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

All attributes are inherited from tBasicBrakeType.

• brakeType: This names the type of brake producing the brake effort. According to the way of controlling the brake application one of the following can 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 using vacuum in the control pipe (Saugluftbremse). The brake shoes are pressed onto the wheels by means of athmospheric air pressure.
• 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 - brake applied by any other mechanism

• airBrakeApplicationPosition: This is the setting for the air brake application defining the time span for activation. One of the following can be selected:

• 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.

• 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.

• 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.
