An experimental test campaign has been carried out on the track equipment system for "50 UNI" rails with reinforced concrete precast formation laid down on elastomeric mattress. This system will be utilised for the preparation of the Bari-S. Paolo underground railway superstructure. Some experimental test have been carried out on prototypes in order to verify the performances of the proposed system. The paper illustrates the results of the tests and gives some design directives deriving from the analysis of the experimental tests.
