    I have been playing around a little more with the sounds in 10001. I have settled for the moment on the class 37 sounds and horns, with the 37 engine sounds being a little more 'raw' than the more controlled class 31 sounds. The low tones of the 37 horns semm suitable, until I can locate something online that shows what the real single-tone horns actually sounded like.

    CV123 can be set with values from 0 to 5 to get the six separate sets of engine sounds.

    CV120 and 121 set the forward and reverse horn sounds.

    I had a little problem with 10001 surging at low speeds, so have tweaked CV211 for the BEMF settings - currently set to its highest value of 255 until I can work out a better combination of values in all of the related CVs that also influence and control the BEMF. I must check to see if I removed the capacitors too, as they can affect the operation of the BEMF on some decoders, whereas some other decoders seem unaffected by these.

    With the annual Model Bus Association of Australia's modelling competition looming in December, I decided I had better divert a little of my railway modelling energy to finishing some of the bus kits I started some years ago. I also finished off the London Country RLH uniform store started last week; you know how it is, with some modelling projects overtaking others. :D

    A quick scout of the Internet found a rear shot of 581 J (ex-RLH 44), revealing the rear number plate is wrong in the photo, and should have been a straight 1-line version rather than a 2-line one. I have replaced it now.

    The two Southdown buses have been sitting on the workbench for a lot longer, but I have now got around to tidying up the paintwork (still a little bit to do) before adding glazing as the next step.

    Work continues on the Little Bus Company Southdown Duple Coronation Ambassador kit. All that remains to be done now is to paint on the tail lights, print and fix some registration numbers (probably MCD 46), fix up the poorly fitted corner windscreens (the close-up photo cruelly shows them as looking really bad!), and give the model a good coat of varnish.

    Sorry about the stray cat hair on the rear end in the photo. :D

    You can really knock those kits up nicely Jeff. Great work and I like the liveries of your buses. The liveries had some class to them back then, unlike today ! :(

    Cheers, Gary.

    Yes, and Southdown was particularly renowned for its smartness - they actually looked after their buses and coaches then.

    I'm just working on another unfinished project, a Bristol RELL that I have been doing as a Thames Valley vehicle. Unfortunately for me, the TV REs had tall destination boxes at both ends, although when I started this model, I hadn't realised the back end had this feature as well. Anyway, thanks to some very helpful modellers in the Model Bus Federation Facebook group, I have a couple of photos and a set of blueprints to work from now, so work commenced wit some thick plastic sheet, laminated for the main body and heavily filed to blend into the roof curves. The next stage will be to use some filler, then a lot more filing, before painting it to match back in.

    The Southdown Leyland/Duple coach and the ex-RLH uniform store got first prizes in their categories last week.

    The finished RLH was shown before, but I never posted the photos of the finished Southdown coach or the Bristol RELL, so here they are. The Bristol was never quite right and needed a tad more work done on it, but I ran out of time.

    Continuing on with non-railway items, I have picked up on another bus kit started over a year ago but languishing on the workbench; another Little Bus Company resin kit, this time an AEC Regal IV with Harrington Wayfarer II bodywork, as used by Maidstone & District. It is getting close to the glazing stage, but I am still to-ing and fro-ing a bit with fine paintbrushes and the cream and green paints, as well as the silver and black fine lining on the raised trim. I have used BR multi-unit stock green for the green on this bus, and Humbrol #41, ivory for the cream. I think it should be slightly more yellow in tint, but they did tend to fade a bit.

    As with most of the other buses I build, painting the black inside the window rebates to disguise the depth a bit is a right royal pain to do, but well worth the effort for the improvement in the appearance of the finished result.

    For those of you who are Maidstone & District fans, here is the latest progress on the Little Bus Company AEC/Harrington Wayfarer II I have been working on. The paintwork is all but done, with just a couple of minor fixes needed. It is still awaiting number plates, destination screens, and the AEC badge (for which I have a few transfers).

    While my back has been limiting the amount of time I can spend leaning over the layout to do further work on that, I have been working through some of the bus kits I have languishing partly done on the workbench, or still in their boxes.

    Yet another 'delayed' bus kit is this original Aubrey white metal kit for a Bedford VAL with Duple Viceroy bodywork. It has been languishing in the 'to do' pile for a good few years. I had glued the body shell together, and started the painting, but that was as far as I had gone.

    I am doing it as a Shamrock & Rambler vehicle. It has now had another coat of paint, although there is much tidying up to do. One of the beauties of the white metal is it is much easier to 'polish' up the trim, which is also very convenient in tidying up the paint lines where they join.

    Not a new model as such, but new to me as I purchased it second-hand a couple of months ago. This Fleischmann DB BR 120 is actually quite an old model, but ran smoothly on test in the shop (on analogue DC) and it was reasonably priced, so I took a risk on it being either DCC-ready or easy to convert. On examination on the workbench, I found it was not going to be as straightforward as I had hoped, but after languishing on the workbench for a while, while I thought about what needed to be done to isolate the brushes, I bit the bullet, dismantled it and took a closer look. I had planned to drill around the screw holding the motor faceplate that grounded the left brush to the motor bogie frame, but closer inspection revealed a small tag of metal on the faceplate linking the screw part to the brush part of the circuits on the faceplate. A small drill made short work of that link!

    After desoldering and removing all of the other wires, I tested the brushes and pickups to make sure they were not connected electrically in any way. All was going to plan now. The original PCB was discarded.

    The next stage was to wire in a decoder. I chose a Lenz Standard+ decoder as being entirely suited to this job. Wiring the red and black wires to the trailing bogie pickups and the black to the small metal plate with that previously mentioned screw on the motor bogie, red to the pickups on the right-hand side (with the motor bogie trailing), completed the first bit. Orange and grey wires were connected to the brush plates on the faceplate circuit board. Another test on the programming track proved it all worked perfectly.

    I have left the wires to the directional lights unconnected at present, because I am seriously contemplating replacing them with some bicoloured LEDs. The Lenz decoder has four functions, so can be wired to power the tail lights independently of the headlights.

    Anyway, here she is: DB 120-160-7 ready for active service, although she won't meet the lighting standards for safety yet!

    I used to drive VAL's for a little known firm of Butlers in Loughborough, before moving to Howletts at Quorn very smooth riding vehicles

    My most memorable ride in a VAL was as a child on a school excursion from Crawley to Arundel Castle. The coach was a Duple bodied example in Crawley Luxury's fleet.

    My recently purchased experimental blue class 30 D5578 has found its way onto the workbench again.

    I bought it knowing that one of the side windows was missing (it was accurately portrayed in the photos on eBay), and that the buffer beam cowlings were missing as well. I got it at a bargain price, considering it was sound-fitted, being a code 3 repaint of a factory-fitted Railfreight model. This is the super-detailed model with central can motor and flywheels driving all six axles (which is actually two more driven axles than the real locomotives have!).

    The side window was reglazed with a suitable piece of clear plastic, but I will have to restore the handrail bars at some stage.

    Initially it refused to run - something was sticking in the motor or transmission, but I got that cleared. Then there was a slight clicking as it ran, but it ran smoothly enough. Subsequently, it would stop occasionally with the driven wheels slipping but two of the axles not being driven. On investigation, I found that the two inner axles (one on each bogie) had so much side-play they were going out of engagement with the rest of the drive train gears. Removing the base plates of each bogie (each has six clips retaining it) showed that for some reason, Hornby have the axle gears near on the centreline, while all of the drive train gears are off-set to one side. When the axles were moving sideways, the gears were moving just enough out of line to lose engagement. The side frames of the bogies help to locate the axles and limit the side-play, but have a tendency to bow outwards slightly towards the ends. The sideframes have spigots that go into hollow posts projecting horizontally out from the inner bogie frame.

    After some head scratching, I came up with the idea of trimming the ends off the hollow posts on one side only (the side opposite the sde the gears are on) of the main bogie frame, clipping off approximately 1mm or less from the outer ends to just close up the amount of side-play and forcing the axles over towards the gear train. I used a sprue cutter to do this.

    Pushing the sideframes back into the spigots then clipping the base plates back on also locks the sideframes into place. The slight reduction in the width between sideframes has also limited the amount of side-play in the axles and means the loco now behaves properly with no loss of drive to any of the axles.

    Edit: I should add that the buffer beam cowlings were never fitted to this model in the first place, being a modern Railfreight example. I will have to make some up, rather like I did for the Hornby RailRoad example I fitted an earlier Lima body to.
