Berko/Eckon are the most commonly available; Eckon are kits, Berco are ready-assembled. They are made by CCH Models who don't have a website, but Gaugemaster www.gaugemaster.com are their trade distributors. They are sold by various other model shops.

But you will find that they only have either a left or right 'feather'; using kits you might be able to make a signal with two feathers.

"Traintronics" are relative newcomers - they are at the Bournemouth Model Railway Centre - try www.slotrail.com I recall. But they are rather pricey in comparison to to the Berko/Ekcon range.

A look at www.ukmodelshops.co.uk using their search facilities may bring a few more up.

Yes, I confirm that Eckon do a British GPL (ground position light) signal. I understand it uses perspex or similar plastic light 'tubes' to keep the electronics below the baseboard to avoid trying to squash LEDs into the small-sized signal head. I think it is available either as the older red/white clearing to white/white or the newer type red/red clearing to white/white.

They've also just announced a three-aspect ground-mounted standard signal head. Not often used in real life but it has its place.

PS who or what are CR Signals?

 

[John Webb]

Thanks for the information on CR Signals.

QUOTE (Colombo @ 22 Feb 2009, 17:47) <{POST_SNAPBACK}>With regard to position light ground signals, there is a subtle difference between the older ones as depicted by the Eckon ES24 and more recent practise.

Originally stop was indicated by a red and a white light arranged horizontally and proceed at caution to the next stop signal was indicated by two white lights displayed at 45 degrees.

Nowadays the signal to stop is often given by two horizontal red lights, this being achieved by the light in the corner changing colour from white to red.......
As far as I am aware, the Eckon ES24 can show the more recent style by fixing red and white LEDs to the 'light pipe' going to the common 'lens'.

QUOTE ......The 3mm red/white LED can be obtained from a limited number of suppliers.....
So with the LED under the baseboard it does not necessarily have to be a 3mm one; this may give a wider range of choice.

The only GPLs and Anciliary lights I've seen modelled with LEDs actually in the head used surface-mounting (SMT)chips fixed in home-made Plasticard heads. These are described in "Model Railway Journal" No.171 published by Wild Swan Publications in 2006, on pages 311-317 in an article 'Scratchbuilding a modern bracket signal'. The signals described are used on the 'Widnes Vine Yard' layout of the Wirral Finescale Modellers, and are remarkable for their accuracy to the prototype.

And there is a full description of making multiple 'feathers' as well, also using SMT LEDs.
