Abstract

The paper deals with the development of the mobile diagnostic computerised systems adopted by the Italian State Railways (Ferrovie dello Stato = FS) for the automatic monitoring of contact lines and the relevant expected performances. In particular it refers to a new system providing the main geometrical data of the catenary, by using a special motor trolley, which performs continuous measurements while running. A great importance is given to the innovative measurement system of the residual thickness of the contact wires, which is able to check more than four conductors at the same time. The common employ of this new trolley and relevant computerized system in Italian railway electrified lines will produce a great improvement in the planning of catenaries maintenance and management.
