U5 (Frankfurt U Bahn)

The U5 is a line on the Frankfurt U-Bahn. At the time of the line's inauguration in 1974, it ran from the central railway station to the Konstablerwache and then continued along the Eckenheimer Landstrasse all the way up to Preungesheim. After Konstablerwache the line is running above the ground towards Preungesheim. Until 2016 PTB cars were used as there were street level stations. In late 2016 two stations were retrofitted with high-level platforms, and the other two closed, letting the high floor U5 class operate.
