Waiting Its Turn

Moelwyn spent the weekend in Glasgow as a static exhibit, once again, lurking at the doorway into the goods shed.

This vintage Baldwin 'tractor ' - a veteran of the First World War - is a loco we have yet to adapt for DCC control, but I'm hoping that can change in time for the next time we have the layout running in Porthmadog in May.

The difficulty is there is nowhere immediately obvious to stuff all the gubbins - the chip, stay-alive capacitor, and speaker - with it hidden from view.

At the moment most of the space inside the bonnet is taken up by the Mashima motor.

I am told that it is possible to retro-fit a very small coreless motor which will create just enough space to hide all the kit and I am seeking advice from those in the know.

The other question is what to use for a sound file.  

As well as its vintage Gardner diesel engine Moelwyn has a very distinctive, rhythmic whine from its gearbox at speed.  

Again, I have hopes that one of our friends with all the right kit will be able to assist us with this.

How useful Moelwyn will prove to be is an open question.

It's built from a Meridian etched brass kit, so it's not featherweight like a 3D print would be, but it still doesn't have the heft of a white metal casting.

What we do know is that on Dduallt it is capable of hauling a couple of carriages up the hill, which is similar to what Britomart can do, so hopefully on Minffordd it will be able to drag a couple of wagons at a time up the ramp from the depths of the yard.

Hopefully, before to long, we will be able to find out.

Short Circuits = Short Fuses

Digital Command Control - or DCC as we have all come to call it - is a wonderful thing, but let's not pretend it doesn't have a lot a downsides.

Many might regard the cost of the chips as the biggest drawback, which is especially the case when you're going for sound as well, because it can sometimes double the price of a new locomotive.

Then there's the complexity of the control handsets themselves.  

A couple of times during the Glasgow show I looked across at some of my fellow operators and saw only furious button pressing and furrowed brows, and no trains moving.....

And at exhibitions I would argue that perhaps the biggest issue is the way that everything on the layout comes to a stop as soon as anything creates a short circuit.

Mostly this is because of simple human error - a failure to check the route has been set before moving off and the loco runs towards point which are set against it.

The problem is affects everything on the system, not just the single train involved.

But as the weekend in Glasgow wore on we began noticing an increasing number of mysterious occasions where a train made up of our set of 'Barn' carriages would come to a stop in the middle of plain track for no apparent reason.


The instinctive reaction each time would be to assume a short had occurred somewhere else on the narrow gauge side of the layout.

(Minffordd is divided into two separate circuits for 009 and 00)

The fiddle yard operators, and the person on shunting duty on the remote controller at the front, would face increasingly irritable accusations and interrogation.  "Was that you, again??!"

By the Sunday afternoon it had happened so often - and there had been so many false accusations bandied about - that the finger of blame started to be pointed at the train itself.

But how?

It was Himself who did the detective work and found the culprit.

It was carriage 14 what did it!


Here's the explanation.

The wheelsets we're using on these carriages are insulated on one side only, which means that on a bogie you need to have both orientated the same way if you are not going to risk creating a short circuit,

This is especially the case when the bogie frames are brass, and the axles fit into brass bearings, because the whole bogie becomes live.

We'd taken care to ensure each bogie on the set had the wheelsets matching.   

What we hadn't done was check that every bogie on every carriage matched.

On carriage 14 we had the wheelsets in the bogies the opposite way round to the rest of the rake.

With us also using brass couplings soldered to a brass bogie, the last line of insulation defence is the paint on the couplings.

As that begins to wear and chip after 3 days of intense running at a show, snaking over crossings and into fiddle yard sidings hundreds of times, it opens up the potential for the different polarities of bogies on adjoining carriages to briefly come into contact with each other, creating the short circuit.

It's simple fix to rotate the wheelsets on the bogies on 14 to they all match now, but it shows how careful you have to be.

A Job For The Dukedog At Last

I posted in the build up to the Glasgow show about our struggles to get our Bachmann Dukedog to do any useful work  on Minffordd because it struggled with the combination of gradients and very tight curves.

You can read that post here.

The solution presented itself to me in a moment of serendipity as I wandered towards the tea and coffee room past the display of one of the second hand traders I buy from most often - The Junction Box.


There on Ian's stall, calling to me, was a Bachmann inspection saloon in crimson and cream livery, which is much more appropriate to our era than the blue/grey example we already have in our stock box.

I had intended to resist all temptations over the weekend, but this seemed like it had my name on it.

Plus, a not half an hour previously, we'd just been presented with our prize for Best In Show, so I figured I deserved to treat myself as a small reward.

I can report that the Dukedog can manage to haul this one carriage around the layout, however I doesn't have the guts to propel it up the slope into the exchange yard, slipping to a stand before it is halfway up...

That is not to say that the tinkering which Himself carried out before the show has not made some difference.

It will manage - just - to haul three Bachmann Mk1s with the weights removed in the Pwllheli direction - but going the other way it will slip to a stand when it hits the tight curve into the fiddle yard.

There is limited scope for adding more weight to this model and Himself has tried three alterations.

1) Shortening the spring above the front bogie to equalise the contact of the four coupled wheels.

2) As another means to achieve this he has added a very gentle spring between the coupling bar and the base of the tender, again to direct a downward force on the driving wheels.

3) Some very small and thin pieces of lead have been fixed to the baseplate between the driving wheels.

As you can read above, the effect has been quite minimal, but at least we've found something it can do on the layout.

Eventually I suppose we might learn how to do double-headers - or 'consists' as they insist on calling them - using our NCE handsets, but from reading the instructions that looks like a very complicated process which requires many steps to be memorised....

The Hitman And Himself

It's not false modesty when I say that no one was more surprised than I was when Minffordd was named as the winner of 'Best In Show' at Model Rail Scotland at the weekend.


I've been coming to the show at the SEC in Glasgow for nearly 35 years now - my first visit was in 1993 - and I think the quality of the layouts this year was the highest I've yet seen at the venue.

I must confess I was absent for the moment of presentation on the Saturday afternoon.  

I'd been operating for most of the day and handed over to one of our team so I could sort myself out with a cup of tea in the rest room set aside for the hundreds of volunteers who make the show happen.

I hadn't even reached the doors to the hall when my phone rang to summon me back, for what I assumed must be either to sort out a catastrophic derailment or some other kind of dreadful emergency.

As I returned I saw Himself beaming, and clutching a very heavy glass trophy!

I am sure I wasn't alone in assuming that this award - the Jim Grieve Memorial Trophy to give it its proper title - was certain to be presented to Pete Waterman's massive, and massively impressive, Making Tracks 3.


This modern image monster of Milton Keynes was no doubt the big 'must see' attraction for many of the visitors who came to the show, on its first time being displayed in Scotland.

Everything about it is remarkable, not just in terms of size, but the intensity of the operation, the number of people it takes to operate it, the vast collection of full-length trains, the standard of presentation, and perhaps most importantly, the consistent standard of scenic modelling which I have always believed is the most essential element of a good layout.

You may have some individual pieces on a layout, be they trains or scenic features, which are absolutely exquisite, but if they are very obviously of a different standard to everything else around them then it is jarring and spoils the overall effect.

The great music mogul and famous railway enthusiast - and his team of Railnuts - did not leave empty handed because Making Tracks was named Best Visiting Layout (as distinct from the exhibits from clubs who are part of the Association of Model Railway Societies in Scotland, which includes our club in Greenock, under which banner Minffordd was appearing.)

There is also a category for AMRSS exhibits, which I had dared to hope we might be a contender for one of the top three placings.

The first place for that went to Hazelbank from the Scottish Diesel and Electric Group who have a well-deserved reputation for producing top-quality modern image layouts - although I suspect I may be showing my age by categorizing the 1990s as modern.....


This is a 'what if' for what might have happened if the Waverley Route had never closed.

There were many other layouts I very much enjoyed watching, including ‘Moor of Rannoch’, a very small slice of the vast, bleak tract of land the West Highland Line passes through, cleverly using the famous snow shelter as a scenic break.



It is the essential bleakness of this layout, and the accurately-represented bleached tones of the vegetation, which make it so effective to someone who has spent time in that lonely spot while hillwalking.

It has a quite a 'Bron Hebog' feel about it, I think.  Wouldn't it be marvellous to do something like this in N gauge and with the same depth and emptiness as our layout?

OK, maybe not....

There was also a good selection of narrow gauge to be seen at the show, including a chance to be reacquainted with the Clyre Valley Railway which was a deserved prize winner at the last Warley club show at the SEC when we took Bron Hebog there as part of the anniversary celebrations for the 009 Society.



And in 7mm scale, and showing the less 'cute' side of narrow gauge railways, was a terrific representation of the industrial system around the Bowater's paper mill.

Summer Holiday Traffic

Realism on a model railway is a funny thing.

Sometimes it is possible for things to be too accurate, as strange as that may seen.

When looked at in miniature form they just seem wrong.

I was thinking about that this evening as I was placing the loose vehicles as we set up Minffordd for the Model Rail Scotland show which opens tomorrow (Friday 27th March to Sunday 29th).

In the back left hand corner of our scene is a short section of the main road into Porthmadog.

After setting out two or three of them, plus our Crosville bus heading for Blaenau, I wondered whether I'd crowded the scene a little?

And then I thought again and added as many as I could until they were nose to tail.

Because I'd remembered the hours I'd spent in a baking hot car as a child sat in traffic jam to pay the toll for crossing the Cob which often stretched all the way back to Penrhyndeudraeth - in my memory, at least.

So if visitors at the SEC this weekend engage us in conversation and feel moved to comment that there are 'too many cars on that road,' I shall feel free to contradict them.

Calm Before The Storm

I popped in at Himself's place the other day and couldn't resist taking a few phone snaps of Minffordd with the late afternoon sunshine creating an almost sunset-like effect over the layout.


All the adjustments and improvements made through the winter are complete and have been thoroughly tested, and now it's ready to be taken down, bolted to its travelling frames and taken for the short ride to the SEC in Glasgow for the Model Rail Scotland show which opens on Friday morning.

Before too long I would hope one of the magazines will arrange for a proper photographer to come and do a proper shoot which do it more justice than I can manage with an ageing iPhone.


This view, which is rather like the one you'd get standing on the roof of the down platform shelter at Minffordd, reminds me of one of the things which makes it such a different kind of narrow gauge model - the double track main line effect.


This is a very the public doesn't really get to see, and is one of those bonuses of being a layout operator. 

Unfortunately, those who are not familiar with the FR don't get to see what an attractive building the Weigh House is, only getting to see it's rather plain back wall.


For now it all looks very sleepy and abandoned, but in a couple of days the Simplex will be busily phut-phut-phutting around the yard, up and down the ramp to the 'coal hole' while mineral wagons and empty gunpowder vans are shunted along the long siding high above.


If you're able to come along to the show please say hello to the team.

For those who can't we'll do our best to share pictures and videos on our social media so if you don't already do so follow us on Facebook, Bluesky and X (the the continuation of an account does not indicate endorsement or otherwise of the proprietor....)

A Mickey Mouse Layout

 We're going try something daring in Glasgow next weekend - running a guest loco!


This is always fraught with risk, especially on a layout with extremely tight curves and using Kadee couplings where it pays to make sure everything is set to the same standards.

However, with the extra train capacity in the fiddle yard extensions, and with a question mark about the usefulness of the Dukedog, I thought it would be prudent to ask the Medical Director if he fancied bringing along his sound fitted Ivatt 2MT - a class sometimes nicknamed a Mickey Mouse, I know not why - because they were also to be found on the Cambrian at this time.

This particular engine 46334 did not work the Cambrian under BR ownership but is well known for doing so in preservation having been called to substitute for a failed Standard 4MT when steam first returned to the coast in the mid-1980s.

I expect the greatest challenge with this loco will be the Medical Director’ idiosyncratic technical set up.

In common with much of his fleet this loco operates in the reverse of what you might expect.

Select forward on the controller and the loco goes backwards, and vice versa.

Who is going to be the first among the crew to forget this minor detail?
