Physical Components



The Layout Board

A 2500 mm square board hoisted from an I beam on the ceiling (designed to always keep the board level)

The Platform hangs on 4 wires - located at each corner


The whole layout was then built up on this board with three main levels :-

Lowest in the middle,

A half height section with the main 4 platform station at the front

And a higher section at the back with a small 2 platform station, hills and tunnel section



OO Guage Track Information



A Hornby Elite Controller mounted on the front of the layout

enabling both manual and computer controlled running of the trains, points etc…


The Railmaster Computer which simply runs Hornby’s Railmaster software.


This software gives us control of train speeds, direction, point control etc… but it is purely a “Time Based” system which enables sequential scripts and loops with NO REAL LOGIC !

The computer is attached to the Hornby Elite controller via USB


Hornby did make a modification to Railmaster in 2019 which allows us to send “External” commands to interface with other software but there is no API and thus no way of pushing input back into Railmaster


Power Supplies


There are a number of power requirements :-


The 15 Volt AC output from the Elite is distributed via a star like wiring frame across the layout

The Elite itself is powered by a mains supply/adapter from the right hand side of the layout

A 12 Volt DC supply is similarly provided across the layout – This 12 Volt Supply is provided by a transformer dedicated to this purpose. This supply is at the back right hand corner of the layout

A Supply to the Powered USB Hub  from the adapter supplied with the hub – this is necessary for the sensors and relay board control. The adapter power supply is from the right hand side of the layout alongside the Elite power supply

There is also power to speaker systems etc… including 4 quad speakers (mounted at each corner of the board)



Three Types of USB Electronics Boards mounted centrally on the layout (under the village scene)


Denkovi Relay Boards

we have three of these boards – they attach to our main computer via USB and each of them has 16 relays that we can switch – they are currently used for track isolation at platforms and for light control


The Relay Boards are mounted on to lower panel underneath the village scene as shown here (the digibee sensor board can also be seen to the left)





DigiBee+ Sensor Board

This board has 16 inputs that are fed from reed switches around the track – this enables the software to see where trains are, what direction they are travelling and then calculate the speed of trains

The centre picture above shows the press buttons I included for the DigiBee board - these allow simulation of sensors being activated (for circuit and sensor testing purposes)

The photo on the right shows the resulting wiring mess !

See User Guide :- digibee+ manual

Note - the board also allows some outputs but, at this time we are only using it for sensing puposes



Mini Maestro Servo Board

This board allows us to operate servos (as in radio control models) and therefore create movement on the board - we have not, as yet, made much use of it !
