My very first Ops Session...

Things have been a little quiet on the layout front at the moment as we are doing renovations to our home which are taking up most of my spare time, so its basically ground to halt.

However I did get the opportunity last weekend to participate in my very first Ops Session outside of our own layout.  My good friend Brendan Dennis held another shake down session on his D&H - N Scale layout - http://dh2ndsub.blogspot.com.au

I had the opportunity to operate on the Whitehall Yard with another operator John, we were tasked with the North & South switching of the yard operations.  I must say being a yard master is great fun and really gets you thinking, Brendan's Whitehall Yard is around 3m (10') long incorporating an engine facility, yard leads, run arounds, caboose tracks, seven (7) tracks and a passenger siding to the south.

I really enjoyed operating the yard with John, and the session went really well, Brendan's layout is seriously impressive and the amount of work and the stage he is at presently is amazing for the short time that he has been working on it.

As I won't have a full size ladder yard on the JL&T I look forward to spending some time switching Whitehall in the future.  

Big thanks to Brendan for the invite, and for a great insight into Ops Sessions!

Another SE8C almost complete...

Well today I started the process of making another five (5) SE8C boards.  The process is relatively easy now that I have made three of them.

Another four to go and then it will be onto wiring all the push buttons for the fascia's.

YouTube Live Streaming - Wiring - Digitrax SE8C Board...

Just for fun and to see how it works, I'll be live streaming the wiring of a Digitrax SE8C board.

Starting in about 20 minutes.

Final stretch of Tortoise Installs...

We are now finally into the last stretch of the Tortoise Motor installs, the northern area of the layout is the last section to receive them, and also one of the most dense concentrations of them too.

The majority of the motors are for passing sidings & crossovers.  I have installed three along the back edge of the backdrop for the small spurs for a couple of industries as it will save operators from having to lean over the bench work.

As can be seen it is fairly busy underneath this section and will get even busier when all the wiring for the push button fascia controls are added too.

Once this action is complete it will be onto installing the remaining SE8C's and wiring in the push buttons and Tortoise's.

Jas...

Next round of Tortoise Installs - Passing Sidings...

So last night I began installing the all the Tortoise Motors for all of the passing sidings.

And at the end of the early hours of this morning, I had most of them installed.  A few tweaks required on the Walthers Shinohara turnouts to get them operating properly.

Another 24 to go...

Jas.

Mainline Tortoise Motors installed...

Well last night I finished the installation of the Tortoise Motors on the mainline for the layout.

There are 30 in total for the entire mainline.

There are another 24 to install for all of the passing sidings that will also be controlled by JMRI & Fascia Panels.

I've also installed a couple on small spurs that sit at the back of the layout, this will stop operators from having to reach over the layout to operate the turnouts.

Next step is to install the remaining switch motors, then onto wiring them all in and back to the SE8C's, and then the fascia push buttons.

Some of the push buttons will be duplicated so that they can be operated from either side when the track travels through a backdrop.

Ready for the detection & signal installation...

Well yesterday I removed all of our locomotives and rolling stock from the layout and cleaned up the deck.  Just waiting on a shipment of another 24 - Tortoise Motors, and another 3 - Digitrax SE8c's and we are ready to make the major push to install all the signal wiring, remaining Tortoise's, LocoNet, power bus for the accessories, and the boards with hardware.  

After placing all the isolators for the detection blocks I found we had created a few dead sections that had no feeders.  These will be added when we do the rewire as the have to wired to the BDL's, so I have another two of them to wire up on boards, and another 5 SE8c's boards to wire up too.

In the order from Litchfield Station I also got some ready made R15k resistive 33" wheels sets too, this will allow me to quickly make up a few pieces of rolling stock and a caboose to be able to test out the detection sections, BDL's and ensure JMRI is working and receiving the data from the LocoNet.

Seeing it's our summer over here I'm hoping to throw a wiring session or two, followed by a BBQ lunch, and then a little ops session after with a great group of guys that live within an hour of us.

Finished Blocking the layout for Detection...

Well last night I finished the arduous task of adding insulators to the blocks for the detection rail on the layout.

I also took the time to remove a few turnouts (ElectroFrog to InsulFrog on the main) and remove a #8 turnout that was no longer required.  I also drilled a few holes for Tortoise rods that needed to be installed on some of the sidings.

Next step will be to test the track work as by adding the insulators I have created a few dead spots on the layout.  After that it will be onto adding the remaining Tortoise Switch Machines.

Jas...

It's all clear ahead...

Well tonight I have been playing around with the colour mix of our double head - searchlight masts.  I have installed this one on the layout to test the colours under actual layout lighting.

The first photo is with the LED's being driven at 12V, the two below are being driven at 5V which is the eventually output from the Digitrax SE8c Boards.

So far I'm pretty happy with the primary red & green on the Tomar Searchlights, the yellow which is driven by both the red & green is acceptable too.

I'm finding that I need a brighter green & dimmer red to get the yellow to pop above red, and also not look orange.  Its a slight trade off as I'd like to have the green dimmer but this would turn the yellow more towards the orange spectrum.

Even the camera which is Nikon J1 is picking up the colour difference on the mast, and this is under the layout lighting which is a NEC 6000K 38W Daylight Fluorescent Tube.

Next step will be to try out the double head dwarf and see how they look.

Cheers,

Jas...

Ready for some Re-Wiring...

Well Santa came a little early today.

In time for a few nights of re-wiring the entire layout for the detection & signalling.

The layout power bus will be re-run from the PSX Circuit Breakers and the common rail detection to the BDL168's that need to be installed around the layout.

I also have to install the PSX-AR for the new Classification Yard too.

The next step will be to make up a power district board above the NCE DCC Command Station that will house all of the power district PSX Circuit Breakers, the Auto Reversing CB will be located nearer to the areas.

More soon.

Classification Yard progress...

Well over the last week in between working on the detection & signalling I managed to install the remainder of the drywall/plaster roadbed and cork sub roadbed for the Classification Yard.

I have also began laying the track at the entrance that forms the wye in the South Bend area.

Next step will be to finish off the track, and begin wiring.

Jas...

JL&T Detection & Signalling Plan...

Ok folks its taken a little time to get here, but we finally have the detection blocks and signal placement done.

A very special thanks needs to go out to Brendon Dennis who has guided & educated me through the finer points of detection and signal placement.

We both spent about 2 1/2 hours the other night physically marking out the detection blocks and signal mast/dwarf placement.

Here is the detection block & signal mast dwarf plan:

The naming conventions on the plan are area representative as I've only really named one location "South Bend Curve" (SB).

When looking at the plan the triangles are the isolators, these are placed on the inner most rail (nearest to the fascia) and are classed as common rail wiring.

As can be seen in the photo below the inner most rail is marked with a yellow dot, this will have an insulated rail joiner placed at this point and separate the two detection blocks.  You can see the naming convention as well.

The arrow with the dot, dot, M is our symbol convention for a double head signal mast, controlling to the left (east) of this detection block boundary.  The T7-3 represents Tortoise (switch machine) Number seven (7), on SE8C board number three (3).

Next stage is to add all the insulators and then the tedious task of re-wiring the layout for the common rail detection will begin.

Track Work on the Classification/Staging Yard begins...

Well this week was the beginning of the installation of the track work for the Classification/Staging Yard.

The yard will be operated as a functional stub-ended classification yard and will be one of the two main staging areas for the layout.  The second staging yard will be located beneath the top northern deck, and will be fed by the return blob near the paper mill.

The reason for starting the yard now is that it forms part of the new "wye" for the layout, it is also part of the blocks that will be detected & signalled first.  So I need to at least complete the entrances, it will also help with any future ops sessions that are held.

Diagram of the Classification Yard...

The first step to get the track from the centre peninsula yard lead entrance was to make a small span across the void that was the existing layout roller door opening.  This was made with 12mm - 5ply plywood, I also added 100mm side to either end in case of derailments in there that could see the long drop down to concrete below.

Next stage was to lay out the north & south yard leads to check alignment and the curve radii.

Below is the North Yard Lead entrance...

Below is the South Yard Lead entrance...

After the yard leads were checked I placed the first series of turnouts into place and roughly placed the start of the storage tracks to check spacings and alignment.

The yard is split into north & south storage tracks (3 tracks each) with a common escape track that is fed by a series of crossovers towards the end of the yard.

Next step will be to finish of installing the remaining plaster sheet for the sub roadbed, and install the 3mm cork sheet and lay the remaining track.

Jas...

First Digitrax - BDL168...

Now that the first stage of the LocoNet has been installed I decided to install the first BDL.  These are pretty much the same as the SE8C in regards to setting up the backing board.

The backing boards are being setup on the same size a the SE8C boards.  The only real difference between the two installations is the wiring size.

The BDL connections require a larger diameter wire size as they will be carrying track power, I've opted for 1mm Solid Core wire for the connection between the 44 pin connector and the terminal blocks.  

The solid core wire also assists with forming the wire to fit nicely on the board terminal strip, one trick that I have picked up is to give the end if the solid core a tap with a hammer to slightly flatten the wire so that it passes through the terminal strips on the 44 pin connector.

The above red wires represent one (1) detection zone, which incorporates four (4) detection blocks, there are four (4) detection zones on the BDL which allows for a total of sixteen (16) detection blocks.  Once this board is complete it will be placed in the South Bend Curve area, and the blocks will be connected from there.

UPDATE:

And finished...

Relocation & Rewiring...

With the forward progress of the detection & signalling installation it was time to relocate the layout PC and the NCE DCC Command System.

I had my good friend Brendan over during the week to set up the LocoNet & LocoBuffer to the layout PC.  This meant that I had to relocate the PC to its new nook and rewire the layout to it and begin the installation of the LocoNet.

The new are housing all of this is directly behind the dispatchers nook, there is a small open ended box that houses the layout PC allowing for easy connection to it, cross ventilation and easy access.

I've also cleaned up all the wiring in the area and began the process of clipping everything up to keep it neat and tidy.  The power board above the PC is a surge protected board that supplies power to the lower board which has individual switches to turn off each piece of equipment.

The NCE DCC System sits on top of the PC Box along with the LocoBuffer box.

This little nook has room for a swivel chair on rollers so that I can work on the wiring with ease, once the layout fascia's are finished there will be drop curtains installed around the layout to hide all of the under bench areas & storage.

Altering track work to install Tortoise Motors...

The last couple of days has seen some more alterations made to the track work around the centre peninsula.

To install the Tortoise Motors I have had to shift a few turnouts, when I originally did the track work for the layout I had decided to just use Caboose Ground Throws.  Now with the installation of detection and signalling the mainline requires the Tortoise Motors to be installed.

One issue has been several area that had timber framework for the layout blocking.  I adjusted the track work and replaced several turnouts to get it all to work.

It has worked out quite well as I have removed the Walthers Shinohara turnouts from the area and they are all now PECO Code 83 - Insulfrog Turnouts.  The track work is now also flowing a lot better through this section and I have gained a little length in the sidings on the right (nearest to the fascia) and this will help with operations too.

More photos soon.

MOW crews alter track work for the Layout Expansion...

UPDATED:  10/11/14...

Well today I spent a couple of hours altering the track work around the south/east portion of the existing layout.  I've updated the photos below to reflect todays progress.

This section was originally the layout staging area, consisting of three tracks around 10' (3m) in length.  With the addition of the new layout area, and the staging/classification yard this section needs to join with it.

The existing staging area will become a mainline (working from fascia to backdrop), passing/storage siding and lastly the industrial spurs.  The industries will all be background buildings and will be predominately be scratch built with styrene.

The photo below shows the new classification yard lead running into the passing/storage siding, this allows trains to either enter/exit the yard onto either the passing siding heading westbound (towards the bottom edge of the photo) or through the #6 crossover onto the mainline (nearest the fascia).  The RH turnout to the right is the first of the industrial spurs for the area.

This section will be joined to staging/classification yard and form the layouts first "wye", it will also be adding more switching opportunities again with narrow bench work.

The photo below shows the possible installation of a #8 (Medium Speed) Crossover that I'm considering installing, this will give the dispatcher another method of allowing opposing trains the ability to change into or out of the passing siding onto the main.  It will also serve as a runaround/spot storage for locals & switchers to switch out the industries along this area.

And below is overview shot of "South Bend Curve" and the series of crossovers connecting the Northern & Centre peninsula areas of the layout to the South end.  The yard lead connects to the lower section of the classification yard and also forms the "wye" as mentioned above.

More soon.

More Signal Goodies...

Well this week I received some more Digitrax SE8C's & BDL168's, I have my LocoBuffer - USB for connecting the LocoNet to the PC & JMRI.  I also got another 12 Tortoise Switch Machines (bringing the total to 30) in this shipment.

I've decided to get 100m of CAT6 cable for all of the detection & signalling wiring, and this will be standard I will use throughout.  I have made up the second SE8C too, I've not got this one down to about 2 hours to make. 

I have another lot of Tomar double head - Searchlight signals here, and am waiting on another order of single & double head dwarf signals to arrive direct from Tomar.

Over the next few weeks I will begin by installing the power bus for the SE8C boards, work on installing the remaining Tortoise SM on the main, and begin connecting these to SE8C's as we go.

My first Published Article...

Well yesterday my very first published article has appeared in Model Railroad Hobbyist magazine, it was written some time ago but very happy that the team at MRH accepted it and now published it.

It has always been one of my goals to write an article when I started in the hobby, I'm a firm believer in sharing and helping out others who,are getting into the hobby.

First Operational Digitrax SE8C for signalling...

Yesterday I finished off installing the first Digitrax SE8C onto the layout.  It has been located on what will be known as South Bend Curve (a purely fictional place) that is located in the L&T Branch area and interchanges with the new staging yard.

I installed it here because there are a series of turnouts that are behind structures, and also hard to get to.  They are also Walther's Shinohara turnouts that require either a manual throw (caboose ground throw) or electronic like a Tortoise Motor.

So far I have installed the backing board with SE8C and screw terminals and connected three (3) Slow Motion Turnout Machines (SMTM).

The board is placed roughly in the middle of the cluster of turnouts, the SE8C has the ability to control eight (8) Tortoise type switch machines.

The most important thing that I can suggest to anyone considering or about to embark on the installation of signals, is to clearly mark EVERYTHING!!  I have the Digitrax SE8C wiring diagram for the 44 Pin Connector right next to backing board, which is also clearly marked with what wires go to the SMTM & Push Button Switches.

Once the SMTM & Push Buttons are connected I mark the backing board with a common naming convention related to the turnout.  This is as suggested by Digitrax and is also used in JMRI to name the individual turnouts too, I use LT#--, this being Local Turnout & the turnout number, followed by B#-- this representing the Board Number in the system.

When labelling the push button switches I also use the same LT number so that it is easy to identify which switch operates each turnout.  I also place the turnout number on the SMTM too.

I have also converted the fascia panels with the momentary (normally open) push button switches.  These are extremely easy to install both ion terms of wiring and into the fascia compared to the toggle DPDT switches.

So far the installation has gone extremely well, with no major issues either.  I have had to replace the +VE Common wire for the push button switch power as the connection was dodgy.  But apart from that all good, there is a huge amount of work in installing signals, but it is also very satisfying to see everything coming together and operating.

Next step is to install the remaining SMTM for this SE8C and then work on installing the LocoNet.
