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 and SPROG3 provide a one-stop source for setting up and running any DCC locomotives.

  • SPROG 3 has 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 $100!

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, or just to take the task on for you, we offer decoder installation as a service.

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.
It comes unlettered, and the "GW" and "12" on this example are just to illustrate potential cusomization that you might make.

The basic power chassis used in the switcher is also available - 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.
