Your turning radius is more than 4x greater, necessitating more tunnels and viaducts. The tunnel entrances have to be designed differently to deal with the boom effect, etc
The high-speed rail component in Project Nexus is only for the Canadian portion of the line and does not include the portion built south of the border....

Right, and that's why I'm using
the GO expansion - regular heavy rail - as the benchmark instead. $13.5 billion over 150 km gives me $90m/km; with 350 km, that's $31.5 billion, or almost 3x the lowball estimate.
