GO expansion with electrification, is talking about raising average speeds to 60 kph. Milton Line has pretty wide stop spacings, including essentially running express from Kipling, so perhaps even higher average speed would be possible, or at least many more infill stations could be added while maintaining current average speed (around 60 kph now). I could imagine an express service (with fare integration) from Kipling to Union that only took 10 -12 minutes (down from 20 currently) being pretty popular.The idea of converting the Milton Line to something else and making a diversion is really interesting. I wonder how well it could meet the needs of those commuting from Lisgar or Milton…. that’s a long ride.
