Northern line signals
In article ,
y wrote: Just wondering why all the signals are bagged on the northern. I realise its now running ATO but why not just disconnect the old signals entirely so they're off? I expect that is because a signal that is bagged is clearly decommisioned (or not yet commisioned), but a signal that is unlit is required to be treated as a red signal - becuase that's the safe thing to do if the bulb blows. -- Mike Bristow |
