Studholme 10 - Cutting the cords.

DB follows on after a pause - this post has been in draft form, occasionally appended to, for the past six weeks. 

The Studholme module build has been a bit drawn out and higglety pigglety with all manner of things occurring out of the ideal sequence. Here is an attempt to get things back into a more sensible order of operations.  

Its always a good idea to paint the trackbed/scenery so if any ballast falls off there won't be white primer showing through from underneath, so this was done, as was filling in the remaining holes in the baseboard framing with foamboard. 

After these pictures, the track centrelines, obliterated by that recent application of grey paint, were redrawn.  

So finally things are at the state they should have been before any track was laid many months ago! Now feels like a good time to put down more track and start soldering it down across the PCB joins. 

As the old bomb disposal line goes: "Cut the green wire...." Snip. "But first, cut the red wire." A clever tip I picked up from somewhere was to loosen the module joining nuts a little, then place a very thin sliver of cardboard or plastic between the modules and loosely tighten everything up before the track is soldered down and cut. Then after cutting, remove the card and tighten things up to remove the Dremel-cutting-wheel-sized gap between the rail ends left from making the track cut. 

Its also quite hard to cut the track vertical because the Dremel's fat motor body is a much larger diameter than the cutting wheel. You are often left with a V shaped cut. 

Fortunately, the second-hand Dremel that I have (its a Fuller one actually) came with one of those flexi shaft extenders which has a thin endpiece you hold onto, so this makes it a little easier. 

Other approaches: 

I suppose a jeweller's saw could be used if you had the track up on a decent embankment or a really thin wooden module end.

You could also simply butt cut sections of track together and stick them down, but I figured with my module mounting pins providing a reliable location during module mating (ooo, err), tracks that are soldered across the join before cutting should all line up perfectly every time. 

As an aside, a few subtle changes and liberties have been taken with the Studholme track plan for 'model operational' reasons.

The real place had, to the east side (to the 'right' of the picture below), a main, loop, goods loop/shed road, and a loop around that goods shed that I remember being used for fresh fruit. The Froot Loop as American cereal makers might say.

On the model, I've decided to move the goods shed 'east' one track, so that gives me a main, loop, another loop, and then the goods shed. That means I'll be able to practically have four decent sized trains crossing here (including the west 'island loop')without having to run through the goods shed (which was previously, per prototype, on the long eastern goods loop) or loop around the fruit track.  I've left one stub siding in to represent that fruit track, so a Z could be parked there. I doubt that this or the goods shed little loop would ever be used much in operations, but they do have reasonable large radius points for looks.

I made some subtle changes to my plans for the west (left) side too, with a siding that will have the wagon turntable into a seed store, and the coal merchant. This leaves a runaround loop beside the island platform for Waimate branch operations. I've also included electrical breaks so the 'Waimate branch' can be run using the DCC controllers being used for the rest of the layout, or by a separate (perhaps DC) controller. The track on the west side has two switchable and isolatable 'blocks' ... so... 

• the island loop can be used by the main DCC feed for mainline crossings, while a branchline train comes into the runaround loop. 
• or the whole island loop (right down to the far end) can be used for a Waimate branch train to come in, run around and shunt (including accessing the near end of the island loop)
• or a mainline DCC goods could drop off wagons into the far tail of the island line for the Branch loco to pick up.
• or the whole thing could be run by the DCC controller so that a mainline train could shunt the coal/seed siding.

I did consider having another point off the waimate branch to serve the stock yards, but decided against putting another point there. There's not much room, but perhaps a few fake rails might be laid in the grass there and a sheep wagon plopped on them.

Seen from the other (north) end:

So there we have it. Some progress at last. 

Next, some more work on the points (three mainline points still need to be attached at the south end, plus the Waimate branch Y and curved point), some wiring, and after that (finally) the fun can start.

Christchurch Big Train Show visit

DB is barely holding the fort while Dandruff-San visits the far east.

The Christchurch Big Train Show was last weekend. There were plenty of layouts, stalls and chat to be had, so myself and a fellow modeller from Oamaru ended up staying four hours and we both had our wallets lightened by the cunning salespeople and their shiny trinklets.  

And wow! There was some unexpected (unexpected by me!) NZ120 presence there, with Ian Perry, who lives near Kaikoura, showing his model of scenes that are, unsurprisingly, from near Kaikoura. 

Rolling stock was from Trackgang, and all airbrushed - some of the most 'professional' looking finishes I've seen in NZ120. This all ran perfectly (even with multiple tracks across angled module joins) and looked great, with the scenes and bridges being great representations of either actual scenes, or of the general feel of the place. 

Ian and his wife spent a lot of time traveling around NZ in their caravan, and most of this was built during their journeys!

He had a Faller car or two running around as well to add to the interest. 

'Kaikoura' looked great,  ran flawlessly, and was the well-deserved winner of 'layout of the show'. The recabbed DGs didn't hurt either, although there was a TMS red DF there as well...

Regular S scale attendee 'One Track Minds' were there with some lovely models, although some of my favourite modules from last year were not in the layout this time.  This simple one below has nice undulation and shows that a module doesn't need to be in any way complex to be very effective.

Many of the locos on this layout had some superb sounds. The sounds for the DGs were recorded by Peter Ross when the DTG's DG 772 was undergoing load bank testing. A video may appear below if Blogger will publish it:

There were plenty of other US and European layouts and trains in S, HO, N, 009, Z and G, but I didn't end up taking many more pics.

Something that did catch my eye on local purveyor Ironhorse Hobbies' table were these 'ready to run' modules intended to jump start some local OO/HO modular efforts.  There are no legs for these yet, so you'd have to make your own.

I might be tempted to pick one or two up (sans HO track, and locating magnets in the ends) to try out as an add on to Studholme.  Especially as they are considering offering various lengths (these are 300mm x 560mm), and 'curved' and 'drop' versions so you could model a river or undulating scenery if you get bored with  modeling the Canterbury Plains in flat rectangles of land.

In a similar vein, the NZ Model Railway guild just reviewed some laser cut modules from Hamilton-based Craftmaster. Theose may be lighter (being made of thinner plywood) and fancier but I'm rarely passing Hamilton, and I expect postage might be painful. Review of Craftmaster modules

For those of us who are challenged by being located in the Mainland Island may find it easier to arrange (info@ironhorsehobbies.co.nz) to pick one of these "IHH-Trak" modules up from Ironhorse ones if they were passing Christchurch. I'm going to drop ironhorse an email to see what the go is.

An update of sorts

Theres been a bit of radio silence from La Casa Dandruff over the last couple of months. I was made redundant at the end of July (becase the Pharamaceutical industry doesn't need research scientists according to the ICE bean counters). 

Now theres a few of you that might point out that this seems to be a dream come true. I'm finding its not. a couple of hours a night modeling relaxing from a stressful job is quite nice. When theres no job, no stress and infinite time, one tends to drift somewhat. I'm still in the 5 stages of grief, but they all seem to be piling in at the same time. Plus theres a current dearth of scince jobs in this country, and I'm down to single figures for retirement which never bodes well. I got asked at a support appointment "so what do you see as your dream job". My reply was "I've just been fired from it." I suppose I could try Bunnings given I already know exactly where everything is located in their stores. A plus is that the lady of the house is currently enjoying having a "Homme d'Maison"

So tomorrow the lady of the house and I are off to Japan for 3 weeks (planned in March and a break for both of us will be nice). I hope to come back somewhat healed and releaxed as its time to find a new career.

Studholme 9 - tracking it down

 DB says:

Studholme took a pause while life got in the way again, and also because of yet another mental block: how should one affix the track at the ends? My initial intention (and implementation) was to glue it down with contact glue, and the ballast glue would further lock things in place - as it seems unlikely that this will be dismantled or set up that often. 

Or would it? There would be nothing worse than showing up at an exhibition to find the track had been banged up. 

So I thought for a few weeks about soldering each rail to a brass screw and eventually decided to use the old PCB method, even though its a bit ugly. I still have one little rectangle of PCB left over from Otaki (!), but fortunately Jaycar still sells this stuff.

So let the next round of trials and tribulations commence. The first challenge is to cut the big square of PCB into more useful strips of the stuff. I vaguely remember scoring this in the past with a Stanley knife (a million times) and then snapping it off. I think Rhys said this stuff isn't great to power-saw because of the dust.

With the help of a few C clamps and some bits of wood I was able to snap off a few sections about 1 cm wide. A few some strips were then prepared for the first module join to be tackled, and the plastic flextrack sleepers cut away. This was challenging as I'd already glued the track down on this module end, and its always more fun on code 80 Peco track due to the way the lower half of the rail it set into the plastic sleepers. In addition, the PCB is slightly thicker than it should be, but I'm not going to let that bother me. In fact I liked the little undulations as the trains moved through Otaki.

I held the strips up to the track layout and marked the length and where I'd drill and countersink screw holes to fix them to the modules, and cut shallow insulation gaps through the copper with a razor saw.

And then screwed them down...

The near ones were subsequently removed and the holes countersunk a little deeper to hide the screw heads more. I hope ballast will cover the rest - I'm sure I did a worse job on Otaki.  Note the cardboard slivers between the modules in the above pic, we'll come back to them in the next issue.

This post was supposed to end with the joins all soldered up complete and cut, but this has been weeks in the making already, so I'll leave the soldering for now and get this posted. 

The final thing I did today though was to fill all the screw holes and paint the fascia. I went down to Mitre 10 looking for the Resene 'Bokara grey' recommended in the NZ120 Fremo specs and found two test pots, but that's $12 for 120 mls of paint. That won't last long. I then remembered we had some Friars Grey left over from roofing jobs. When I got home I also found we had some non-roofing interior paint in a similar shade so decided to use that instead. Its obviously a slightly different shade to Bokara, but I decided to waste that $12 on coffee and a scone tomorrow instead.

Will give it a second coat tomorrow. 

Turning CBs into coal wagons

DB says:

So excited was I at the rapid progress made in coaling up the CWs that a return visit was made to the dungeon to do the same with the CBs. 

All the CBs had thin card false floors fitted a dozen years or more ago, which were of various degrees of coal-tightness, but the gaps were easily plugged with dollops of PVA. One had been topped with an experimental application of builders expanding insulation foam, but that was a bit of a disaster as it takes some practice to tell how much - or more correctly, how little - needs to be added as it keeps growing for some time after you squirt it into place. This was largely cut away with minimal damage to the wagon.

Those cross braces between the hungry boards were an inspired decision many years ago, as they look pretty neat with coal across them.

While on a roll, I painted the CE, CW and CB Microtrains copper-coloured brakehoses, touched up any chips and scratches accumulated in the last decade, greyed up the CW bogies to match the other wagons, put an additional bit of panel wash weathering onto the CWs and considered a few other improvements. 

So that's 17 wagons for a decent coal train from 2005-2013, which covers the Tranz Rail blue through black, through Toll through KiwiRail period - dated from when the CWs got hungry boards until their demise. I think the red non-chuted DXs were probably gone off the coal trains by 2005 unless in use as an uphill leader through the tunnel as non chuted leaders on the eastbounds were still allowed then? A few more CEs and CBs instead of the CWs and the train would work up to the present time. 

Turning CWs into coal wagons

 DB says:

Ah returning from the madness, I decide to give myself a day off. And as I haven't done any modeling for a while I decided to treat myself to a visit to the dungeon and tackle a quick and easy win if I could find one on the to-do pile.

Since I'd had some fun with CE coal hopper recently, I thought I might put some coal in my CWs, which are stil unfinished 15 years later...

Out they came. These are fairly light, but are weighted at the bottom, and as they are multi-piece castings, they have a nice smooth rectangular hole inside that would suit the false coal-floor which I'd never gotten around to doing..

A few strips of styrene were cut and contact glued inside.

Then 6 false floors were cut to approx the right size and fettled as necessary. Only one of these wagons has any bowing in the sides which is pretty good after all this time. Coal was then sprinkled on and stuck in place (the same overchunky Peco stuff used in the CEs as I haven't gotten around to crushing any of it up into a finer grade). 

Not bad for an hour's work. One of these days they'll get some better numbers and their Microtrains orange brake hoses painted black. I think the bowed one is bottom-left in the pic above, but accentuated by the phone's wide angle lens.

By the way, I still have a bunch of spare CW parts (15 sides and 13 ends) that I'm unlikely to ever use, so if anyone wanted to donate a tenner for postage you could make up six or seven of these unfine wagons for yourself.

SI NZ120ers: Chch Train Show next year

 DB wonders out loud (and not having thought this through):

I can't be the only dude sitting at home with no layout but would love to run some trains... 

Are there many active (or potentially activate-able) NZ120 modellers in the South Island?

The reason for asking is that Christchurch has a pretty big train show each year, and unfortunately, as we don't have a Trackgang layout handy down here*, maybe we could make an NZ120 modular layout for me to run my big coal train on? 

Obviously its too late for 2024's show coming up in October, but if there was any interest, it's something we could target for next year.

This would give interested folks a year to knock a module together and scenic it, and in 8-9 months, if enough progress has been made, we could make a plan for how it could be physically set up, and then apply for a spot on the floor.

The October 2025 show gives some impetus to do that on a relatively grand scale, and a deadline to work towards to make it happen. 

My thoughts are a layout with modules based on the Fremo120 standards for new builds, although I see no reason why MMW modules and almost any other existing module couldn't be attached in some temporary but reliable fashion** to join in:  

• DCC. Possibly with a straight DC operable branch hanging off Studholme if folks want to run DC trains) Or vice versa if DC participants outnumber DCC folks.
• 1200mm track height from floor
• Assuming there are not enough curves to make a traditional 'loop' roundy-round, we could have a long string of modules with a balloon loop at each end. I've started planning and procurement for one balloon end.
• All NZR eras/periods/epochs, diesel/steam/electric and geographies would be welcome.
• No TGV's please - slow to medium speed operation to... minimise derailments, respect other people's rolling stock and modules, and for a better look. 

During show hours, the layout is "for the punters not the operators" ...i.e. 

• Layout is set up and tested before the doors open rather than spending the first two hours having the public watch you building things and trying to figure out how to get a train to run. 
• During the open hours, there's always stuff going on, ideally a variety of different trains, train crossings, maybe the branchline is working or shunting, but there is always something running for the paying public to look at. 
• Minimal fuddling around (i.e. if there is any shunting, it shouldn't tie up the mainline).
• Using the most reliable stock (things that derail or don't run well get fixed, get cleaned or get relegated to the sidings)
• We fix problems and derailments quickly and get things moving again.
• It should be realistic, impressive, and show off NZ120's potential so more people join us for the next show. 

Then:

• We can play with the derailing trains, complicated shunting with timetables and car cards after the punters have left. Or on the branchline if there is one and there are plenty of operators. But ideally over a few ciders after the doors close. 

So ... I have Studholme slowly under construction (3.6m) and have plans for two more modules to match it (one plain Canterbury Plains flatland, and a similar one with a low bridge which might be a curved module). So that could be 6m of modules to start with. Plus my balloon loop.

Ideally there would be another few "single track open mainline" modules. Maybe some have a culvert, or a road crossing, or a curve, or a bridge, or a tunnel or a cutting or an embankment. There might be a few 45 or 90 degree curve modules for variety (or if we end up growing too long for the space available). 

Perhaps someone might build two or three of these as a Module Set for scenic consistency. 

And the other balloon loop. 

If we had enough "open space mainline modules", perhaps someone might make another small passing loop station (Staircase, Seacliff, Tawhai, Kekerengu...). 

Sooooooo...... Is anybody out there interested in coming to Chch in 2025 to run some trains on a decent sized layout and have a few laughs?   And would you be interested in building a module or more?
