Train traction calculation is an important part of urban rail transit system.

The software system for locomotive traction running is designed and developed based on longitudinal profiles of running lines and performance data of locomotives, rolling stocks and their group, by use of object-oriented technology of visual c++, in combination with train traction calculation, train running analysis, locomotive circuit simulation and so on.

According to the characteristics of train traction calculation, we firstly obtain the haul force of locomotive at any velocity point using Lagrange formula, and then solve train motion eqution in the light of distance interval by approximative integral method.

It was presented a computer simulation study of train traction calculation, addressed the application of computer simulation procedures detailed calculations, and the need for the establishment and im.
