So a 17-18 minute travel time to West Harbour? That's pretty brutal. I thought I remembered it being planned to be more like 8-9 minutes. That's an average speed of like 30km/h between the stations!
That also means there is a 34-minute travel time from Confederation to Burlington GO station.. that only takes ~10 minutes to drive between (maybe 15-20 minutes in rush hour).
No wonder they only built 100 parking spaces.. nobody will be using it. If I lived in Stoney Creek would just keep driving to Burlington GO which has far higher service levels and is far faster, even with bad traffic on the skyway.
Hamilton Centre GO is limited by the tunnel. Ironically the tunnel is actually built for two tracks - but has a curved ceiling which means it can't accommodate modern train heights with a 2-track configuration. I often wonder how much it would cost Metrolinx to "square off" the tunnel and enable a dedicated GO track into the station to enable regular all-day service to Hamilton Centre. It's certainly a far more centrally located and more useful station for the city.
The tunnel is less than 600 metres long - they could probably just close Hunter St for a year or two to dig it up, fix it, and rebuild the street.
