If not you can use a invisible station...It may take a while to work it out but it's very beneficial. Also search FMA UK Platform on the dls if you want the platforms used by subsurface stock trains like C, D, and A. I'm also assuming you have all the LU stock available now, but if you don't they are C and D stock, 1938, 1967, and, although its not passenger enabled 1996. Let me know if this is any help.
