Re: Electrically operated semaphore
not down here, I don't think so.
Re: Electrically operated semaphore
I was meaning to put it up ages ago, I actually put it up for the "Twilight" effect since we don't know how long semaphores will be around :(

Re: Electrically operated semaphore
Hi
When I was involved with the lengthening of Muldersvlei up platfporm and loop the Home (Junction) signals and the outer home and distant where electrically controlled by the signabox levers. They were still repeted by the 2 volt repeaters in the signal box. Release or disengagemnt of the signals was done by track circuit also dsplaying on the box diagram 1962 (I think)

Thanks Chris
Do you perhaps have a picture of the old diagram from there??
Northdene is the same with a track circuit.

Re: Electrically operated semaphore
I seem to recall seeing electrically operated semaphores at Noupoort many years ago. Also have a recollection that wire-operated signals become problematic after 2 200ft (670m), or was that the distance after which signals had to be operated by double-wire?? Any signal construction experts out there?
