Who are GFB Designs?

TrainTronics TT300 DCC Point Motor - developed by GFB DesignsGFB Designs, are an electronics consultancy business, operated since 2005 by Fraser Black, specialising in the model railway market.

Fraser has over 30 years of experience in the professional electronics and software design industries.

Following a number of years designing products for other manufacturers, we now design and manufacture our own model railway products for operation on either Digital Command Control (DCC) or conventional DC ("Analogue") power, placing emphasis upon ease of use for all modellers.

 

Who are CML Electronics?


In 2016, following the offering of the business for sale by the previous owner, we took over the operation of the successful CML Electronics business and continue to promote and develop the former CML product range alongside our own, but please rest assured that the products will still be of the same high standard and quality you have come to expect from CML in the past.

At the moment, we have no plans to change any specifications or product names (or numbers) for the excellent CML product range and we are delighted to be able to add these items to our existing range of DCC accessories and Controllers. 

PLEASE NOTE: During this change-over period, there may be some residual references in articles and product manuals to "CML Electronics Limited" or their contact details, this is to be read as now being "CML Electronics, operated by GFB Designs", with the contact details being as on our Contact Us page.
