It's pretty hard to counter an idea that comes out of the blue with little to no known details other than a suggestion of 'why don't they do [x]'. One sides view that something is not feasible/too expensive/just plain dumb/etc. is just as valid as the other side's 'no it's not' or 'prove me wrong'.
Any and all future ideas could be feasible, and could be worth the cost, but most people only look 5-10 years down the line.
I vote for a transit mall to be included in the rebuilding of the Centre Block, and that there be a dedicated line from Rockcliffe Park with a stop at Rideau Hall and 24 Sussex. So there.
What is the reasoning to do that? What current or future need would it fill?
How many VIA trips go through Montreal? If HFR is built, how many trips will go through Ottawa?
If you look at pre covid times, there are 5 trains each way a day that pass through Montreal between Ottawa and Quebec City.Pre covid, there were 10 trains each way between Toronto and Ottawa that terminated or started in Ottawa. To me, that sounds like if they served the downtown Union station in Ottawa and terminated or started from there, it might make sense.
Remember that Ottawa is a car-focused city, much more than Montreal is (or we are). The Tremblay location is, in reality, much better for Ottawa's population.
And at$2 a litre, there are conversations about giving up the car. I am willing to be that a shift from owning more than 1 car per household will happen in the next 5-10 years. That means that a large station devoid of housing, and no easy connection to the station isn't so appealing. If the government will let Via take up the slack that many are looking at, we could see a renaissance in rail travel.
I say that there are few generators. You say that there's been no change since the 1980s, which could be sunk cost fallacy, or an argument that there are enough trip generators. But given your history, I'm leaning towards the former.
Actually, I was trying to point out the reverse - that since the 1980s, the trip generators have increased, and it would be foolish to ignore that increase.
I'm not saying it's impossible, but what would be the increased costs of summertime drainage? Political pushback? (The canal being UNESCO and all)
You bring up very interesting points.
Summertime drainage- can be mitigated.
Political push back -Doing this kind of project would need to be seen as it would be political suicide if it was not done. In that case, the push back would be lower. You will always have push back, but that does not mean we should do nothing.
UNESCO - If the canal and grounds around it remain as it was, but the road was ripped up to get the train lines down to the station, I don't think it would lose its designation.
You're the one proposing a Union Station. You need to show us why it's a good idea, which I don't see.
Some people will never see things as good, and that is ok with me.
Which are better value than a Union Station ... it's always about the cost/benefit ratio.
Did I suggest it to be the next big thing?
Nope. Like I said, I doubt if it is on anyone's radar, and that is good as it is not anywhere near a priority.
