The "Culcreuch Branch" as described below ceased to exist late in 2001.  Problems with track work, mainly due to temperature extremes over the previous 15 years, demanded attention and it was decided that a new layout would be constructed under our main dwelling in an area previously used as a double garage.  This area was insulated. lined and painted.

Construction commenced on what would be a continuous mainline running around the 7 metre x 5 metre room with a branch line, having small stations to generate traffic.

Here begineth the resurrection of the "Culcreuch Branch"
 
 

The layout uses the basic "L" girder construction using laminated 9 mm MDF (Two pieces 85 mm wide glued and screwed to provide the vertical of the "L")  This has allowed the layout edge to be curved to eliminate square corners.
Track has been laid on one of the Branch Line Yards and scratch built building and vehicles are temporarily in place
One of the yards on the main line. The main line, which loops around the layout room is fully wired for DCC operation.  A Digitrax Chief, currently with two DT100 throttles provides control. There are 24 points where the throttles may be plugged in
A scratchbuilt "Art Deco" RSA fills one corner of the, yet to be named town, on the Branch Line.
The cattle truck is a scratchbuilt OB Bedford, which gained a Third Place in the model Competitions at the 1976 Wellington Model Railway Convention.

This is progress to date 20 June 2005.

PREVIOUSLY

Unlike a large majority of the model railway fraternity I did not start out with Hornby Dublo or Marklin. My early years were spent building numerous models and structures with Meccano. During the 60’s I became involved with slot car racing and was a foundation member of the Heretaunga Slot Car Racing Club Inc in Hastings. Building and racing car models was most enjoyable and culminated in building a 1.32 scale car that set the original NZ record for a 100 mile race (actual distance). With the decline in the late 60s of this hobby in Hawkes Bay, I looked for something which would present a challenge and give access to a variety of skills.
My first purchase was a Triang tank loco and freight train complete with an oval of track. Many Superquick kits were purchased and assembled and a start made on a layout. Having no reference material was a handicap and working on one's own did not help. Frustration was the name of the game and had it not been for the opportunity of joining the Hastings Model
Railway Club, I may have given the hobby away. The first meeting of the Hastings Model Railway Club that I attended was at the home of Russell Smith. This was the first time I had seen models of the NZR prototype and I was hooked. With encouragement from Russell, John Dunne, Ian McPhee and other NZR modellers in the club I set about obtaining Stoker rolling stock kits and demolishing my fledgling British Rail empire and building an NZR layout. Motive power was required and my first attempt at kit-bashing a locomotive was under way. A Fleischman 'Black Anna' was purchased and the body modified, using plasticard, to build a representation of a Dubs A 0-4-OT. Chimney and domes were turned on a newly acquired
Unimat lathe and attached with the wonder adhesive, Loctite 1S12 This locomotive ran for some ten years before the plasticard became brittle and various parts started dropping off. A rebuild in brass was started and, like Sir Len Southward's first Model T, has not yet been completed.
I was Chairman of the Convention 74 Committee in Hastings, President of the Hastings Model Railway Club, Secretary of the Guild in the late 70s, in 1981 foundation member of the Wairarapa Railway Modellers and currently Secretary, Secretary of the Wonderful Wairarapa 92 Convention, Secretary of the New Zealand Association of Model Railway Clubs from 1993 to 1998 and President of the New Zealand Model Railway Guild Inc from 1996 to 1998.
 
 

 THE CULCREUCH BRANCH

A 1:64 scale slice of New Zealand

This layout is housed in a 9m x 6m converted garage. The aim has been to depict portions of the NZR and yards have been
based on actual stations or prototype practice. No particular area of the country is meant to be represented; rather I have chosen stations or yards that have been of particular interest to me, either by their style, positioning, or some peculiarity. Sean is based on Matiere on the Stratford-Okahukura Line. Kahutara is based on a foreshortened Featherston. Kahutara is the terminus of the railway proper, with the Katrina Bay being the Port and industrial sidings accessed from Kahutara.. The layout may be operated as a continuous loop for just running trains; very handy for trialling or running in locomotives, etc. During operating sessions the layout is run in
a point to point configuration.

Let us board our Model T Railcar, RM 5, at Kahutara for a trip over the Culcreuch Branch of the NZR. Leaving Kahutara from the railcar dock, we pass into a tunnel under the town of Kahutara and emerge to pass over a bridge at the head of Katrina Bay and enter Sean.  Sean is a small station with a loop and goods shed siding with back shunt and low loading bank. Heading south out of Sean we descend the 1:50 grade and pass through the second of several tunnels to pause at Whareroto to cross a freight headed for Kahutara. With clearance obtained we pass under the road bridge and enter another tunnel and emerge to pass under a combined road rail bridge on the Culcreuch - Sherenden Branch before entering Ngaumutawa. Here we cross another goods train heading for Kahutara. Leaving Ngaumutawa we again pass under a bridge on the Culcreuch - Sherenden Branch before diving into another tunnel to emerge alongside Kau Creek which is followed for a short distance before being crossed on an 18 span wooden bridge. A short climb brings us past the abandoned turntable and loco facilities before being switched into the railcar dock at Culcreuch, the southern terminus of the branch. Culcreuch is an industrial centre with a manufacturing plant serviced with its own private siding. A round roofed goods shed, a high loading bank, stockyards, coal and log traffic make this a busy station.
We are in time to catch a cab ride in the F class 0-6-0ST to the coal bin at Fernridge on the Culcreuch - Sherenden Branch. Our train consists of the F and four empty L wagons. Heading north out of Culcreuch we are immediately into a 1:47 climb through a tunnel to cross the three span bridge across the upper reaches of Kau Creek. Passing the Fernridge junction we
proceed to Sherenden to run around our train so that we may proceed up the Fernridge Branch.  Climbing still higher we again cross Kau Creek on a short single span bridge before heading through yet another tunnel. We slow to pull up under the coal chute at the R W G Fowler Coal Company's mine. After filling our four Ls with high grade coal we move off to drift downgrade to the junction and into Sherenden for the loco to again run around its train before proceeding down to Culcreuch.  After leaving the full wagons in the yard the loco is run down to the loco depot for servicing. A short walk from the loco facilities and we are just in time to get our seat in the standard railcar for the trip back to Kahutara.

When the layout is used for running-in rolling stock, the train travels through Sean, Whareroto, Ngaumutawa, Culcreuch, Sherenden and back into Sean. This gives continuous running.
 

Operation

The layout has been designed with operation in mind and a working timetable produced which contains the rules and regulations governing the Culcreuch Branch. The Culcreuch Branch uses a version of the tried-and-true car-card system of dispatching rolling stock. We have adopted many ideas from articles in both American and New Zealand publications, and fine tuned them to suit our own purposes. The current car card or waybill is a four cycle item, which has four separate traffic movements. Waybills are placed in a pocket on a separate card which is associated with one wagon on the layout. The card contains 
information specific to that wagon, while the waybill contains information on the traffic movements the wagon will perform. Information includes:  Destination of the wagon and the receiver of the goods.  Originating station and the original consignor of the goods.  The contents of the wagon, or if it is loaded at all. At the end of an operating session it is the responsibility of the traffic manager to cycle the waybills. i.e. change the waybills to show the next destination for each car. The layout is operated under a fast clock giving 24 hours of operation (midnight to midnight) in two hours actual time. In all 17 trains are run in the 24 hour period. These include commuter and freight services between Kahutara and Culcreuch and workings on the Culcreuch -Sherenden - Fernridge Branches. Ideally five personnel are required to operate the layout, although it can be done with a minimum of three.
Short yards and tight curves restrict the classes of locomotives that can be operated on some portions of the Culcreuch and Sherenden Branches. This has been intentional as I prefer to operate short trains. Why have I chosen these particular names for the branch and stations?  When we first shifted to the Wairarapa we lived at Kahutara, 44km south of Masterton. Sean is named after my son who has grown up with my railway modelling and has been the main instigator and developer of the working timetable. While Sean was in the local Air Training Corps Squadron he became involved in gliding and we spent a lot of time flying off an airstrip at Whareroto in the south Wairarapa. Ngaumutawa is the name of the road where my factory is situated and Culcreuch is the name of the family castle in Scotland. Kau Creek is a polite corruption of the corruption Karl Morris made of Culcreuch. Fernridge is the area of the Wairarapa in which we live and Sherenden is where my wife Ann spent her childhood.
 

Construction

The framing of the layout is the tried and true L girder construction. In the early stages 3 in x 1 in pine was used for the L girder but later construction was carried with 18 mm x 75 mm custom wood planks. This material together with the correct screws makes for a very sturdy and reasonably inexpensive structure  (considerably cheaper than pine). The track work and turnouts at Sean are hand laid using rivets fitted to ply sleepers with the rails soldered in place. The rest of the layout is laid with PECO track and turnouts. The track base is custom wood cut to suit with an overlay of Pinex. The track base was run right round the layout with additional risers each side of bridge sites and a bearer below. The track was laid and, when satisfied with the alignment, the baseboard was removed for each bridge site and, where required, holes were drilled in the hearer for the bridge piles. The piles were pushed through the bearer and the bridge span/s offered up under the track. The piles were then pushed up from below to suit the particular span and glued in place. All bridges have been built from NZ Model Railway Guild Plan books. Fifty one piles were driven for the 18 span curved wooden bridge crossing the lower reaches of Kau Creek. The spans are all 10 ft, 11 ft or 12 ft wooden spans. These were positioned on the piles and with the aid of a length of in x in the piles were all driven to their final depth and fastened in place. The sleepers on this section are a mixture of PC board and
wood. The rail is soldered to the PCB sleepers. The rugged hill country was built up using narrow strips of card woven, basket fashion, to the contours required. This matrix was then covered with strips of old sheeting dipped in thin plaster. From this base rock faces were formed using aluminium cooking foil as a mould. After removal of the mould, some additional carving created the effect required. Shadow and additional texture was given to the rock faces with watered down India ink and various powder colours. Open country was created using the zip texturing technique. Scrub has been created with a mixture of under felt and raw wool. The scrub was coloured by a light over spray of black followed by sprinkling on a mixture of dyed sawdust and ground foam. In the swamp area of Kau Creek binder twine has been used to depict swamp grasses. Trees are a mixture of yarrow, hydrangea and some Woodland Scenics.
 

Locomotives, Rolling Stock & Structures

The locomotives are a mixture of kit and scratchbuilt models covering both steam and diesel. Rolling stock is mostly Kit built with some scratchbuilt. Apart from the Model T railcar, Standard railcar and an 88 seater under construction, passenger rolling stock is limited. Bridges, goods sheds and station buildings are all scratchbuilt. The town behind Kahutara station will be a mix of scratchbuilt and modified DPM kits. Control is by Digitrax DCC (Digital Command Control) using the Digitrax Chief. Locomotives are fitted with a variety of Digitrax decoders.  Turnout control is by two position rotary switches operating the throw bar by torsion rods. The rotary switches provide the mechanical operation of the turnouts as well as switching the
frogs. Where it is not possible to use this system, Fulgurex slow motion point motors are used. A lot of work is still to be carried out to complete the scenery, buildings, ballasting and detailing which is all part of the fun of model railroading.

Over Queen's Birthday 2001, weekend Ian visited the Auckland 9 mm modellers at the Exhibition they staged in Henderson in conjunction with the Auckland 3/16 NZR Modellers.  The Auckland 9 mm group wanted to set up their large layout and insert the new Te Kuiti station modules ready for wiring and testing.  The new section is 7.2metres long.
in the foreground terry Bradley is building a diamond crossing while Phil Rzoska and Ian, (background) solder the wiring to PCB rail connections.
Phil Rzoska's DSA was used for checking the continuity of the wiring.  A meter was available, but the DSA was more interesting.  In the foreground is the chassis for a 9 mm Df 2 - Co + Co - 2 diesel-electric locomotive.  During the course of the weekend the new Te Kuiti modules were joined to the layout in place of the old Black Creek sections and  a temporary connection was made to the existing control; panel to allow the layout to operate for the public on the Monday
