Progress update

Haven't had many opportunities to get up in the loft recently, plus it's quite chilly up there.

The eBay purchases arrived, one of which, although advertised as spares or repair, does actually run. Haven't spent much time on these yet, still looking at the best way to convert the 0-6-0s to three rail running. Not sure if it's easier to use Marklin skates or Dublo ones.

Meanwhile I've now laid 2 running loops and down one side of the layout these run into four, with an additional fifth centre line which I will leave for further expansion at a later date. I also added more sidings and started building my terminus, firstly checking that the locos could enter an exit without stalling or derailing. So far, the Deltic, Diesel Shunter, 0-6-2 tanks, 2-6-4 tanks, 8f and even the Bachmann EPB have all managed to exit the terminus, run round the outer loop and back into the terminus again without fault so I'm happy!

There are no diagrams of the proposed layout, although I consider myself to be reasonably pc literate I find it easier to just loose-lay the tracks on the boards. I decided to use a mixture of manual and electric points, the ones near by will be easier to leave manual - less wiring, less modifying, less hassle!

Still plenty of work to do but with the weather chilling off and Xmas fast approaching I don't envisage much more progress in coming weeks...

New additions...

Transplanted one of the Co-Co chassis from the job lot of "interesting" conversions back into a proper deltic body, this means I now have 3 operational deltics!

Ordered some ringfield neo magnets and once these arrive I'll do a motor swap with the noisy Co-Bo Metrovick.


I've also snapped up a rather nice looking 0-6-0 steam loco and have another on watch, both non-runners. I've never seen one of these close up and it will be interesting to see firstly why they're not working and then see how easy they are to convert to 3 rail running. I'm not aware that Dublo ever made these in 3 rail, hopefully I can use the pickups that will be left over from the redundant deltic chassis once  I've pinched the motor out of it for the Metrovick! The 0-6-0 only cost £16 so would be nice to get it running.


Elsewhere in the loft I've made a start on clearing space for further track laying and decided to abandon my idea of 4 loops in favour of 2, this will make the layout far less complicated and reduce the number of diamond crossovers. Also if I'd gone with 4 tracks I would have ended up installing points in locations that aren't easily accessible, so these sections can be left with just straight sections of track. I've mocked up a great idea for a terminus and some extra sidings. I don't tend to draw these things or use planning software, just gold old fashioned track laying.
I've now sold all the DCC controllers, booster and the decoders I'd removed from the locos, along with the decoders that were still in their packaging. Very pleased with the amount of money raised, I managed to make a small profit on the select and the elite as these were second hand purchases. I did of course lose out with the decoders and the power booster but with Christmas fast approaching, every little helps...

Pictures from 3 & 4 November weekend

Old & new - the Bachmann 2EPB ran faultlessly all weekend. Here it's lined up next to the Dublo SR EMU, with Dorchester to the left, next to that Bo-Bo D8000 waits to leave with a goods train, Bristol Castle heads up the TPO coaches and finally the Bachmann 4CEP is in the background.

The road to the far right is way too close to the edge of the board and will be removed before the next run.

Dorchester waiting to take power

Dorchester from the other side of the tracks, the back of the goods train and TPO set also visible, although the goods train had shed its guards van!

Rear view of the Bachmann 4CEP

Same location. The road the CEP is parked in turned out to be practically un-usable due to too may twists & turns entering and exiting so a revamp is needed.

Waiting for a clear signal

Illuminated and ready to go

The sidings and turntable, with newly streamlined entry avoiding some of the twists & turns that had been installed previously. Sadly the girder bridge didn't arrive in time, which resulted in the piece of track in the foreground crossing the two board sections unsupported.

The far right track section has now been removed along with the crossovers and several sets of points. The twin curves will simply shift over to the left by 1 track and turn what is currently a long siding into the inside running loop, with the current inside loop becoming the outside loop (make sense?)

The many points and crossovers proved problematic, there are more points and crossovers installed further down on this section and derailments / stalling were common, even with proper Dublo stock.

Lined up in the sidings - Diesel shunter, 0-6-2 shunter, Bachmann class 25, Cardiff Castle (with broken coupling) and 8F 
Zoomed out view, with the non-functioning Co-Bo

Main station layout again - 6 roads but will be streamlined shortly

DCC Conversion - How I converted a Ringfield motor

**Disclaimer** I am in no way a professional and accept no responsibility for anyone who chooses to follow this guide or trashes their beloved pride & joy by following the steps below. This isn't published as a guide, it's purely to show how I converted the loco for DCC operation.

The Ringfield motor can be found in later 8F's, Castles, Westcountry class and many Wrenn 2 rail locos, as well as my little diesel shunter here.

You will have to drill out the end cap of the motor to convert a Ringfield motor to DCC. You will also need a decent soldering iron. Mine is 60w - I found that the cheaper soldering irons aren't man enough for some of the dublo soldering jobs.

So this is how I converted my diesel shunter, with Ringfield motor, to DCC:

Diesel Shunter, casing screw removed, ready for dismantling
With the casing removed, it's time to remove the electrics & brush springs, followed by the 4 retaining screws that secure the motor end cap to the chassis - I've also removed the motor bearing to avoid any metal filings ending up inside the bearing when I drill the end casing later...

Motor end ready for removal

Now with the end cap removed from the chassis, the un-insulated brush holder needs to be removed...

End cap removed
I use a brush holder plug from a scrap Dublo loco to carefully push out the brush holder, using a pair of long-nose pliers...

Dublo brush plug inserted into the brush holder from inside, ready to push out the holder

...And it pops out quite easily...


Brush holder removed, undamaged so it can be re-used!

This is the point of no return, so unless you're 100% certain that you want to convert then STOP NOW!



In the vice, ready for drilling

I used a 6mm drill bit to enlarge the hole ready for the new insulator...


New insulator, sourced from the internet

Once drilled, I carefully press the insulator into the end cap...


Insulator fitted

I then need to refit the brush holder, I used the vice to do this bit, slowly & carefully pressing the holder into the insulator...

Pressing the brush holder back into place

Voila!

Perfect!

At this point I test to make sure that both brush holders are electrically isolated before I refit to the chassis & fit the brushes...
There should be no resistance between the brush holders & casing, if there are then remedy this before proceeding any further.

I've now re-assembled the motor, brushes and retaining springs, time to check again for resistance to earth...



Before fitting the DCC decoder, I decided to run the loco on DC to ensure smooth running. A neo magnet has already been installed and as I previously removed the end bearing, I need to ensure that it's correctly adjusted. If the bearing is too tight then not only will the motor not run properly, it will also draw more current, potentially damaging the new decoder...


A rather crude method of testing the loco on DC prior to installing the decoder.

I'm satisfied that all is well so now it's time to install the decoder - This is where a good quality, high temperature soldering iron is a must, the connections to the brush holders need to be done quickly so as not to melt the plastic insulators.

Also worth noting that I've removed all traces of the original electrics. 1 of the 4 end cap retaining screws is also used to earth the brush spring to the chassis via a metal strip (in the below pic it would be the top right screw) which can easily be seen once all 4 screws are removed. This is discarded prior to re-assembly.


The decoder soldered in. I only need 4 wires so the remaining wires are cropped and secured inside heat shrink, just in case I want them in future.

Re-assembled and ready to be programmed. At the moment I haven't set up a proper programming track so for writing the loco address I use the Select controller as there's no need to keep swapping the wires!

When I come to checking the CV's I'll use the Elite controller.


Ready to go!

So after a quick blast round the loop, time for a little slow shunt...



Space is very tight in the diesel shunter, the chip is a very snug fit and has resulted in the case not fitting as flush as it did, I can live with it but purists may not be entirely happy, however a purist would probably have left it on DC!

And in the beginning...

**UPDATED July 2015**



Post number 1 - a brief history of what I'm doing, how, why and where etc...

My "little" Dublo obsession began as a child - although I was born long after the demise of Hornby Dublo my brother was given a generous collection of old Hornby Dublo 3 rail track and rolling stock by our Uncle, which as the annoying younger brother I also got to play with. We did also have some 2 rail Triang kit and some rather nice boxed Wrenn locos - Dorchester & Cardiff Castle. I never saw Cardiff Castle run for more than a few feet at a time (the reason for which I would later resolve some 25 years later!) so the 3 rail stuff got more use, plus there was more track so more possibilities for layout designs.

Our Dublo collection consisted of the two popular locos, Duchess of Montrose and a 2-6-4 tank engine, most likely an 80054, a TPO set and a generous amount of track, coaches and wagons. More than enough for hours of entertainment.

Like everyone else, my brother and I grew up, our fondness for playing with model trains evaporated as we got older, left home, discovered girls and got married. The exact whereabouts of our old Dublo train set is still not entirely known but was most likely thrown away when my parents down-sized. All that remained were the two Wrenn locomotives, still in their boxes. The Dorchester had long since lost its front bogie due to constant derailments, so it was removed. The Cardiff Castle was more or less intact, mainly because it had never run properly. However both locos were complete non-runners, which was entirely my fault.

As a kid I had a passion for taking things to pieces - a bit of a quest for knowledge to see how things work etc, but the main reason why the two Wrenn locos were non-runners was because as a child I had taken both of them apart in a (futile) attempt to convert them to three rail running, using the only resources available to me at the time - namely a track pick up from a TCR (remember them?) racing car and of course Blu Tac! Needless to say my early attempts at three-railing failed dismally!

About seven years ago, I was at home, bored and surfing Ebay for various items. Out of curiosity I searched for Hornby Dublo and was surprised that there was still so much of it being offered for sale - and some eye-watering prices for some of the items being sold. I then happened to mention to my Mum that I had been looking and actually quite fancied collecting some Dublo again. Initially all I wanted to do was try to get back what we had as kids - a Duchess of Montrose and maybe a 80054 again, plus some track.

Some weeks later my Mum visited me and gave me a few presents - first she presented me with a small oval of three rail track that she had bought from a toy fair and then gave me the two boxed Wrenn locomotives (the ones I had trashed years earlier) at this time I hadn't known that they still existed and my Mum was unaware of their non-running state!

So I had track, two locos (which didn't run) and no power supply - but it was a start...

Several weeks later and after attending a toy fair I had acquired a Marshall power controller and my Mum presented me with a refurbished Duchess of Montrose, Finally I had something to run and I was in business!

So now I wanted to revisit the two Wrenn locos, either to repair them and restore them to their original two rail operation, or complete what I started all that time ago. I went back to Ebay and found a scrap 80054. My thinking was that all I really wanted was the third rail pick up to transplant into the Wrenn Dorchester and complete the conversion. I ended up paying £13 for the 80054 and when I took it to pieces, I realised how simple these old locos are. All it actually needed was a clean up and a new magnet (which I sourced from Ebay) and it was up and running again. Brilliant - I'd just fixed my first loco and brought something back to life, something I'd never managed as a kid!!!

Dorchester eventually got a proper three rail pick up after visiting another toy fair and that was soon returned to running operation - another major achievement given my total failure so many years ago. Cardiff Castle at first was more of a challenge, mainly because I hadn't worked out what the two holes in the tender were designed for! After some more head scratching, Ebay and Google searching I had my answers, and the plunger pick ups to convert properly.

And the reason for the poor running all those years ago... the screw that held the motor to the chassis was missing!

So now I had four running locos - three of which I had brought back from the dead with very little knowledge or experience. I couldn't afford boxed pristine "as new" items and so I decided that if I was going to collect more items then unless they were given to me as presents then the way for me to go was to buy play-worn / scrap / spares or repairs items only and fix them up as best as possible.

And that was the beginning of my Obsession with Dublo - there is nothing quite like the sight, sound and smell of a 50+ year old loco thundering off down the track at full pelt. Even more satisfying when the loco is something that would otherwise have been scrapped, stripped for spares or thrown away. I decided that from now on I would start collecting as many items as I could and maybe in future sell on some of the repaired items - to date I haven't sold one single item of Dublo and have most examples of their locomotives.

I briefly experimented with DCC and managed to convert most of the locos that I owned at the time to DCC operation. Sadly there were too many issues and far too many blown up decoders to justify continuation of the project, so it was quickly abandoned and reverted to DC. But I did at least prove that it can be done!

As my collection grew, so did my layout. It ended up on boards and at 10ft x 16ft was too big for our modest two bedroom semi. As a result it saw life barely two to three times a year when my Mum would hire a local community hall. After a house move I had initially planned to build a new loft layout. But then there was a distraction...

The first layout and inspiration for "I 'ad that" - This was the last public appearance of the layout in September 2013. The layout suffered damage during the 2013/14 winter storms and was dismantled in March 2014.
The portable layout began to attract more and more attention and it wasn't long before I had an offer to exhibit at a public exhibition. Two years later and the layout was exhibited again, followed by more requests to show the layout in public. By this time the original 10ft x 16ft centre-operated layout was deteriorating - it wasn't built to exhibit, the tracks ran dangerously close to the board edges, meaning that derailments could be very costly. Also the boards were of a very basic construction and had started to warp very badly. The winter storms of 2013/14 also took their toll and hastened the decision to replace it with something a little more robust.

A solution was required and came in the form of a completely new, re-designed layout that would be based not only on a wish list of things I wanted to see in a new layout, but from all of the learnings gained from the first one. In March 2014, the first design of "I 'ad that" was drawn up and construction began on a new, scenic model railway to be ready by November 2014. We had the layout ready to show by August after hundreds of man hours!

The layout practically named itself - most of the people who got to see the first layout would often just point and say "I 'ad that!"

This blog was designed as a permanent record of my loco repairs and restorations, and the subsequent building of "I 'ad that"

I will post my progress on this blog, along with any interesting articles I can think of.
