Abstract

E' descritto un apparato di protezione del treno, particolarmente per linee tranviarie e metropolitane, che prevede il rientro automatico in esercizio ATP dopo una marcia in permissivo dovuta ad assenza di segnali ATP. Se un treno (Z) frenato con frenatura di soccorso in seguito ad assenza di segnali ATP per un guasto ATP di terra e poi fatto procedere in "permissivo" riceve nuovamente i segnali ATP, questi vengono accettati ed utilizzati a bordo per la protezione del treno solo dopo che il treno ha percorso in "permissivo" uno spazio minimo predeterminato e nel frattempo ha ricevuto in continuazione i segnali ATP. In questo modo viene impedito che il treno riacceleri troppo presto in conseguenza di difetti non riconosciuti nella segnalazione di "libero" (Figura 1).A train protection apparatus is described, particularly for tramway and underground lines, which provides for the automatic return to ATP operation after a permissive march due to the absence of ATP signals. If a train (Z) braked with emergency braking following the absence of ATP signals for an ATP ground fault and then made to proceed in "permissive" mode receives the ATP signals again, these are accepted and used on board for the protection of the train only after the train has "permissive" traveled a predetermined minimum space and in the meantime continuously received ATP signals. This prevents the train from accelerating too early as a result of unrecognized defects in the "free" signal (Figure 1).
