In a first step, the development from the by-product of the coal industry, which pollutes rivers, to the coveted wood impregnation agent for railway sleepers is to be reconstructed. If one then follows the creosote from the waste material to its new application as an impregnating material, a promising view on historical maintenance cultures opens up, which in large parts still has to be regarded as a research desideratum. The analysis is primarily aimed at the workers: inside the impregnation plants as well as the permanent way inspectors, platelayers, and track walkers in the railway maintenance service.

Impregnation institutes play a central role in the landfill registers that were created in the 1980s. The reconstruction of the conflicts surrounding their rehabilitation, which has been reflected in a growing number of citizens' initiatives in recent years, is a fruitful topic for interdisciplinary research at the interface between environmental history, the history of technology, and environmental sciences.

Finally, the history of the railway sleepers is also rich in changing forms of conversion, which should be examined in detail. In the railway foreman's creative use of old sleepers, the line between maintenance and innovation seems to be blurring. Until they were classified as a hazardous substance in the 1990s, impregnated old sleepers also found their way into public spaces and private households, where they were used, for example, as fence posts or raised plant beds.
