ABSTRACT
The drawing and application of train diagram has a great significance on enhancing circuit efficiency in urban rail transit system. In the construction of domestic urban rail transit, facilities of signaling system are mostly manufactured by foreign companies. It leads to lots of inconvenience and high costs in project fields such as facilities installation, commissioning, fault detection, and integration with other software systems. Therefore, the localization of urban rail transit signaling system will make a great help in domestic urban rail transit construction, and the diagram part is an important component of ATS in signaling system. Based on train traction calculation, this research is aimed to develop a train diagram drawing tool with convenient maneuverability and good portability.
