By accelerating the overcoming of space on certain relations, transport systems distort geographical
time-space and alter the accessibility of places. Particularly in the case of discontinuous and tiered
transport systems such as the (high-speed) rail network, effects on time-space can be highly selective
and difficult to visualise. This paper compares different methods of operationalisation and visuali-
sation of the effects of new transport systems, i.e. infrastructures and services on time-space, and
examines their strengths and weaknesses, using the example of the evolution of the German rail net-
work between 1990 and 2030.
We seek to contrast ‘chloropleth’, ‘anamorphosis’, ‘spring’ and ‘shriveling’ maps, generated by using different measures from network theory, according to five properties of geographical time-space, adapted from L’Hostis and Abdou (2021). These are a) the acceleration that causes shrinking of a geographical time-space after introducing faster transport means, which allows for comparing different states of time of the network; b) whether transport networks can conveniently be drawn on cartographic representations; c) how well various transport modes can co-exist on a map; d) how to deal with spatial inversion caused by extreme forms of detour, where a journey starts in a direction opposite to the end destination; and finally e) the theoretical assessment of the overall legibility and interpretability of the visualisation.
