Fröndenberg station

Fröndenberg station is a wedge-shaped junction in the south of Fröndenberg near the Ruhr river, where the Fröndenberg–Unna and Letmathe–Fröndenberg lines converge with the Obere Ruhrtalbahn. The distinctive wedge (Keil) track layout, where two lines meet at an acute angle, is its only notable characteristic — otherwise a functional regional stop with no documented cultural or historical significance.
