First of all, with its current route, Brightline competes more with Tri-Rail, than it does with Amtrack. In 2019,
Tri-Rail had 4.5 million riders. In the same time period,
Brightline had 885 thousand riders.
Secondly, while Florida East Coast Industries (FECI) is willing to subsidize Brightline while they are making money on real-estate, once that revenue dries up, will they let it die?
Thirdly, bringing it back to Canada, what corridor is there here that a developer (like FECI) would be willing to subsidize a new rail service to boost their own real-estate development? They need an underutilized rail corridor in the urban area at a minimum. The proposed Calgary-Banff train might be under this model (not sure), but even that is far from being a done deal. IIRC, they only want to operate it for 30 years and then have the province take over operations, which certainly smells of developer wanting to build it to make money in the short term without the long-term responsibility.
