Due to the continued shortage internationally of some components (including screens and some microcontroller chips used on our control boards), there are still delays in obtaining some components; with some lead times currently being quoted as up to 12 months, and some having been extended or pushed back already by manufacturers.  This is severely impacting our ability to manufacturer a number of our products at this time.

We are not the only manufacturer that has been impacted by this, and we hope that you will please bear with us whilst we work to get back up to pre-Covid stock levels and availability.

Currently, we are still awaiting two components for the ACE that will not be available until around October, so our next batch of ACE controllers will not be available until early winter.

We will continue to update this article as changes occur.

From Monday 4th January 2021, the postal address of Sig-naTrak by GFB Designs will be:

GFB Designs, 13 Hooper Close, Dunswell, Hull, HU6 9FG.

Whilst we have updated the address on our website, some of our products and instruction manuals may still have our previous address in Stockport. This is to be disregarded, and our new address in Hull should be used for all correspondence. Our documentation will be updated as soon as possible on these items.

We are pleased to report that, amidst the gloom and challenges associated with the Coronavirus pandemic, we are now able to re-commence some development work and improve on our manufacturing levels! This is the current status:-

  • A new batch of ACE-2 DCC Controllers & DRIVER Handsets is in production and should be available within the next 4-6 weeks.
  • The GEM and RAS1202 will be unavailable until further notice. IMPs are manufactured to order, with a lead time of around 2 weeks.
  • Please allow up to 21 days for delivery of orders. Realistically, however, we can generally ship in-stock products within one week.
  • The ACE software upgrade, to V4.0 with PC control, should be available by early Autumn (2020).

Design and development of the following products is still “on hold”:-

  • LYNX LocoNet® and XpressNet interface for ACE
  • TROJAN Power Booster Module for ACE.
  • SIN16 LocoNet® Sensor Input Board
  • Any other products not yet released but discussed for future release.

We will update this article as changes occur.

Due to a slight delay in the manufacturing process, we are sorry to announce that the ACE-2 units that we had hoped to be in stock by the end of the month should now be ready to ship in around 3 weeks and should be ready for release at the Lancashire & Yorkshire MRC "MRX" show at the Manchester Museum of Transport on the weekend of the 20th May 2017! 

We apologise for this slight delay but assure all customers who have pre-ordered that they will be shipped as soon as they are in stock with us and have been through our testing process.


GFB Designs and Digitrains are today pleased to announce that Digitrains now stock the Sig-naTrak® ACE DCC System.

Digitrains are in attendance at all of the larger and many smaller exhibitions throughout the season and have a wide range of controllers from not only Sig-naTrak® but other manufacturers on their stand for you to test and get a feel for at exhibitions and in their showroom in Lincon City Centre.

We have today released the USB Interface Module for the ACE DCC Controller for pre-order from our shop.

It will be available for collection from the Warley Exhibition at the NEC at the end of November, or for those not attending the exhibition, will be posted out on 1st December.

The UBI2044 is used for updating the firmware on the ACE DCC Controller, and it is intended, also to be used for PC Control in the future.

The latest version of the ACE Firmware (v3.20) will also be released at the same time, and this includes the following updates to the ACE software.

  • 16 user assignable function sets, allowing locomotives to have individually named function buttons. This is especially useful for DCC Sound fitted locos.
  • Faster response times to the touch panel and from DRIVER handsets to allow for easier DCC sound control.
  • Factory Reset and Touch Screen Re-calibration functions.
  • Emergency Stop software updates.
  • Internal code structure changes in preparation for LocoNet® and PC control functions.

The UBI2044 USB Interface Module is available to pre-order now from the Sig-naTrak website for only £30.00

Well, tonight we have been burning the midnight oil putting the finishing touches to our new printed brochure/catalogue which will be available at the Warley National Exhibition at the NEC in November.

Here's a sneak peek ...

We are pleased to announce that we reduced the price of our RCS0009 from £3.90 to £3.00(ea).

Unfortunately however, due to increases in the cost of components from abroad and the continued fall in value of the pound, we have had to change the prices of our GEM Digital Point Decoder, IMP Digital Servo Controller and Relay Accessory Switch.

To try to combat these price increases, we have also introduced our 6 & 10 Pack price discounts to the Relay Accessory Switch (RAS1202) & Remote Control Micro-Servo (RCS0009), and increased the discounts available with the GEM Digital Point Decoder (DPD2001) and IMP Digital Servo Controller (DSI1001).
