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 of reason

would cause the stopping of all the trains running in its jurisdiction

area. This memoir intends to propose an analytical

evaluation of the improvement in the RAM parameters

of the concentrated ETCS trackside subsystem (Radio

Block Center) achieved with the introduction of a backup

apparatus. It is even hereby presented a personal interpretation

of the “minor failure” according to the specifications

in references [1] and [3]. This back-up RBC has even

represented a temporary solution for the verification of

the line sections Novara-Milano and Gricignano-Napoli

leading RFI to use the “Mirror” system configuration for

the tests preceding the final activation.
