DIGITAL: A train command system, fast
gaining ground on older Analogue systems in terms of
popularity. Whereas analogue systems work by providing a regulated
supply of power to the track that increases or decreases according to user
input, Digital systems supply a constant power supply to the entire
layout. Trains are operated through a command signal, sent through
the track to the locomotive. With each locomotive operating on it's own frequency, locomotives can be commanded
individually. See the article Introducing
the World of Digital for a more detailed description.
ACCESSORY DECODER OR MODULE Used to control any
accessories on a layout, such as signals, lighting, points and so on.
ADDRESS: A number identifying each
individual locomotive and accessory decoder on a layout. When a
controller is set to a particular address,
BOOSTER: Used to supply power to the track,
and to increase the rating on an existing supply. One or more can be
used alongside the Command Station.
COMMAND STATION: The central hub, or brain of
the Digital system, this unit is where control data is converted into
electronic format before being sent to the track.
CONSISTING: See Double Heading
CV: Configuration
Variable. Components within a decoder which store
the characteristics of that device. Each component has it's own reference number, and these can be individually
programmed.
DCC: Digital Command
Control. A control system for Digital model
railways that is now the most widespread system worldwide. The
standard set down by the NMRA (National Model Railroad Association) in the
DECODER: Circuit board used for operating
Digital models. Any locomotive or accessory to be used on a digital
system requires a decoder, which receives and interprets the Digital
information sent by the Controller. Many decoders offer added
functions such as lighting, sound and so on. These are referred to
as multi-function decoders.
DOUBLE HEADING: Often known as consisting or
multi-traction, a means whereby two or more locomotives can be run together
under the same address.
MULTI-TRACTION
NMRA CONFORMANCE: Products that have passed
the NMRA's testing procedures are eligible for a
Conformance Warrant if the manufacturer also agrees to fix any discrepancies
that might become apparent in the future. The Conformance Seal is
awarded by the NMRA for products passing the Conformance and Inspection program
for particular NMRA standards.
NMRA STANDARD: A code of practive developed by the National Model Railroad
Association in order to acheive standardised
decoder formats.
PROGRAMMING: The action of setting the internal
parameters of decoders and other control equipment. During
programming, values are set for CV's to determine the characteristics of
locomotives, decoders and other programmable Digital devices.
PROGRAMMING TRACK: Many
Digital systems require a Programming Track separate from the rest of the
layout on which to perform programming operations on locomotives.
ROUTE: The simultaneous operation of a
series of points along a designated section of your railway.
SPEED STEPS: Controllable voltage increments
which are used to control motor speed on a locomotive. Some decoders
allow the output power to be set for each speed step. The range from
zero to full power is divided equally into 14, 28 or 128 speed steps.
WHAT IS DIGITAL?
The main difference between a Digital system and the more traditional Analogue system is the way that the power is supplied to the layout. The philosophy is that the user controls the train rather than the track that it is running on.
With analogue control, the user sets the desired speed of the locomotive, and this determines the proportionate amount of current to be supplied to the track by the controller. The disadvantage of this method of control is that each train on the track will respond in exactly the same way. In order to have different trains running in different directions and at different speeds, a layout has to be broken down into different sections of track each with an individual controller.
With Digital control power is supplied to the track
constantly, and each locomotive will respond
This means that each train can be controlled individually without the need for different track sections and all the complications involved in breaking one layout into separate, isolated electric circuits.
WHAT ARE THE BENEFITS OF DIGITAL?
The first benefit of a Digital system over Analogue comes in
the building of a layout. Without the need for isolated sections,
the wiring required is significantly reduced in an instant. On a
basic layout with digital control power can be supplied to the track via
From an operational point of view, digital brings a number of benefits:
·
Operate more trains simultaneously on your layout.
One controller can be used to set the speed and direction of a train, then be switched to take control of the next train without disturbing the control of the first train.
·
Each locomotive responds to individual commands.
Every digital locomotive contains a decoder with an
"address". Commands for each locomotive will be "delivered"
·
Double heading and multiple units.
Multiple train control opens up the possibility for
replicating Double Heading, Banking Locomotives and other prototypical railway
operations that are
·
Lighting, Sound & Steam Effects.
With digital comes the ability to control additional functions within each locomotives, such as directional running lights, interior lighting effects, on board sound effects and smoke generators for steam locomotives. Whilst these functions can be found on analogue locomotives, digital brings a new level of control, with the user able to activate/deactivate individual functions as and when they want, as opposed the "always on" nature of analogue.
·
Additional locomotive functions.
Other functions such as controllable couplings and pantographs, shunting speeds and so on can be found on digital systems, all of which add to the involvement level and fun-factor for the modeller.
·
Control of trackwork
& accessories.
Most digital systems will offer the user the opportunity to use decoder-fitted accessories such as signals and point motors. This will bring the same level of control to these accessories as with the locomotives, such as the ability to change sequences of accessories with a single push of a button.
These are just some of the features of digital control currently available. There are many more, and the scope exists for future expansion. All of this makes digital control the most exciting technology in the modelling hobby, and it is fair to say that the possibilities are almost endless when it comes to operating a layout and replicating what you might find on the real thing.
WHY START WITH DIGITAL RATHER THAN
ANALOGUE?
In addition to all of the benefits listed above, it is also important to consider future developments. Whereas the advancement and improvement seen in analogue control is now limited, digital control has the potential to continue growing and improving for many years to come.
For those making a start in the hobby, digital offers a much easier introduction than analogue, as the work involved in setting up a reasonable layout is much less, and much simpler, and the potential much greater.
Far from being "too complicated" or "just for experts", digital is in essence ideal for beginners, as it lends itself very well to a smaller layout, but can be easily expanded and upgraded as well. www.Cravenmodels.com

many different power supplies available within the Model Industry.
Please read
all the manufacturers instructions before attempting to connect any power
supply to an electrical device.
Using an incorrect
power supply may damage the product It may work initially but may burn out
due to incorrect voltage or amperage being used. There are supplies that are DC or AC. The correct one must be used.
