People walking near Google's Chicago headquarters in Fulton Market have noticed a CTA train car atop the building this month.
The decommissioned train car was installed on the roof of the 1K Fulton Building in March, a project that is expected to be completed by the end of May, a Google spokeswoman told DNA Info.
When complete, the train car will serve as a place to sit on the green rooftop for employees. The deck will also have raised a platform with views of the Chicago skyline!
Here's the video of the "L" train being lifted onto the roof.
