Double line automatic signalling : ウィキペディア英語版 | Double line automatic signalling
Double Line Automatic Signalling is a form of railway signalling used on the majority of double line sections in New Zealand. Double Line Automatic Signalling uses track circuits to detect the presence of trains in sections broken up by intermediate signals. Usually there is an 'up' and a 'down' main line, and beyond station limits the lines are not bi-directionally signalled. DLAS is not designed for wrong-line running in emergency situations.〔(Report 08-110 train control operating irregularity leading to potential low-speed, head-on collision Amokura 23 September 2008 )〕 ==Junctions or points== At junctions or points, one of or both mains signals are usually controlled either remotely (by a Train Controller or Signalmen) or switched in at a local panel.
