Compared with architecture engineering

the design of railway BIM is unique for its features

such as multi specialties

complex interface and closer relation with topography and geology. Presently

because the BIM resources cannot be utilized well among specialties

the railway engineering BIM is still based on single specialty model

which makes it difficult to carry out forward design of all specialties. In this case

Yinchuan-Xi’an High Speed Railway project is taken as the pilot. Based on Bentley platform software

this paper conducts research on railway engineering BIM forward design according to the general design process of railway engineering. Finally

the method of railway BIM collaborative management and forward design is put forward and railway BIM standards are preliminarily applied

which may provide references for future BIM design of all railway specialties.
