The completion of this project opened up possible extensions of the network further west and south into Nepal and to Yadong County , close to the border with Sikkim , India . Although there were plans to extend the line with another 700 km to the Chinese border with Nepal , those plans became delayed due to difficulties on the Nepal side after the April 2015 Nepal earthquake . Feasibility studies were proposed for extension towards Zhangmu , although another border crossing may be chosen due to major Nepali abandonment of the border post
