Ram analysis of the Radio Block Center System for Italian ERTMS lines
2010
Num. 4
  The ETCS technology-based train spacing system adopted in the Italian HS/HC railway lines is a key element both for safety and regularity of train running. Its failure as a consequence of any kind... read all
A methodology for correlating the quality of the pantograph-catenary contact with the harmonic content of the current collected. A case of multiple current collection
2010
Num. 3
  It is a well known fact that when the catenary supply system is mechanically disturbed, electric arcs may develop on contact between the catenary and the pantograph. The variation in supply voltage... read all
