Attribute
Private boolean
  isIntentionallyDarkAllowed
Details:
Notes: The line-side system can switch the light signal to intentionally dark when a cab signalling ATP system such as LZB or ETCS is leading. <br/>The signal lamps are intentionally turned off and the driver disregards the light signal.<br/>This avoids conflict between line-side aspect and cab aspect in dual signalling environments.<br/><br/>Not to be used when a signal is switched to a special aspect (white lamp or white cross), indicating that the signal should be disregarded. The other signal lamps are dark but this is not meant by intentionally dark.<br/><br/>Notes on dark signals:<br/><ul>
<li>A light signal that is dark because it has failed represents danger.</li><li>In the UK, dark mode applies to LX warning light that switch to dark on purpose, e.g. a failed level crossing in the UK because a permanent warning light invites undesirable behaviour by motorists.</li></ul><p/>
Private boolean
  isTunnelSignal
Details:
Notes: Signal placed in tunnels, typically used to indicate special fixing requirements and/or light intensity.<br/>
