Does anyone know anything about these? Looking at their website, the low current draw (70mA) suggests that it might be one that proves it is functioning to the signal box by relay closures.

So far I have...

Here there are some shots of the frame from John Tilly's incredible site. http://tillyweb.biz/gallery/qq/quorn.htm which show the frame and the diagram, where the levers 5 and 25 (the B&W ones) are next to two lines perpendicular to the line on the Up and Down Mains.]]> 16 Sat, 16 Sep 2017 08:28:47 +0000 https://www.national-preservation.com/threads/signal-box-electricity-supplies.1005176/ https://www.national-preservation.com/threads/signal-box-electricity-supplies.1005176/ invalid@example.com (johnofwessex) johnofwessex
In Rural areas there was no mains power until after WW2 and Adrian Vaughan describes mains power being laid on to his box in the mid 1960's

So how was electricity provided, especially as more electrical/electronic systems were added and power operated signals and points, in particular Intermediate Block Sections prior to the provision of mains power]]> 9 Fri, 15 Sep 2017 16:31:18 +0000 https://www.national-preservation.com/threads/signalling-bells-query.1004029/ https://www.national-preservation.com/threads/signalling-bells-query.1004029/ invalid@example.com (Steam Yak) Steam Yak I have a friend who has a pair bells from a,signal box, he asked me what voltage thee work on.

groundsignals as route indicators.]]> 18 Thu, 05 Aug 2010 19:18:25 +0000 https://www.national-preservation.com/threads/williton-advance-starter.26110/ https://www.national-preservation.com/threads/williton-advance-starter.26110/ invalid@example.com (southyorkshireman) southyorkshireman here

At the Blue Anchor end of the line the advance starter (labelled 20) is apparently the wrong side of the sole home signal.... Is 21 actually the section signal and 20 only used for controlling run round movements (as a limit of shunt?) to return trains that terminated from the Blue Anchor direction?

Confused, on...

Are there any issues with the train apparently splitting on the signalling diagram when the banker drops off?

By methods I mean not just block working but pilot, etc. Or if anyone can outline the differnet methods here than I'd be very grateful!
