With the growing of subways, the requirements for managing subway trackside equipment are also increasing. BIM Technology with its information, intelligent characteristics, can be widely used in the project life cycle management. However, when modeling, the commonly used modeling software, Revit, has great limitations in batch creating models and inputting parameter information. Dynamo technology is used to obtain the location information of the equipment in the subway line, and the automatic placement of the equipment is realized according to the location information. Then the corresponding relationship between the engineering information and the equipment is established, and the parameter information is filled in batch. The research results show that: during modeling, the tedious and mechanical work is automatically completed by visual programming language, which can greatly improve the precision and efficiency of modeling, and lay the foundation for the realization of the whole life cycle management of Metro Line trackside equipment.
