More political problems caused by the stock market crash of 1929 stalled the project further to the point where the idea of a rapid transport system was abandoned and the project began being referred to as “Cincinnati’s White Elephant”.
In 1936, the city commissioned the ‘Engineer’s Club Of Cincinnati’ to produce a report on the viability of the system and report on what, if anything could be done to re-start the project. However, the report stated that as the cities needs had changed in the 20 years since the project was first started and recommended that it ‘should be forgotten’.
In 1939 the City looked at using the tunnels for automobile traffic, but it was found that they were unsuitable as they were too narrow. It was even argued that the cities street car traffic be sent under ground using the tunnels but before this option could be properly explored, the financial burden of WW2 once again stalled the subway project.
During the war, even though there were many plans to include the redundant subway system in the cities war effort, including mass air raid shelters or hidden munition path ways, none were ever implemented and once again the subway remained desolate and abandoned.
