Can someone explain to me why this should be routed through Peterborough instead of building a dedicated line along the lakeshore?
The population differences between the two are massive.
It has to do with rail ownership.
CN and CP own the two rail lines along the lakeshore. They are two of some of the largest companies in Canada. They hold a huge amount of political clout.
Both do not want passenger rail or electrification anywhere near their lines. They allow VIA on their lines now, but as an afterthought.
In the 2000's an attempt was made to work with CN to add passing tracks etc in their corridors for VIA to pass their slow freight on. Not only did CN overcharge VIA for the work, but they made the agreement as such that they can use the passing tracks for their freight as well. Guess what happened, they did exactly that and we spent millions of taxpayer dollars to give CN new tracks for their freight. Passenger rail meanwhile got worse.
Thats the problem, all work in the lakeshore corridors, to even add tracks for dedicated rail, have to be done by CN or CP if its in their corridors. You can forget about electrification too.
The government buying up CN or CP is an unaffordable acquisition. To build their own rail lines in the lakeshore area would require massive land expropriation and would again be way too expensive and have NIMBY backlash out the wazoo.
The only feasible option in our current political climate is to buy up disused and rarely used rail lines in the north, upgrade them to Class 6 rail and electrify them.
And honestly, its not so bad. Other than the fact that there are some curve issues we have to deal with, it means we dont have to deal with CN/CP, and this train service is supposed to be an express service between major cities. Its not meant to be a milk run to service all the small towns along the way. Leave that up to the existing train service along Lakeshore. Besides, Having two services is better than one. As well, this train route is more direct to Ottawa, which is a huge destination in its own right, moreso than Kingston or other other smaller towns along Lakeshore.
