If they ran with just one locomotive, they wouldn't be able to run 125 mph on the brand new tracks to Orlando. They would be limited to 110 mph with single locomotive operations.

Per EMD, it requires 4530.5 BHP to sustain a max speed of 125 mph. The SC44 is only rated at 4400 BHP. Although the Siemens SC44 locomotive can achieve 125 MPH, but only while operating downhill.
Additionally, the alternator is rated at 4400 HP short term, 4200 HP continuous, and at the wheels it is rated at 2900 HP to 4000 HP depending upon HEP.
I would also like to suggest the routing of the Brightline corridor between Orlando and the Cape is not downhill in either direction.
FYI: I'll admit I don't have the technical expertise to agree or disagree with EMD, but I am willing to give their engineering experience some faith, although they did have some conflict of interest with an opposing locomotive.
