Signaling questions? He hasn't even finished the baseboards yet!

Progress on the baseboards continues at a pace with the ply framing now constructed for two boards and mostly complete for the third. So far I'm rather pleased with how it looks.

from the railway room door things begin to take shape. The templot plan is laid down and the two large mill buildings fit nicely.

Underneath the layout the ply frame is nice and stiff and fitted with lots of useful holes to feed wires through.

Looking across the workbench and you see the area planned for the river and bridge.

 

So, what is all this about signaling and why ask questions now?

 

Well the plan is to sit the lever frame in the front of the layout but I want to recess it into the baseboard so it doesn't sit too high and also make it removable so that the whole frame can be removed from view when I want a clear shot for photographs of passing trains. The original frame from the Scalefour Society has 20 levers but with the change in track plan for the new layout I suspect I'm going to need to extend it. This impacts the baseboards because I need to work out just what size hole to cut!

Thanks to advice from the signaling experts on the MERG site I've been pointed at similar examples of yard exits from the GE at places like Wimblington and Halesworth on signalbox.org. It appears that I should probably not have the lever 15 on the frame and instead have it as a yard point but this leaves me with the aesthetic problem of having a lever frame and then a separate 'odd' lever on the layout. Any ideas?

 

I like layouts at this stage, there is no track work for the trains to fall of.

Hi

 

Do you realise that 10, 14 and 18 would probably been yellow disks. This would allow a train to shunt past them in the ON position, provided the points were set away from the main running lines..

Hi Liz

Yep, a mix of nice old GER rotating head signals and more modern ones!

Do you not need a further shunt signal to control the release from the second siding on the bottom pair?  As you have a double slip, either siding can exit directly onto the main line.

 

This would mean that 15 would need to be controlled from the box, as it would need to be locked.  No 16 is the one I think ought to be on a ground frame!  So one problem solved and another created - sorry!  However, do not get upset by popping one lever into the frame, I dare say it happened in some places.

By the 1950's-60's there had been quite a lot of rationalization particularly with relation to shunt signals. My friends on the MERG reminded me about the excellent resources on signalbox.org and I found plenty of examples (e.g. http://signalbox.org/diagrams/wimblingtonc1960.jpg) where the exit only has a single disk.
