DCC Control and Programming
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.
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.
provides the same programming and control features of the SPROG II, in the same compact package,
but with a major increase in available power output.
The power increase is really useful for those wanting to run their layout from DCC, in the most economical way.

In addition to the layout operation possible with the SPROG II or SPROG 3, 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.
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.

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.

Our additional products and solutions
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.

We also offer the Bachrus DCC speedometer, available in N or HO scales,
which is ideal for setting up and speed matching locos on the programming track, in conjunction with your SPROG (or other DCC system), computer and DecoderPro.
Supplied with sufficient rollers and rails to support 8 powered axles (think articulated steam, or big diesels) and a tender or other unpowered wheels, these are ideal complements to your loco setup environment.

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.

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.
