ya actually lakeshore east has a few grade crossings still, (scarborough golf club road and i wanna say mccowan?) but afaik they are all being changed to segregated crossings as part of the early works. That info might be incorrect too as i know mx has done some weird things moving stuff around with the off-corridor and early works projects
safe to say that by the completion of Go expansion LSE should be all grade separated.
LSW on the other hand, is weird in that as far as i can tell only 2 of the 10 railway crossings that exist up to bronte are being upgraded (kerr and burloak)
There are a few smaller ones, but at this point we should be removing every single one anyway
