Abstract

This paper presents modeling and validation of Gatimaan Express, a superfast train which will be running from New Delhi to Agra Cantonment at the speed of 160 kmph and will cover 205 km in 105 minutes. It will have 12 air conditioned coaches with one locomotive class WAP5. In the current study, mathematical model with one locomotive classWAP5, one generator van, one second class chair car and one executive chair car is presented in this paper. The overall 152 (4 × 38) degree of freedom model is developed in Matlab/Simulink. The vertical and lateral track irregularities are the inputs to the system, based on ORE B176 standard with high rail irregularities. Research Designs and Standards Organisation (RDSO) provided data pertaining to the track geometry and velocity measurements as well as actual run data of lateral and vertical accelerations of locomotive WAP5, generator van, second class chair car and executive chair car. The vertical and lateral accelerations of locomotive, generator van, second class chair car and executive chair car of Gatimaan Express model are compared with the available measured sample data.
