All Aboard Florida has delayed the startup of its Brightline passenger train service.

The Brightline service had been scheduled to start between Fort Lauderdale and West Palm Beach in August and to include service to Miami in September.

All Aboard Florida now expects to hold a grand opening for its Brightline rail service sometime in fall.

The service is expected to extend from South Florida to Orlando by 2019.

Construction work at the Brightline train stations in Fort Lauderdale and West Palm Beach is nearly finished. The larger station in Miami will take longer to finish.

All Aboard Florida officials declined to cite station construction or any other reason for the delayed startup of the Brightline service.

The company has encountered a delay in the delivery of its fifth train for the Brightline service. The train, which was supposed to arrive in West Palm Beach this week, is still being finished at a manufacturing plant in Sacramento, California.
