Next stop- Kasbachtalbahn.
This steeply graded line is operated by the classic German Uerdinger railbuses as a tourist line from Linz to Kalenborn.

The Kasbachtalbahn is a non-electrified single-track railway which originally linked Linz (Rhine) with Flammersfeld. Only the section between Linz and Kalenborn remains open runing in the valley of the Kasbach river. The railway line is one of the steepest routes in Germany, the largest gradient is 5.7% and the difference in height between Linz on the Rhine and Kalenborn is about 300 m.
Since 1999 the 8.9 km between Linz on the Rhine and Kalenborn has been operated as a tourist railway with Uerdinger railbusses.

Uerdinger Rail Bus is the colloquial designation for railbusses developed by the Waggonfabrik Uerdingen. These are diesel powered two-axle light rail vehicles with diesel engines installed underneath the car. These were used in the passenger train service on routes which are not profitable for steam locomotives or diesel trains. From 1950 to 1971 1492 were built, including all trailer coaches and vans the total number of units produced is 3306 cars. Most of these vehicles were manufactured by Waggonfabrik Uerdingen itself.
The motor cars were called Rote Brummer from the driving and engine noises.
