Which makes you even more off-base.
The majority of the 1.2 billion spend is on upgrades to the corridor itself, upgrades that will benefit any form of rail service the line will see and this line is posed to see a huge increase one way or another. Only a small portion of that is going to items exclusive to the UPX such as the 128 million expense for the 3km elevated viaduct to the airport and the cost of 3 specialized station platforms at Union, Weston and the Airport. The equipment itself could be re-used or sold off. And I'd imagine that the $100 million they mention for service development business and operations planning is mostly allocated to hiring, training and maintaining a larger work force, all of which can be differed to expanded service in other corridors if need be. Hence if it were to fail, there will be some waste but any comparison to Mirabel is ludicrous, they're not even in the same league yet alone same ballpark.
