Many thanks. Now I can fill the gaps in my collection.

The single ground signal that I have working I made from a kit some time ago and can't remember the make. It has a white metal body and etched disc.


Sounds like a MSE one (model signal engineering)

That makes sense. Thanks Jim. I’ll place an order right now.

Re: Lever Frames

then add 20 working ground signals ( 3D printed ) Doug, I've just come across this thread whilst looking for anyone's shared experience on making working ground signals. You mention 3D printed. Did they work out for you? I'm a real novice and have no experience with such things but, having now got ...

Re: Lever frame mk 2 and the locking frame

I am sure you will spot further issues - please feel free to let me know. It has been mentioned that there are plenty of spare nibs and bridles etc. within the etch. So, (here I place my tongue firmly in my cheek and I use the word 'cheek' advisedly), there is one thing that I can think of that is ...

Re: Block Bell wiring

All that demonstrates that the internal wiring is not as supposed so the only way to resolve it is to trace out the wiring. Sorry Keith, You were spot on. The rear connection is superfluous in a simply wired bell system. C is negative feed and, once again, I needed to bring C from the other bell to...

Re: Block Bell wiring

The standalone bell in the bottom two photos only seems to have E, C and L, no Z. That suggests E for the + battery/bell connection and probably c is the common return, you should be able to trace those wires easily enough. . Keith, You would think so! However, although I've traced the Z to the rea...

Just to mention that your wires might be a bit on the thin side Howard, I would have thought you and Keith have learnt your lesson after the locking frame project. :D I'm nothing if not ambitious! You won't believe this, and in view of you mentioning wire size I should probably keep it to myself, b...

Re: Block Bell wiring

Thanks to the responses I am now feeling that I ought to have checked the diodes orientation prior to starting this thread rather than assuming that I had everything right and imagining that there was some other problem. Having revisited my bells and chec...

Which way round have you fitted the diodes? Alan, my ignorance is exposed already. I have six bells and, if I remember correctly, on the basis that I don't know which direction the power comes in from, I merely tried them using crocodile clips until I found a way that stopped the interference with ...

Block Bell wiring

I'm using block bells in order to pass trains through my Absolute Block sections, along with the fully interlocked lever frame. A slight problem. When using the bells there was interference with the LEDs in my Megapoints Controllers panel for my fiddle yard. It appears that there are spikes created ...

Re: Lever frame mk 2 and the locking frame

Yard to Up line is not a "wrong direction" or "backing" movement You are quite right Noel. That was very clumsily put. What I was trying to indicate was that the signal face would not be seen by a driver on the main line and, therefore, no need to consider the driver seeing a re...

Re: Lever frame mk 2 and the locking frame

I will use Red/Green aspects on all Ground Shunt Signals with the exception of the Loop access which will be White/Green as described earlier.

Re: Lever frame mk 2 and the locking frame

Another thought following my experience with making the locking frame.

Re: Lever frame mk 2 and the locking frame

Early 1950s but, as Noel implies, they were only used for new works or necessary replacements so they were never very common.


Agreed, I can't see my little station yard being upgraded, even though it was on a main route.

BR(WR) used a yellow arm on white disc, and yellow and green aspects, for conditional ground signals, but I don't know when the change took place; it was not retrospective, so such signals were not very common.

Very unlikely as that would imply they are locked by the Block/Token instrument.

Alan,
Many thanks for that. I wasn't certain, though I feel I should be, as to whether the levers for disc signals should be painted differently to main line stop signals.
