Mitigation of radio frequency interference of DCC commands induced on trackwork

Revised wiring of Die Keinnamebahn to prevent mobile phone interference

I have now completely rewired the underside of the nine baseboards that comprise Die Keinnamebahn. The following tasks have been completed since our recent RF induced system failure at the Bakewell show. All power/DCC buses under the boards have been replaced with 2mm diameter solid copper wire. As many track feeds as possible have been […]

Radio Frequency Interference and a DCC disaster at an exhibition

DCC control signal pattern

We took our layout “Die Keinnamebahn” to the Chesterfield Model Railway Society annual show at Bakewell, Derbyshire for their weekend-long exhibition. We set up on the Friday evening and immediately had DCC control problems. Locos would start in the fiddle yard but would be jerky in operation and would ‘die’ about 1/4 of the way […]

ESU Loksound DCC sound decoder programming/mapping service in UK

ESU Loksound DCC sound decoders

I can offer a ESU Loksound sound programming/mapping service to customers in the U.K.  at an economical rate. I am able to program ESU decoders from V2 to V5 (but not the Loksound Select Direct decoders as these are not reprogrammable with a new soundscape). I can program any of the locomotive sound profiles available for download […]

New Roco 2095 OBB H0e scale locomotive with factory fitted sound

I recently bought a ‘surplus to requirements’ model of the Class 2095 narrow gauge diesel locomotive as used on the ÖBB line, amongst others, from a member of the Narrow Gauge Railway Modellers Online forum (www.ngrm-online.co.uk). This was an impulse buy, but the price asked and the wow-factor and reviews of this loco were irresistible. […]

Using DCC Concepts twin wire signals with the Train-Tech SC1 3-wire DCC signal decoders

Train-Tech SC1 DCC signal decoder

I wanted to use some DCC Concepts 2-aspect ground signals that I had bought. They came with two DCC Concepts Alpha Mimic LED controllers but at 50 UKP each, and capable of operating 24 LEDs each, they are too expensive to use on Die Keinnamebahn where only a few signals are on each board and […]

Hide your SSID when using WiFi control at exhibitions

JMRI running on a Raspberry Pi

I have been developing a JMRI (Java Model Railway Interface) DCC (Digital Command Control) system for my exhibition layout “Die Keinnamebahn” that uses mobile smart phones as WiFi connected hand throttles connected to the JMRI software running on a Raspberry Pi Model 3B+ microcomputer set up as a WiFi access point.   I got the […]

Using an uninterruptible power supply (UPS) on your model railway

Because we will be using a computerised, Raspberry Pi based, DCC control system with wireless hand controllers to control Die Keinnamebahn at exhibitions I wanted to protect the system from induced spikes or drop outs in the mains electricity supply. Dropouts can occur if someone accidentally, or inadvertently, unplugs a mains supply lead to the layout […]

Using bicolour LEDs to produce directional lighting on DCC locos

bicolour LEDS to replace 2 bulbs each end

Many commercially produced locos have bulbs or LEDs to illuminate the headlamps and tail lamps. Modern LED equipped locos usually now have bicolour LEDs to change between red and white depending upon the direction of the loco, but many don’t and just have a single colour LED or lamp that shows white only in the […]

Using Meccano to make a gearbox for motorising the Peco N gauge turntable NB-55

I built a turntable for Die Keinnamebahn and electrified it using Peco NB-55 n-gauge turntable kit and  a 10rpm geared motor, worm and gear obtained from China, via eBay. I had to build my own gearbox frame from strip brass, no easy task for this amateur metalworker! The installation worked but I wondered if there was […]

DCC power and control bus using pattern makers’ dowels with contact enhancement adapters

On my new layout I am again are using the brass pattern makers’ dowels that align the boards to transfer the DCC power and control signals between the boards. 2mm bare solid copper wire is  used to create a power/signal busbar between the dowels. The electrical contact between the male and female pattern maker’s dowels […]

Servo powered, DCC controlled, uncoupling ramps for 009 / H0e / H0m Bemo/REPA couplers

One of the problems with modelling in 009 / H0e / H0m / H0n30 is the lack of remote controlled decoupler systems at affordable prices. For those not wanting to exchange all their couplings for magnetic operated Greenwich etched brass couplings or Microtrains  or Kadee couplers the alternatives are either the manual Peco SL-430 uncoupler […]

Converting the Knightwing 0-4-0 kit to fit the Graham Farish Class 14 chassis

Now it was time to tackle the body modifications required to fit the 00-gauge Knightwing diesel locomotive body to the Graham Farish Class 14 n-gauge diesel chassis. The first job was to plate over the existing hole in the chassis plate using plasticard stuck to the bottom of the plate. This would give me flat […]
