Do you have a map like this showing Barrie and Stouffville with what double tracking they have as of today? im curious where progress has been left with those projects.
Here you go.
The only operable double/passing track segments in operation are in green. Blue is areas where there is active track building in progress. You will note that there isn't a lot of passing capacity as yet. 2-way service is limited to hourly by what's there today. The Stouffville line is pretty close to having more capacity (although the leg from Kennedy to Union is problemmatic, thanks to construction). Barrie is just getting going.
