A very warm welcome to the forum!
I'm curious as to why you ask such a question? Is it for someone with a disability?
I presume there must be an official website for the Beijing rail service, with a customer services section who could help and advise you.
I believe we do have one or two Chinese members here. They might have first hand knowledge of the lines.
