^The whole plan does smell of political pandering and I am not a fan of that. But what else is new in the world of politics?
This is one of those cases where instead of smashing the idea in hopes that it can all be rewritten from the beginning, why not make the most of it? Consider this. There are 3 groups who currently have an interest in rail investments. One in Ottawa where the idea of commuter rail to Smiths Falls is being explored. Another with CP Rail looking to increase freight capacity between Smiths Falls and Peterborough. And of course the GTA which wants to develop commuter services between Peterborough and Toronto.
Why not develop a plan that works for all these groups and turn the project into an upgrade of rail service from Toronto to Ottawa via Peterborough, Havelock, Perth, Smiths Falls, Carleton Place and onto Ottawa with a few more commuter stations in the two major centers. You can electrify the urban portions, ensure that freight upgrades also allow for passenger rail considerations, and also throw in a new long distance line from Ottawa to Toronto that will serve smaller, but mostly new markets and communities.
If the goal of rail/transit advocates is to really improve service and add new markets then there needs to be less soap box preaching and single track (no pun intended) visions, and more playing the political game and being willing to think a little differently.
