Going back to the track layout as modelled, and assuming that the loop is used as a running loop or refuge, what is more likely for trains passing from the loop to the next section: a dummy at the loop exit and an advanced starter; or a running signal, level with signal 8, to enter the section and shunt-ahead signals for local moves?

The type of exit signal used would depend on time and place, as different companies had different approaches. A ringed or reduced arm on a post would also have been common. However, an advanced starter [assuming the existence of signal 8] would be virtually inevitable, since all trains using the loop would have to reverse in. Use of a 'Shunt ahead' signal permitting access to the forward section to enable the train to reverse back would be very unusual, if not entirely unknown, in this context, on a double track line at a country station, I believe. In signalling terms, though, there is no requirement for signal 8; a single starter over a train length beyond the entry to the loop would be all that was required, in the same way as for travel in the opposite direction.

In the layout as modelled there is facing entry to the loop so no need for trains to reverse in, I would still have the section signal (starter) beyond the exit points but less than a train length, just some shunting space. Then a disc exit is fine, loop entry could be an offset bracket with small arm or a co-located disc with the home.

I admit I was looking at Alan Turner's diagram when writing my last post. Ooops!

Right way round now and surprisingly they work. That's a small step for a finescale modeller but it's a ruddy great leap for me! I've tried in vain to add coloured lenses to the spectacles. Any suggestions?

Somehow the picture goes upside down when I post on the forum.
(hopefully corrected for you, did you take the pic on an iphone or ipad? Keith)

PVA and coloured inks?

Humbrol Clearfix plus translucent paint [try your preferred search engine - Vallejo is one that does these, there are probably others].

Model Signal Engineering supply packs containing four sheets of spectacle glazing material, one each in red, amber, blue and green. Each sheet measures about 2" X 2", so ample material for lots of signals. MSE components are available from Wizard Models and a pack of the material will currently set you back £2.50. Fiddly to cut to correct shape for the spectacles, but warranted by the excellent work already done on these signals. I assume that blue will be the correct colour for the 'clear' aspect spectacles.

Edited to add that the latest photograph and your post sugges that you may have already tried this material without much success. Would it help to file up two bits of brass so that they are a close fit within the etched spectacles, then use these as patterns for cutting the material (one pattern for upper spectacle, the other for the lower)?

Thanks everyone. I'll try the following and some Vallejo and see how that goes:

Personally, I much prefer the original Microscale Kystal Klear to Humbrol's somewhat shoddy ripoff, but each to their own. What you will find is that all such window glues, to a greater or lesser extent, produce a dished 'lens' rather than a flat pane. Sometimes this can be used to advantage, sometimes not. I have a Sentinel Steam Lorry that has been in the repair shop for much longer than I care to reveal, because I took the shortcut of Klear for the top half of the windscreen (it has very shallow upper 'windows' above the main screens, each split by a central divider). It seemed to work at the time, but the more I looked at it the more dissatisfied I became with the contrast between flat larger panes and dished smaller ones. Sometimes there is no alternative to a fresh scalpel blade, a well-held piece of clear plasticard, and a pint or two of concentration to produce satisfactory glazing.

I use the coloured cellophane sold by MSE for this. I secure it with varnish. A lot easier than the other suggestions in my view.

And remember that the green lens is in fact a blue colour (because the white light of an oil lamp is in fact yellow).

An example can be found here: https://highlandmiscellany.com/2014/04/ ... d-etching/

Love the somersault signals by the way - well done!
