I believe that the Sheppard Subway plan had the GO station being moved south of Sheppard. I see the an elevated Sheppard line having an elevated station on top of the GO station - actually, just East of it. I think I left about 125m to drop 6m to go under the CP line just after the Agincourt station.
The idea was that it would be built where the CP line crosses the GO Stouffville line, creating a potential three-way transfer point with TTC subway, GO Stouffville, and GO Seaton/Havelock lines.
It would more closely follow the path of the creek, rather than having a 90 degree turn.
