Until the early 1950s, the Ascot Park and Oaklands stations serviced Marion with a single rail track.
This ensured that the footbridge provided the sole personal access to both the platform and to the other side of the line.
At the northern end, a more convenient low-level track crossing and station access was re-installed in the 1990s.
As part of the electrification of the line, Marion station was rebuilt in 2013, with a new waiting shelter installed, an underpass built and the bridge demolished.
[7][8][9] Local residents had expressed their preference that the overpass be replaced instead, based largely on undesirable behaviour that occurs in an underpass because of the lack of visibility.
