No. 73 108 in late condition, photographed at Eastleigh in 2002.
Faded, dirty but still doing its stuff on the SE TPO.
No. 73 108 is one of the locomotives I have chosen to model using one of the two new Dapol models to recently arrive on Folkestone East. Conversion to EM turned out to be the simple, involving the regauging of the split axle wheel sets which have a good profile on them – good enough to run smoothly through my hand built track.
There are many well-thought out technical features of this model. The body lifts straight off after releasing the retaining screws – no pesky clips to fight. Don’t loose the screws though or you will be scr*wed when it comes to putting the body back. There is a good space for both decoder (nearest) and a sound speaker. A 21-pin socket ensures all lighting features have power.
The circuit board makes contact with circuits in the body by means of a row of sprung contact pins which eliminates linking wires and plug and sockets. However, I did not want the cab lights illuminated and was looking to fit a decoder with ‘stay-alive’ (‘keep-alive’) . The only one I had to hand was a wired LaisDCC one which works well with this mechanism. 21-pin versions with stay-alive are also available. I also wished to work the head code lights independently using red LEDs, so decided to remove the circuit board and hard wire a LaisDCC decoder in place with its stay-alive capacitor. The lighting connections to the circuit board are easy to locate and desolder, so this hard wire DCC conversion is easily reversed – the circuit board being stored away safely.
The image above shows the hard wire installation, with the head light LEDs wired with 5k Ohm resistors to reduce the fierce light to something a little more realistic. Connections will be made with the head code box LEDs too.
A stay-alive unit is seen in this image. It was not quite powerful enough to power the Dapol Class 73 when it lost contact through those pick-up bearing rings. In the end, I built a new stay-alive unit with some higher Farad rated capacitors with great success. The higher rated unit was still connected to the same LaisDCC decoder. It is worth mentioning that even the smallest capacity stay alive unit will prevent light flicker in the most reliable models even if there’s not enough juice to deal with a serious stall. In many instances, the flywheels fitted to modern mechanisms will carry a loco over a minute dirty spot without interruption,. The only hint of a problem will be a flickering of LED head and tail lights. Stay alive units also smooth the operation of locomotives that otherwise seem to run well.
A final look at the DCC installation. It may seem strange to remove the convenient 21-pin DCC interface. However, wired decoders offer so much more flexibility in terms of organising lighting effects and this installation turned out to be quick and effective. The model is numbered 73 108 with an address of 3108 and is now hauling trains on Folkestone East. It is at this point I must admit to keeping two Lima EDs, stripped of drives and in the process of being reworked with Dapol detailing parts. One is No. 73 129 ‘City of Winchester’ which is used as a trailing unit in the SE TPO so the train can be top and tailed. Two Dapol EDs on this train is overkill. The second loco was also a regular on the SE TPO: No. 73 131 which will eventually be refinished in EWS livery.

Despite the long silence from me on the N gauge front, work has continued on Dudley Heath, my little portable N gauge layout which has appeared at Doncaster and Ally Pally this year (project in progress). Just commissioned and placed in service is a 5-car NR New Measurement Train model based on the Dapol HST NMT train pack and five rebuilt Dapol Mk.3 trailers. The original plan was to use Electra Railway Graphics overlays on Graham Farish Mk.3 stock. Before work commenced, a set of etched conversion parts for six NMT trailers arrived, out of the blue; kindly sent to me by Pete Harvey.
No disrespect to Adam Warr – his vinyl sides are really good and I have a number of converted coaches (and one wagon) running on Dudley Heath. There are more to add to the roster – the Class 310 or 312 in West Midlands livery is very tempting indeed! (RFM below is one of the Mk.3s I have converted using Adam’s sides.) He also kindly produced Folkestone East name boards in NSE style for me; both sun faded and full colour.
However, I had three Dapol Mk.3 trailers surplus to requirements – blue grey ones with no immediate use leaving only two to buy. Also, I fancied having a go at a different type of conversion in N gauge. The results are pretty reasonable, except colour matching to Dapol’s version of NR yellow was not easy nor was it a precise match in the end. A 5-car set is also a big project to complete, hence the relatively long periods between posts on here – there’s not been a lot to report of late.
Detailing of Dudley Heath continues on several fronts including signals and line side equipment. The Graham Farish Class 350 will find a home on the layout too, after I have closed up the coupling gaps between the trailers! A fine model in its own right, it adds further modern West Coast flavour to the layout. The foot bridge was a complex beastie to scratch build but despite that, I am not totally satisfied with the result (some filling, repainting, detailing and weathering will improve its appearance dramatically). I will probably have another go at building it once the layout reaches a sort of ‘finished’ stage. I will finish the layout to a good enough standard and then go back and rework bits of it, in between work on Folkestone East and the Montana Rail Link layout. In the meantime, Dudley Heath lives safely in its box under the MRL layout, safe from dirt and dust until I get the urge to play with N gauge British outline models once again. Then out it comes!

Wow! That’s some printing job in N gauge. It’s a Dapol Class 66 finished as GBRf 66 720 with it’s special ‘Day and Night’ graphics applied to the sides – the result of a competition for children of GB Railfreight staff.The dark side of the model. In other words, the ‘Night’ graphic showing moon and stars – pretty bright in reality.On the lighter side: the ‘Day’ graphic with hills, rainbow colours and birds.
Apart from the locomotive body sides, the rest of the locomotive is finished in GB Railfreight colours with orange cabs, blue roof and the new company logos. On a model, it is strangely attractive!
I guess the idea of the design is to show that GB Railfreight operates both day and night. Some die-hard enthusiasts may find such colourful graphics a little startling and not to their taste; however it is a one-off and who knows how long the locomotive will wear these graphics? In the meantime, Dapol has really done a great job of them, recreating the vibrant colours on both sides of its low emission Class 66 version of its model with sharp printing over the fluted sides of the locomotive. The model itself has the usual features including 6-pin DCC connection, full lighting and a slow control motor. Will it make it onto Dudley Heath, I wonder?
Progress on Dudley Heath
The N gauge layout will be heading to The Festival of British Railway Modelling exhibition in February, warts and all. The event is held at the Doncaster Racecourse and is only a few weeks’ away. I had to pull my finger out and make some progress on some important features including the station platforms at Dudley Heath which are now complete following some messy work with Hydrocal and pigments.
It’s great fun doing this sort of structure modelling. The appearance of the layout is transformed pretty quickly by the addition of structures and civil engineering features. Ballasting is complete now the platforms are in place and other engineering features built in, including cable ducting troughs and equipment box bases.
