Metro Train Simulation

Allout Run Simulation

Allout Run of Train :

Allout run of train means full traction upto maximum service speed, appropriate traction to maintain maximum service speed (i.e. to neutralize the effect of train resistance) followed by full service brake. Train operations in allout run mode give maximum time saving and take minimum running time. However, propulsion equipment of the train consume maximum energy from power supply system in allout run mode. Please input the following parameters for Allout Run simulation :



# NOTE: Please read Para 'Limitations of online Allout run simulation tool'. This is an online demo simulation tool and results of online allout run simulation tool may have some error due to these limitations. However, our offline software tools do not have such limitations and provide much accurate simulation results. For detailed description of technical terms used in this simulation tool, please read 'Technical Terms' & 'Performance Parameters' sections of this website.

Limitations of online Allout Run Simulation Tool

1.
Level track is considered for simulation. Gradient Resistance & Curve Resistance is not considered.
2.
Effect of speed restrictions can not be calculated.
3.
Jerk effect is not considered.
4.
No Brake activation time is considered.
5.
Starting resistance of train is not considered.
6.
% Regenerated Power, SEC, Current & Power are calculated based on combined propulsion equipment efficiency instead of individual propulsion equipment efficiency.
7.
All shapes of TE vs Speed graph can not be generated in this simulation tool. TE vs Speed graph has two quadrant portion only. In first quadrant, TE is inversely proportional of speed & in second quadrant, TE is inverse quadratic of speed. Other relation between TE and Speed can not be generated.
8.
Single deceleration value is considered in complete service speed range.
