I think that we need a Brightline Route in train sim world 4. The trains would be the SCB-40 with Venture coaches, and the Florida East Coast GE ES44C4 with the natural gas tank. You would run the Brightline train from Miami to Aventura, Fort Lauderdale, Boca Raton and West Palm Beach. You could also run the Florida East Coast freight train from Miami to West Palm Beach. Or starting or ending at various locations.
Extend to Orlando and include a GP40-2/-3 for local and switching operations. FEC runs rock and intermodal trains mostly, but also handles other types of freight. DLCs could include FEC SD40-2s and GP38-2s.
