It was considered Cleveland's ghost train. The RTA Waterfront Line -- once shut down - - was reopened in hopes of riders flocking to the new Flats district. But six months and $375,000 later, those trains remain relatively empty.

To get to her job at Lago in the flats, Maria Maniccia takes a bus, then transfers to the Waterfront line.

"It's very rare that people are on there. Probably around, in the mornings, there's definitely less than 10," says Maniccia.

We spent 2 hours on the Waterfront line. At night, we saw no riders at all. In the morning rush, we counted only four riders.

"Once you get to Tower City, it picks up, but coming from this way, no," says Jason Jackson, who is headed a few stops west from the Flats.

Even in the middle of the day, we watched as Jackson, an RTA regular, climbed onto the train as the only passenger.

"It's so new again, a lot of people still think it's shut down. We're still getting the message out," says Mary Shaffer, RTA spokeswoman.

Low ridership is what shut down the waterfront line back in 2010, but Shaffer says at this point there's no reason to consider cutting service.

"What we're seeing now is as we head into the winter, more and more people start taking the trains, so we're hoping we can attract even more riders," says Shaffer.

The hope was Ernst and Young employees as well as Aloft hotel guests would bring packed trains, but the redevelopment of the Flats isn't complete.

The RTA doesn't track ridership numbers for the Waterfront Line specifically because it's part of the Blue and Green lines, but the numbers for those show an increase of 5 percent.
