It has been an eyesore for years - the old Detroit train station.
Billionaire Manuel "Matty" Moroun is making improvements, with more than 1,000 new windows getting installed.
Most people look at the train station from the outside, today FOX 2 got a look from the inside.
"I think it's gorgeous, the architecture is just fantastic," said Gary Chamberlain, one of the workers. "We are just so happy to be a part of it."
And as part of a deal the Moroun family, who bought the station in 1995, made with the city.
About 1,080 windows are being installed on 15 floors.
"These windows weigh about 350 pounds; they are architectural grade windows that go through the most stringent testing,” said Ken Carter, project superintendent.
And the test will be to reinstate, at least the windows, back to the building of 1913.
"It was bustling," said worker Harry Meeks. "There were people moving around everywhere."
This structure closed in 1988. In the south concourse, where you enter to get to the trains, are 54 foot tall ceilings that used to showcase 20 large skylights and ornate wooden benches, from 1913.
The project should be completed by the end of the year. There are no other plans to fix the walls or the floors but some work will be done to the roof as well.
