Pretty circuitous route South of Brampton to the Streetsville GO station....not sure why someone with a final destination of Union (if this ever happened) would ever consider not getting off at Brampton and going to Union from there (assuming any service in this hypothetical line had its schedule co-ordinated with the the schedules on the KW line through Brampton).If it was a separate service than GO, yes, as I don't think Metrolinx/CP wants anymore trains on the Milton Line, or going to Union.
Ideal would be to go to Milton line and express to Union, but thats a pipe dream.
