More Layout Planning

Whilst I had plans of wiring up the Sunnybank section of the layout this week, I have not got down to the shed to do anything on that project this last week.  With the various storms and rain events early in the week, I just never got to the shed.  So this has now been pushed back as a task to be completed this coming week.

Tuesday we had a great turn out at Glen’s place for our Tuesday Nighter’s get together.  We watched his favourite 81 class locos circulating around the layout, as well as an 8 car electric.  We then adjourned to Glen’s front veranda and sat in the cool night air and watched the mandatory storm coming from the west get closer and closer.  We all hit the road as it came closer and I got home just before the storm hit.  However while I was there I was talking to Bob about Arduinos and adding additional addressable ports for my signalling.  He had a device that added 16 ports to an Arduino.  So I asked Bob to send me some sample code that allows us to access those extra ports.  I looked at using this instead of using 3 Arduino Megas for my signalling with the three Arduinos all locked together for inputs from the control panel and the layout.  When the sample code came through I did not understand everything in it.  Maybe I need to go back to introduction to programming, or my throw my newly finished IT graduate son at it.  He might get it more than me.  However with a few texts back and forth with Bob, we arranged to meet up at his place on Sunday and now I have a whole new understanding of how this will work.  Bob loaned me one of these extension boards and I will spend some time next week trying to get it to work with my Arduino Mega.  If I can get one or two LEDs working, that will be it, and I will order 5 more boards, and replace the one that Bob loaned me, and continue connecting up 3 of these devices to my Arduino Mega.  This will also work out a cheaper solution.

While the boss was out on Wednesday I unrolled the paper track plan for my future exhibition layout.  It went down the hall and I worked on throwing lengths of flex track, and various points that I already had in my kit bag onto the paper schematic to see how it looked.  I adjusted the locations of some of the trackage by an inch or two here and there, in order to make it look like it was flowing and everything fitted in.  I have worked out where the baseboard joints should be.  At this stage I have 3 x 2.4m modules and 1 x 1.2m module for the front of the layout.  I will be designing the next module or two that fits in behind the front modules or Tuesday or Wednesday this week when the boss is out and I won’t get in trouble for having stuff scattered all over the floor, creating a tripping hazard.  This next module is where all the sidings will be incorporated on the layout.

This shot is where the sidings have a run around and the two main lines UP and DOWN have no track laid down for them as yet.

On Thursday I reserved an amount of 12mm track for today’s Buy and Sell.  I also arranged for a 12mm turntable for PK at the same time.  I went to the rooftop drinks on Friday and then to Shephen’s retirement drinks.  I think we will be convincing him to join our rooftop group next year.

Saturday was another full on train day.  I had to drop some fence posts off at Geoff’s work before he went home, and then went to an Operating Session at Anthony’s place.  This was a great time, as usual.  His staff machines really blow me away.  The layout runs well.  paperwork is excellent and the attendees are fun too, even if they go down the wrong tracks hey Iain?  However, some of the shunting required really tests your grey matter.

Today I went to the Buy and Sell and picked up 25 sets of 12mm points, and 8 sets of 16.5mm points.  I also scored 84 insulated joiners and a dozen lengths of 12mm flex track.  The cupboard continues to be stocked for the day when I hit the go button on the layout.

Sunnybank Progress Resumes

I think it was Monday this week that I went to the local hobby shop.  I picked up two Tillig crossovers (standard to narrow gauge) as I thought if I don’t buy them now they will be dearer when I do get around to buying them.  I was also looking at picking up some narrow gauge cross overs that I need for my storage yard out the back of the layout.  There were none in the shop on the racks.  But while walking around the shop, on top of a cabinet I found two 12mm crossovers.  No doubt someone was going to buy them and then saw some TT gauge track and bought them instead and left the Peco 12mm crossings on the cabinet.  So I bought them as well.  So my boarding of items for the future exhibition layout has begun. 

On Tuesday evening we all got online with the Tuesday Nighters and I showed off some historical photos from my future layout location.  I think I had everyone’s interest.  It was amazing that some photos showed that there were three standard gauge locos in the sidings, and there were plenty of narrow gauge locos on both Up and Down tracks, running wrong road and also in the sidings and on the branch as well.  I think this layout is going to turn heads.  Well, isn’t every layout owner hoping to do that with their exhibition layout?  I just need approval from the financial controller.  I might have to sell my left one in order to gain approval.

On late Wednesday morning I drove to PK’s and picked up his dual gauge Fast Track jigs.  I also picked up four lengths of code 75 rail.  Upon return home after 1:00pm and then having some lunch, I got stuck into building a set of dual gauge points.  By the late afternoon, I had completed the first dual gauge set of points for the standard gauge tracks to branch from the dual gauge to the sidings.  Initial testing has everything working well.  I plan on visiting PK again to return the jigs, but also use his silver solder on my point’s actuation bar, so it is currently unsoldered on this dual gauge point.  On Wednesday evening I cut up the PC board sleepers and some lengths of rail, so that on Thursday morning I could build another set of points, well actually it was a splitter piece of track where the two gauges, standard and narrow, will merge for a siding under a gantry crane.  This also turned out pretty good.  Initial testing has it working well.  It has no moving point blades.

My intention is to actually have a travelling crane on the future exhibition layout location that will move up and down the siding.  I was thinking that I need to build myself some 12mm catch points, one for the siding, and one for the branch line, given that these are not commercially available.  So I built these either side of dinner.  I then half built two 16.5mm (HO) catch points, but I ran out of code 75 rail.  I had a scout around the shed as I thought I had a length somewhere.   I found some small off cut lengths of Peco 12mm track, that I used to finish the build of the 16.5mm catch points.  One of the pieces of rail that I found, was weathered rail.  Boy, did that cause me some issues with soldering it to my PC board sleepers.  So I removed the weathered rail and replaced it with another length of unweathered code 75 rail.  I was quite happy again with how these four pieces of track turned out.  The collection of track for the new layouts continues to accrue.

The dual gauge point to go into the dual gauge with a standard gauge exit into the sidings.

In the sidings, the narrow and standard gauge lines come together under a couple of gantry cranes.

The various catch points, the two narrow gauge ones on the left and the two standard gauge ones on the right.

Eventually I will need to schedule another trip over to the other side of the world to get about four more lengths of code 75 rail from PK.  These will be put aside for the rails needed for the travelling crane or should I say travelling cranes, to run on as there are actually two on that track in the prototype’s yard.

I did some stocktaking of track components and worked out what types and how many I need of the various sets of points in 16.5mm and 12mm gauges.  I hope to get my first drawdown from the boss and go looking for points and narrow gauge track at next Sunday’s Buy and Sell in Brisbane.

Today really early, my son’s mates all rocked up at 6:35am, before they took off on a road trip to Canberra and then Melbourne and back over the next week.  But it was revealed to them by another of my son’s mates that I had a Shed in the back yard full of trains and they all want to view the layout before they hit the road.  They were enlightened and slightly overawed, I think.  But they needed to not spend too much time there as they needed to hit the road in their convoy travelling south in order to get to Canberra tonight. 

Just before lunch today I finally bit the bullet and continued on working on the supports for the trackwork from Rocklea Siding to Sunnybank Station.  I installed about 5 supports and joined all the 12mm track up.  So things are progressing.  I will be looking at installing power to this section of track in the coming week and I hope to have trains operating under their own power before next weekend.

Thinking About Signalling

Monday was the day that started to go down a bit of a rabbit hole.  I started thinking about the signalling system for my future exhibition layout.  I will have working signals that run either automatically as a train runs around the layout or with the help of a signalman who can set up cross track moves etc., into the sidings, or onto the branch.  I have drawn up a track schematic.  I started with the code for one of the tracks – the UP Line.  But overnight I had a think.  On Tuesday I changed my whole logic process and by the afternoon I had a working model running on my Arduino for the UP and DOWN tracks. 

On Wednesday I added the signals coming out of the siding and started on the tracks for the dual gauge branch line.  Also on Wednesday a new Arduino Mega arrived in the post after I purchased it on last Sunday night.  I think I will have one of these controlling each of the tracks, UP, DOWN and Dual Gauge, with the same code running in each Arduino just so I can control all the signals and the various inputs from the track sensors, detecting trains and points and also from the switches on the signalman’s control panel.  I will work to develop this over the next few months.  I will also use CAT5 cables to go from the signalman’s panel to each of the signals.  Each signal location will have at least 2 aspects, mostly 3, as well as an infrared track detector to detect passing trains.  Some shunting moves and branch line moves will also have call on signals, or junction indicators.  So this will be really cool if I can get it to work, and it will also mimic all signals on the signalman’s panel.  So the public can sit behind him and watch it all unfold, or even if the layout is automatic mode, the signals on this panel will also change as trains move through the various tracks.  I am also thinking if I need a communications mechanism from the signalman to the train drivers.  Do we just call out, use walkie talkies, use a headset system like I do at home, or use Zello on the mobile phone.  I will discuss this with my future crew.  The layout may still be two years off building, but it will have quite a lot of features that rarely exist on layouts on the exhibition layout scene.

I continued work on the Dual Gauge track signal code on Thursday and this is complete except for the signalling into the Sidings across all the narrow gauge tracks.  That is quite complex, but not too difficult.  I just need to find time and this will most likely be early next week.  My next task is to build a small mock-up of the signalman’s panel and have the track detectors simulated by hand and see the control panel show the signal aspects.  I need to buy a few red, yellow and green LEDs to replicate the signal aspects on my signalman’s panel for this to happen.  I also need to do a couple of tests.

On Tuesday we went to Cliff’s place for our Tuesday Nighter’s meeting and ran into Ian Phermister from Coffs Harbour way, who happened to be up on the Gold Coast with his family having a holiday.  It was good catching up.  At this meeting I also spoke to Brendan, our solderer extraordinaire, who gave me confidence to work on my PROCAB-R radio board upgrade.  I had an old POWERCAB throttle which I was to install a radio board into – removed from a CAB04.  But the POWERCAB did not have a 9-pin JST plug on its motherboard.  So I had to solder the 9 wires from a connection to the 9 little tabs on the motherboard.  Well this initially worked, but I needed some battery terminals to be installed into the POWERCAB case to make it all come together.  I picked up some terminals from Marcus when in Sydney at the Rosehill Exhibition, and also picked up a 9-pin JST socket to go into a future PROCAB throttle if I ever get another one.  But as I was installing the battery components, the wires ripped off from my soldering on the motherboard.  Brendan told me to clean that up and install the 9 pin JST socket.  Well I gave it a go on Wednesday, and to my amazement, after testing the POWERCAB, after removing my soldering, and after soldering in the JST-socket, and after installing the batteries in the compartment, it all worked, as both a normal POWERCAB, or as a radio PROCAB-R.  I amazed myself.

Also on Wednesday I decided to actually code up the various configurations in the chip for my 2000 class railmotor passenger car.  I set up the headlight to dim on F4.  Also moved the rear headlight which was connected to the rear red marker lights to be on F3 instead of F0R.  I also set up the front white marker lights F1, and front red marker lights and the rear marker lights F3 to all be dimmed on F8.  I gave it a test and was very happy, although the front headlights are way too bright.

I had a phone call from Barnacle Bob during the week and went over to his place on Thursday to assist with building a chassis for his 3D printed 1900 Class QR Railmotor.  He has some Halling bogies to use.  Bob was worried with his brass baseplate shorting out his Halling bogies as the railmotor travels along the track.  I brought along some 2mm styrene and showed him one possible method of building a baseplate that fits inside the railmotor shell and the bogies are attached to the baseplate with some bogie clips made from styrene.  So in under an hour we had the baseplate built, the bogies attached, and the railmotor running up and down a short piece of track powered by a 9V battery placed across the rails.  So that was version 1 of the baseplate.  All it needs is a couple of pieces of lead above the power bogie.  I’m sure Bob will refine this initial baseplate and bogie clips for the bogie mechanism and build his version 2.  It will be very nice indeed once the model is painted up and running on Mosquito Creek.

Friday’s job was to complete 2000 Class luggage compartment railcar with the installation of all its lights.  The headlight and front white and red marker lights were pretty simple, but I cannot get the rear marker lights to light.  I must have a dry solder joint somewhere or I installed one of the red marker light LEDs back to front.  I will revisit on Monday next week.  The plan was to take the two railmotor models to the Show and Tell section at our NMRA meeting on Saturday of which I did.

Mostly Railmotor Related

On Monday afternoon, I went to my local DULUX paint place and spoke to Geoff about spray cans of Silver paint for my Far North Models QR 2000 Class railmotors.  I picked up a can of recommended paint.  When I got home, I sprayed the railmotor shells with some testers white primer.  That was to seal the shells before I hit them with the silver paint.  I gave them two coats on the outside and them focused another coat on the inside of the shells just to be sure.  I let it dry overnight.

PK also emailed advising that our shared delivery of the CCH prairie wagons from CGL had arrived.  I told PK that I will collect mine on Friday when we go for a trip around the QR Brisbane network for $0.50.

So on Tuesday I hit both the shells with the silver paint.  I let them dry and had a bit of a viewing a couple of hours later.  I thought I might have been a bit light with the silver paint along the bottom of the shells, so I gave them both another light spray in that area and then put them to bed overnight to dry.

On Wednesday morning the job was to install all the LEDs required for the QR 2000 Class passenger car railcar.  That went along quite easily until at one point when testing an LED, when I applied a 9V battery to an LED (instead of my 2 x AA – 3V battery) and it went POP.  Bugger.  I was then one LED short for the guard's luggage railcar.  But PK came to the rescue as he lent me one, while I placed an order for another 30 white 0402 LEDs.  So once all the LEDs were installed, the wires connected to the decoder and the railmotor assembled, the railmotor was placed on the track and the lights were tested.  They worked great.  Maybe some are slightly a bit bright, but I can fix that later. 

Thursday was the day to install the LEDs into the Guards Baggage railcar.  Well all but one light to a marker light.  I took my 3 railmotors to the Club on Saturday to show off.  I showed them on the club layout, but just ran them on the Powercab test track.  The common comment was that the marker lights were too bright.  I will try replacing the 4.7K ohm resistor with an 8.2K resistor to reduce the light intensity on Monday or Tuesday this week.  While at the Club, Guy showed off his almost completed 3D print of a 2000 Class railmotor.  He also advised that the 2050 class railmotor was ready to print.  So early next year we will get his version.  There are a few of us lined up to get them and put them on the track.  They come with two different types of bogie mounts.  One for my Halling 12mm bogies from Austria, and another for some locally made bogies.  I still like my version from Austria, but they are not cheap, but postage is better when you make a bulk order.  I think I will need to place an order for another 12 pairs of power bogies and 12 pairs of dummy bogies before Christmas, so we are all ready for the new year when these railmotors are released.

I met up with PK on Friday, picked up my CCH wagons and the LED.  We also arrange to meet Arthur and Kevin at Roma Street Station and we caught a train to Doomben followed by a walk to a nearby Bowls Club.  Coffee and Caramel Slice for $7.50 was great.  We jumped back on the train and we went to Bowen Hills.  There we were sent into platform 3 – instead of platform 1, no doubt due to a points failure.  But our Ferny Grove train was sitting on platform 2.  As we had to ascended the stairs walk across the walkway and back down to the other platform.  As we were doing this, the train whistled out.  Bugger.  We had to wait for another 15 minutes!  I think Sparkles planned that.  We had lunch at the Ferny Grove Tavern and got free coffee and cake with the meal.  Boy were we full!  Back to the station, caught the train to Bowen Hills where PK alighted and the south siders continued to Sunnybank, where Authur left, I left at Altandi and Kevin got off at Kuraby.  All this for a total of $1.00 travel cost.  My bus was just 7 minutes away and I was still full at dinner time.  A great day.

Our train is due soon at Roma Street platform 6.

On Sunday we had the Club Buy and Sell and I walked away with over $120 in sales.  I may have purchased some items and also paid $20 for my usual table location.  The weather held off, but buyers seemed to be down a bit.  But there were plenty of bargains available.

Other activity next week, is the track from Rocklea Sidings to Sunnybank will get supports underneath it.  I might even have trains running before next Sunday.

Focus Now Switches to my QR 2000 Class Railmotors

So this week was supposed to be a slow week to recover from the last 4 days in Sydney at the Great Train Show at Rosehill.  Monday started with me getting out my WNI-32 module from WifiTrax and installing that in an NCE Procab.  So when assembled, the Procab becomes a wifi enabled device and it will work on any wifi connection.  The process to enrol onto a wifi network can be a bit laborious if there is a password set, unless the owner allows the WPS button to be pressed and it will happily join.

Tuesday's job was to get out my Far North Hobbies 2000 class railmotor set that was obtained down in Sydney at the second hand stall.  I made two baseplates to affix the wheels to.  They seem to run quite well.  I took one model over to Bob’s place on Tuesday night for our fortnightly get together, as he has a set of these railcars running on his layout.  We placed my railmotor next to his 2000 class set and my car was sitting about 1mm too high compared to his.  I thought it still needed to be lowered by at least another 1-2mm.  So on Wednesday I remade the chassis base plate and I think they were lowered by a couple of millimeters.  The railmotor was sent to the DC test track and the railmotor was just skidding on top of the rails.  So it needed a bit of weight added above the bogie.

On Thursday I added a slice of lead above the motor bogie and it ran smoothly with no more slipping.  The next task was to fit a decoder and wire up the second bogie to the decoder, bring the motor bogie pickup wires to the decoder and then run wires to the motor.  I then took it back to the DC test track and it ran very smoothly.  So the switch was set and it was put on the DCC test track.  It was given a long DCC address of 2004 as it is a passenger car version of the railmotor and I was very happy with its running on the layout.

However, upon checking this model against the QR plan, the model is too long, too high, too wide and just looks obese.  I was hoping that this two-car set was going to absolve my need from buying two 2-car sets of 2000 class railmotors from Guy at the Club, when he finally releases his models.  I have been patiently waiting for about 12 months, but I think progress is being made on his models.  I think I will need to still buy two 2-car sets off of Guy just so that my scratch built intermediate 2050 class car will be the same size as the end cars.  Guy’s cars are perfectly re-created in scale, unlike the Far North Models sets that are at least 5% too big in all dimensions. 

Late on Thursday I started cleaning off the flash from the bogie sideframes from the Far North Models kit.  I also started measuring the base frame for the second railmotor (the one with the luggage compartment). 

On Friday I cut up the base frame and spliced in the bogie support frames.  I then added a stiffening beam to the base frame.  I also got out the lead weight again and added that to the chassis frame, followed by the installation of holes for the wires to come up from the bogies up to the decoder.  I took the second railmotor to the shed and gave it a test run.  I was again pretty pleased with how it ran on DC. 

Saturday morning’s job was to install the decoder in the second railmotor and wire the bogies into the decoder.  Once that was done, I then tested the baggage car version of the QR 2000 class railmotor on the test track on DC again, and then switched to DCC mode.  I gave it an address of 2005 and gave it a run on the test track on DCC.  Very Happy indeed! 

Saturday evening I joined the British NMRA Region’s Brew and Natter online gathering.  There were 4 Queenslanders online there along with about 20 from the UK and Europe.  That was an enjoyable 2 hours of photos showing of layouts tours and discussion.

On Sunday morning I then put the two railmotors back to back, consisted them, and ran them around Acacia Ridge Yard, before I realised that I had equipment in the way towards Clapham Yard.  I still had not supported the trackage from Sunnybank to Rocklea Siding.  I'll get back to that next week.  So I relocated the railmotors to South Brisbane in a siding, then I realised that the sidings were not powered.  So I wired up the two sidings at South Brisbane with some wire jumpers.  But I did run the railmotors from the platform at South Brisbane to Park Road, until I found another dead piece of track.  I think I need to fix up a rail joiner.  Another job for this week.  So I ran the train back to South Brisbane Station where the set now rests.  I then replaced the KD on one railmotor as the jaws are not working.  I also need sound now to be added to the railmotors, but no one had a sound file and I can’t afford sound decoders for these railcars!

The Baggage Car version of the railmotor sitting in one of the sidings at South Brisbane.  Its twin is inside the house ready to get the start of headlights and marker lights.

I also need to install the lights inside the railmotor shells with connections back to the decoders.  I have pulled out 2 white LEDs for the headlights in one railcar, and 2 red LEDs for the front marker lights.  That is next weeks job.  I will also call in to Geoff and check out the paint options for these railmotors early this week as well.  I will hopefully have them painted before next Saturday which is Club meeting day.
