DCC Control and Programming

SPROG image

Controlling model railroad operation increasingly uses DCC, and the SPROG DCC device is the ideal solution for programming and maintaining your fleet of DCC-equipped locomotives, in any scale from Z to G!
With the industry's most comprehensive support for decoders from all the leading manufacturers, SPROG II, SPROG3 and Pi-SPROG family provide a one-stop source for setting up and running any DCC locomotives.

  • SPROG 3 and Pi-SPROG have sufficient power to program sound decoders, even in large scales, so no power booster is necessary.
  • The SPROG works with all those "difficult" decoders that don't seem to read back on other systems.
  • SPROG II & 3 also includes the ability to run your layout, with on-screen computer control, and full DCC operation.

See the SPROG DCC full details, and to order your DCC programming solution. DCC Programming and Control starting under $120!

Layout Command Control (LCC)

We are pleased to now offer our family of LCC solutions for layout control to the NMRA LCC / OpenLCB standards and specifications.
We offer interface, power and connectivity solutions, together with general purpose IO and Servo IO modules, with more solutions planned.

See our LCC page for full details of the range of products.

DCC Decoder Installation

Installation of the decoders into many locomotives is now a straightforward process, with more "drop in" decoder models available from several vendors.
For those more unusual installations, we had extensive experience in decoder installation as a service, but no longer can offer that.
Follow the link to find out more, or just to see some step-by-step examples as well.

Speedometer Solutions

Running your trains can significantly benefit from understanding how fast they are going,
and also from matching the speeds of your many different locos in order to be able to run them together. Accutrack Speedometer

In past years we were able to offer options for tracking the speed of your locos, running on the layout or during setup, but those systems are now discontinued and no longer available. We can still provide some support and assistance when you need to get the very best out of your fleet.

Track Power Indicator

Track Power Indicator

Our custom track Power Indicator is designed to clip onto the rails of any scale from O to Z, and provide an instant indication of the presence of power.
Showing a Red aspect for positive power on the flexible lead, green for negative, and orange for DCC, this can help show that the power is present, and aid in diagnosing strange track power behavior, troublesome locos, etc.

N Scale Locomotives

Now available from us online, a small switcher loco, and a small chassis for kit building.

loco imageThis little switcher has a Japanese heritage, but would not be out of place - with appropriate paint and logos - in many industrial yards anywhere in the world.
The switcher comes painted as shown, and with a number of separate detail parts, such as the smokestack, horn and railings seen here, for the modeler to apply as you choose.
Including a powerful motor with gear drive to the axle, and directional LED lights, this is a useful and surprisingly powerful little unit.
It comes unlettered, and the "GW" and "12" on this example are just to illustrate potential customization that you might make.

The basic power chassis used in the switcher is also available separately - with different LED lights fitted - here, in very limited quantities. SPROG image

Each unit includes 12v motor, directional forward and reverse LED lights, all wheel pickup and impressively powerful traction for such a small and light unit.

To buy either of these little units, please see our Online Store.

What is N Scale

Model railroads come in many sizes, and at the BBM Group we specialize in N Scale, with a track gauge of Nine millimetres.

The second most popular size in model rail today, "N" trains run on track with a gauge of 9mm, available from many vendors in ready-to-run and customizable form.
However, strangely enough, around the world there are three different sizes or scales in use for "N" gauge! In the USA and related markets, and in most of Europe, the scale is 1 to 160, while in Japan they adopted 1 to 152, and in the UK it is 1 to 148.
