When new motorized means of transport, such as buses, vans, and lorries, captured part of the transport market in Belgium in the interwar period, the rail companies engaged in a political fight to restrict the new modes of road transport. Attempts were made to introduce fiscal and administrative measures aimed at limiting road transport. This coincided with an intense debate on transport policy, both in the press and in parliament. The article focuses on the discourse driving this debate. It is argued that the positions taken were motivated by economic issues, but that there were underlying cultural motivations, different perceptions of what transport should represent in the lives of the users and the whole of society. The focus on the so-called coordination debate is widened beyond the conflict between trains and vans in the 1930s, to include the conflict between automobiles, buses, and trams in the 1920s.
