Monorail

The Gotham City monorail was built by Thomas Wayne and Lucious Fox. Some of it was destroyed during what was perceived as a terrorist attack on Gotham. But the system still remains in Gotham City as a cheap way of transportation around the city.

Thomas Wayne spent the better part of 7 years studying at Hollywood Upstairs Monorail School, learning the ins and outs of the monorail trade. He was sadly two days away from graduating with honors when he was killed.
