Welcome to GFB Designs!

We manufacture model railway layout control products for operation on either Digital Command Control (DCC) or conventional DC ("Analogue") power. We also supply electrical components (e.g. wire, switches, connectors etc) to support these products.

New information is added to this site as/when available so please keep returning!

All our items may be purchased from this site, or by calling us on 0161 883 2022.

UNFORTUNATELY - At present we can only supply to UK/Europe owing to variations in trading standards regulations. In time, we will be certifying our products for the global market (e.g. USA and Australia).

PLEASE NOTE - You do not necessarily have to register on our site to make a purchase.

Price changes....

Unfortunately - due to production costs and component availability issues - we have had to increase the cost of our GEM, IMP and Relay Accessory Switch. However, we have been able to dramatically improve the savings available when buying our GEM and IMP bulk packs. Also, the price of the RCS0009 servo has been reduced.

Thank you for your understanding.


An update......

Our new website is now up and running at www.signatrak.co.uk.

This new site has our complete product range, online shop, news and information and should provide a more "user-friendly" and dynamic presentation for you. Both the CML Electronics site, and this current (gfbdesigns) site will soon be closed down.

Many thanks to our publications and publicity officer for his hard work in setting up, and maintaining, our new (signatrak) site.

If you have any general queries, or problems with ordering, please contact Fraser via info@signatrak.co.uk or  gfbdesigns05@btinternet.com, or on 0161 883 2022.

(GFB Designs aquired CML Electroincs in April, this year. CML was a very successful business producing DCC accessory modules specifically designed to connect to the LocoNet(R) network and we are delighted to be continuing production of these units.)

(LocoNet(R) was designed by Digitrax Inc. and portions of LocoNet are covered by US Patent Number 6,275,739. GFB Designs hold a development/manufacturing licence in order to utilise the associated intellectual property.)
