ORLANDO, Fla. — SunRail has broken its own passenger record, when this year's 1.5-millionth passenger boarded a train Thursday.

• As SunRail ridership grows, more routes could be added
• In 5 years, SunRail has grown to serve 4 counties

The milestone marks the most passengers the rail company has had in a calendar year. 

As ridership grows, more routes could be added. For months, there have been talks of Virgin Trains linking with SunRail, offering connections at Orlando International Airport and Meadow Woods and a plan to expand hyperlocal service to seven days a week.

Back in May, SunRail rolled out a $200,000 mobile app to help people manage their trips on the go.

In five years, SunRail has grown to serve four counties.

The Florida Department of Transportation is in charge of funding and operating SunRail until May 2021, at which point the municipalities SunRail serves will have to foot the bill.
