Semantics / Bedeutung
The element <trainEngine> contains the acceleartion values for the entire train or train part. These values may be used for a rough estimation of runtime. The user has to ensure that the values are consistent with any acceleration values given for single vehicles forming this formation. The values shall be based on typical load situation of the formation and considering no gradient or curve as additional resistance.
Im Element <trainEngine> sind die Beschleunigungswerte für den Zug bzw. Zugteil enthalten. Diese Werte können z.B. für Abschätzungen von Fahrzeiten verwendet werden. Der Nutzer muss dafür sorgen, dass die Werte hier konsistent zu evtl. verfügbaren Werten der Einzelfahrzeuge sind. Die Werte sollten die typische Beladungssituation des Zuges oder Zugteils bei einer Fahrt in der Ebene berücksichtigen. Das heißt, es werden keine zusätzliche Fahrwiderstände aus Neigungen oder Kurven mit eingerechnet.
Attributes of trainEngine / Attribute von trainEngine
- trainMeanAcceleration: This is the mean value of acceleration in metres per square second this formation can achieve. The average value shall consider the entire speed range the formation is working in.
- trainMaxAcceleration: This is the maximum value of acceleration in metres per square second this formation can achieve. Typically the maximum is achieved at low speed right after start.
- trainMinTimeHoldSpeed (introduced with version 2.4): This is the minimum time a train shall be able to maintain its speed after acceleration before it must brake otherwise no acceleration is allowed. This feature is used by some railways and only applies for punctual trains, e.g. traveling over 40 km/h. This rule gives a more energy efficient and passenger comfortable driving style.
