GFB 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.
Sig-naTrak is the registered trademark and brand name that GFB Designs promote our range of model railway electronics with. This includes the DSI1001 IMP Digital Servo Controller, the DPD2001 GEM Digital Point Actuator and our recently launched ACE DCC Controller & Command Station featuring a full-colour touch screen.
