In German, even the spelling of the Neanderthal man (whose fossils were first found in the area) has been updated to Neandertaler from the outdated Neanderthaler.

The nearby Neanderthal Museum and the municipality of Mettmann have adopted the policy that all names referring to the prehistoric humans have the "h", so they in fact use the spelling Neanderthaler for the species, which is not done anywhere else anymore in German-speaking areas, but even they do not spell the valley in the outdated way anymore (except seemingly in the name of the museum, which is in fact English, not German).

The municipality claims that the German rail authority would not change the spelling because of the proximity of the museum.

The history of the railway was considered in the design of the gardens and parks around the station and the grounds are filled with old artifacts of the railway history along the course of old Nordbahn as well as hundreds of species of bamboo and elaborately designed wall coatings and ground coverings.
