Italian to English translations [PRO] Tech/Engineering - Manufacturing
Italian term or phrase:porta a doppia volata
From a tech spec for internal train doors. Please read both contexts:
1. Porte a doppia volata ad apertura manuale e chiusura con dispositivo di richiamo
2. La porta sottoposta a n. 3x10^5 cicli di apertura/chiusura (nei due sensi per quelle a doppia volata) non deve manifestare anomalie
The first context makes me think, OK, a normal leaf door. But the second context makes me think more of the swinging door one finds in hospitals, i.e. that opens in both directions. I've been on a lot of trains in my life and I've never seen an internal train door like that.
