DCC Control and Programming

SPROG II

Controlling model railroad operation increasingly uses DCC, and the SPROG family of DCC devices
offers 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,
the SPROG DCC family offers the easiest DCC programming, and the power needs to run your layouts.

Easy programming!

SPROG II and SPROG 3 both offer full NMRA standard DCC programming for any manufacturer's standard-compliant DCC decoders.
Both are supplied with full software, comprehensive installation instructions and a lifetime warranty and support.
The difference is the power available. SPROG II is ideal for smaller scales, and comes with a 12V 1A capability; SPROG 3 provides exactly the same programming and operation functions, and also offers 14V or 18.5V, 2.5A capacity for larger scales, or for some of the newer sound decoders that like a little higher voltage for reliable programming.

Layout Operation

In addition to the layout operation possible with the SPROG II, SPROG 3 or Pi-SPROG, SBOOST allows you to split your layout into self-contained power districts, include auto-reverse sections and expand your layout possibilities. And for the most economical layout operation configuration, the SPROG Nano drives any number of boosters from a simple computer connection.

SBOOST is specifically designed for use with SPROG II, SPROG3 or SPROG Nano, and the new Pi-SPROG, and allows for more power districts, and also auto-reverse sections.

SNano SPROG Nano is a low cost USB interface that allows your DCC power boosters to be connected to a computer running Windows, MacOS or Linux.
The ideal companion to the SBOOST, SPROG Nano interfaces your computer in the most compact package.

Model Railroad Speedometers

Accutrack Speedometer

Have you ever wanted to know the scale speed that your trains are achieving? Now you can do so, easily, with our layout Model Railroad Speedometer.
Programmable from the front panel for N or HO, miles or kilometers this unit stands over any track,
and displays the correct scale speed of a train as it passes, in either direction.
Suitable for DC or DCC, the unit runs from two AAA batteries (included) and has auto power off when not in use.

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.


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.
Straightforward control, lighting and effects, or DCC sound, in any scale; we will be happy to propose an installation to suit your needs.

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.
