Dia.Man.Te (an acronym for Diagnostica e Manutenzione Tecnologica – Technological Diagnostics and Maintenance) is the new diagnostic train operating for Rete Ferroviaria Italiana (Gruppo FS – Italian Rail Network), specifically designed to work on high-speed lines.
The latest model in a long line diagnostic trains, the Dia.Man.Te. is the first rolling stock in the world capable of measuring the state of rail infrastructure while travelling at 300 km/h.
Moment by moment the diagnostic train checks 200 parameters relative to:
superstructure (track and ballast),
power supply (overhead line),
signalling (ERTMS – European Railway Traffic Management System),
telecommunications (GSM-R radio system).
The diagnostic systems installed on board the Dia.Man.Te. are the result of made-in-Italy innovation. The concept and operational design are all the work of RFI (Rete Ferroviaria Italiana).
THE FLEET OF DIAGNOSTIC TRAINS
Archimede, in service since 2003, is an extraordinary and innovative concentrated package of technology capable of continuously measuring 119 different parameters which, when integrated with one another, make it possible to check the state of the railway infrastructure in real time.
The diagnostic train for track measurement, the Galileo, has been in service since 1997, using ultrasound and digital video-inspection technology to check the state of the rails.
Talete, on the other hand is dedicated to inspecting track geometry, accelerations and wear of the rails. It measures all the alignment and rail level values using laser optical triangulation and gyroscopes.
Caronte is the motor train unit dedicated to diagnostic operations on lines equipped with SCMT (Sistema Controllo Marcia Treni—Train Running Control System) and SSC (Sistema Supporto Condotta—Driver Support System). Furthermore it is the first rolling stock in the world which certifies signalling in accordance with European standards.
Euclide brings together all the characteristics of the three trains described above, using optical laser technology. In particular it is used to measure the undulatory wear of the rails.
Aldebaran on the other hand is specifically designed for mobile diagnostics of the electrical systems. This is a special carriage which was the first ever to use laser technology for measuring all the parameters for overhead lines and the interaction between the pantograph and the power cables.
Fifteen traction units fitted with special equipment for detecting track geometry and a series of portable trolleys used to check the geometric parameters of switches complete the fleet.
