates a gear/rod assembly with brake shoes
  "Handbremse"
• parkingBrake mainly spring applied brake used to keep a parking vehicle stationary
  "Feststellbremse"
• cableBrake brake applied by a cable running along the train
  "Seilzugbremse", z. B. Bauart Heberlein
• other:anything: Any value that does not fit any value from the previous enumeration list, fulfilling the constraint: at minimum two characters, whitespace is not allowed. Please, apply Dev:usingAny accordingly.
  brake applied by any other mechanism

• airBrakeApplicationPosition: This is the setting for the air brake application defining the time span for activation. Possible values are:

• N/A not applicable as brakeType is not compressedAir
• G slow activation, typical for freight trains or Merchandises
• P fast activation, typical for passenger trains with speed up to 120 km/h
• R rapid activation, typical for passenger trains with higher speed

• regularBrakeMass: This is the brake mass in metrical tons for normal brake operations of none-automatic brakes.

• regularBrakePercentage (introduced with version 2.5): This is the brake percentage related to brake mass for normal brake operations of none-automatic brakes.

• emergencyBrakeMass: This is the brake mass in metrical tons for emergency brake operations of none-automatic brakes. It differs from regular brake mass depending on auxiliary brakes.

• emergencyBrakePercentage (introduced with version 2.5): This is the brake percentage related to brake mass for emergency brake operations, differs from regular brake percentage depending on auxiliary brakes.

• maxDeceleration: This is the alternative specification of maximum possible momentary deceleration in metres per square second. Typically this value is achieved near standstill.

• meanDeceleration: This is the alternative specification of effective mean deceleration of a whole brake operation in metres per square second.
