  1. The upper section of the Glen Afton Branch was severed from the main line system and the Rotowaro Township removed with the development of open cast coal mining in the Rotowaro area during the 1970s. Rotowaro late 2005 at a time when locos in matching colour schemes were extremely rare. Toll an Australian logistics company had recently acquired the operating assets of the railway from the former owners Tranzrail, the Government later bought out Tolls rail operating assets as the Government and Toll Rail were unable to reach agreement for the funding for marginal and loss making rail operations and investment. The Rotowaro terminal despatches up to two trainloads daily to a steel mill near Auckland and receives imported coal as required for use in a nearby power station. The Bush Tramway operates using a mixture of small ex-mail line and industrial locos. 185 is basically the NZR equivalent of the CIE J15 the standard motive power for mixed traffic duties until replaced by larger locomotives, several survived in industrial use until the mid 1960s. Mixed traffic 4-6-2 and 4-8-0 locos were the standard steam power in the branch in later years, with General Motors standard G8 export A1A A1A (NZR DB) taking over passenger and freight duties during the branches final years. Drewry 0-4-0 diesel mechanical tailing the const. The loco is basically a smaller version of the British Railways 04 class diesel shunter. Pukemiro Junction the operating base of the line and in 2005 home of an interesting collection of un-restored locos and stock. Pukemiro was the junction with a private railway serving a local coal mine and the only feasible site for an operating and engineering base for a railway. The loco is on the main line reversing back onto the train after coaling, the line on the left is the connecting line to the former mine branch. Climax B 1650 from a former logging line. The Climax and Heisler were popular logging Locomotives (Bush Lokies) a local manufacturer AJ Price developing close copies of Climax & Heisler locos and later industrial diesels. The Climax is currently under repair as a replacement for 185 which requires major boiler work. And now for something completely different a Bush Jigger or rail truck converted for carrying men and equipment on logging lines. This and a similar Jigger No 1 have been restored to working order since I took the photo in 2005. Recent restored Pukemiro Coal Company Peckett 1630 coaling at the Junction in 2014, this loco spent its working life shuttling wagons between the Junction and its namesake mine before taking up passenger duties on the Glen Afton Line.
  2. Its the first time I have been out and about since before the March lockdown, combination of the blues and miserable weather since travel restrictions were lifted. I originally planned to go on a bush walk but decided to check out the top end of the Glen Afton Branch line instead and see if the Bush Tramway Club had made any progress. http://www.bushtramwayclub.com/ The line was built to open up the coal fields west of Huntly and the section of line west of Rotowaro (lake of coal or burning embers) was closed in the early 1970s. The modern Rotawaro terminal both receives and dispatches train load coal but that's another story. The line west of Rotowaro was handed over to the Bush Tramway Club who operated a 5km section of the line as a Hertiage Railway from a base at Pukemiro Junction, while gradually restoring the line towards Glen Afton https://www.flickr.com/photos/46769458@N08/4649947978/in/album-72157623783391937/ Glen Afton station shortly after closure. Station site from a similar view point today. Despite the rural appearance the station served the Glen Afton Coal Company Mine complete with its own locomotive. The railway line is in the cutting behind the post box. The end of the line! Drainage system restored, sleepers replaced track ballasted rails most likely left in place since closure. Trains operate top and tail usually with a steamer at the up hill end and a diesel a the rear, the railway is planning to build a station so Glen Afton can once again become a destination. Looking down the hill line re-sleepered with rectangular hardwood sleepers, fangbolts and baseplates at joints, otherwise fangbolts direct to sleepers, Bit further down the line rails spiked to half round sleepers with every 3rd sleeper rectanglar with fangbolt fixing and baseplates. This was fairly typical of Irish Branch and Secondary lines including the SLNCR, though half round sleepers were gradually phased out as they became due for replacement. Halfround sleepers in closeup. Probably used for economy the Bush Tramway has approx once monthly outside of the summer/autumn months when the risk of fire is high. An other bit further down the line. The line climbs continuously from Rotowaro to Glen Afton steam sound effects are good. An earlier encounter with the Bush Tramway locos are fitted with smoke deflectors for a reason . Some interesting equipment including the local A J Price version of a Climax B Diesel rail trucks

  4. It you can come to an agreement with a designer an Irish or UK based printing service with SLA capability is likely to be a better option than Shapeways. https://www.google.com/search?q=3d+sla+printing+services+UK+and+ireland&rlz=1C1CHBF_enNZ752NZ752&oq=3d+sla+printing+services+UK+and+ireland&aqs=chrome..69i57j0.18285j0j9&sourceid=chrome&ie=UTF-8 SLA printing will produce similar results to plastic injection moulding and can be used to produce a pattern for vacuum casting (min vol 40 units) or small volume production. If you are unable to come to an agreement with CMAC, most locally owned 3D printing businesses should be able to recommend a 3D designer who understands the limitations of the technology and material and has experience in designing models and miniatures.

    GSWR 52 Class

    Some photos of the assembled test build of the 52 Class, I am currently finalising a number of amendments to the design before I release the production version at some stage in late 2020 early 2021. The kit will be supplied with brass and whitemetal castings, but will exclude wheels gears and motor and couplings. There is more detail on the assembly of the loco in my Tales from the Carriage Shops thread in the Workbench section of this newsgroup.
  6. A collection of GSR broad and narrow gauge loco drawings including GSWR Classes was published with New Irish Lines in recent years. The publisher of New Irish Lines Alan O'Rourke should be able to help if you want copies of particular diagrams. Updates on progress with the JM Design 52 Class/D17 kit including photos of a test build are available in the Manufacturers section of this website.
  7. GM produced a 3' gauge version of its GA8 Export Model for use in Mexico https://en.wikipedia.org/wiki/EMD_GA8#/media/File:NdeM_5406_(27443008661).jpg the GA8 model is visually similar to the B121 Class but is simpler mechanically and electrically, running on freight wagon trucks, with two traction motors mounted in the body with chain drive to the axles. Something more powerful than the Walker locos may have been required to haul trains over Barnesmore Gap and the Strabane-Letterykenny Line had freight traffic held up during the 1960s. Another possibility would have been to produce a B-B version of the GM6. Clyde Engineering produced similar locos for Victoria and Western Australia Government Railways during the 1960s by combining the 6-567C engine and main generator used in the GM6 with a Bo Bo chassis and running gear. https://en.wikipedia.org/wiki/WAGR_J_class_(diesel) https://en.wikipedia.org/wiki/Victorian_Railways_Y_class_(diesel)
  8. Point and crossing work assembled usually assembled using standard switch and crossing components with the rails between the switch and crossing tailored to form a particular formation, in practice 1:6, 1:8 & 1:10 crossing should be adequate for most applications. The EM Gauge Society members received a detailed manual https://www.emgs.org/wp-content/uploads/MANUAL_1_2_3_1_pages_all.pdf on prototype and model track construction including information on the different systems and assembly techniques including switch and crossing filing and assembly jigs. TOM Trackwork Standards can be easily extrapolated from the EMGS Standard and EMGS track, point and crossing jigs can be blown up to 21mm gauge on a printer or photocopier if you are not too worried about a marginally wider sleeper spacing. As Rick L suggested the best option is probably to build a small test track or a shunting plank with a couple of points and possibly a crossing as a test bed before committing to building a layout. Going back to prototype trackwork, yard and siding trackage on the CIE/IE system was generally laid in relatively light flatbottom rail on base plates or spiked directly to the sleepers, with bullhead restricted mainly to running lines and passing loops. The photo of the south end of Limerick Junction is a good example, the headshunt from the Waterford Bay with passenger train is laid in bullhead material, while the sidings between headshunt and the Cork Main Line appear to be laid in light flatbottom rail. Peco Code 60 Rail https://peco-uk.com/products/code-60-flat-bottom-rail for sidings, Code 75 or Code 82 for running lines if you want to re-create the contrast between 80, 85, 90 and 95 lb British Standard rails used up to the introduction of metric Standard BS/EN and UIC standard rails by CIE from the 1970s onwards. I got to learn perhaps too much about trackwork volunteering on a UK heritage railway including assembling full size 60cm gauge pointwork. Loco and stock on Peco Code 60 rail soldered to copper clad sleepers, Code 82 rail on lines in foreground. The layout was not a success I made the mistake of not allowing enough space in the 6' between parallel lines as they entered the curve and problems getting the double slip points to function correctly.
  9. Edenderry Power Station (R401 Edenderry-Rathangan Rd, West Offaly Powerstation (Shannon Bridge)R357 Shannonbridge-Tullamore Rd & Lanesborough Power station should be good places to observe BNM Energy Divisions rail operations. I griced BNM operations in Kildare and Offaly in the 90s and the newly opened Edenderry Station about 15 years ago. West Offaly Rail operations were readily visible from both the R357 & R436 including a loco stabling depot near Ferbane and Blackwater Works. There are/were a number of smaller isolated systems mainly in Kildare, Offaly and Westmeath these tend to be smaller in scale and have more in common with the Peat Railways in the UK, than the systems serving the peat fired power stations. BNM Energy Division rail operations are/were a basically scaled down 3' gauge 365-24/7 "Merry-Go-Round" train operation with fixed formation trains of (15) tippler wagons transporting milled peat rather than coal from stock piles to the power station. The "Clonmacnoise and West Offaly" tourist railway and museum of the early 1990s originated as a Fás scheme for redundant BNM Blackwater staff and appears to have developed into a successful tourist operation catering mainly for coach tours. Blackwater tourist train operations appear to have been discontinued because the tourist train operation was disrupting the flow of peat to the new West Offaly Power Station . The whole business of de-commissioning three recently built relatively low emission power stations rather than conversion to burn home grown bio-mass reminds me of the Greencore saga with the closure of the Irish sugar industry and seems to have very little to do with reducing Irelands overall greenhouse emissions while leaving the coal burning Moneypoint power station on line. Operation at Edenderry Power Station was/is interesting as trains from the West had to reverse direction in order to enter the power station. Train 1 passing under R401 underbridge arriving from Mount Lucas direction. This section of line is double tracked. Train 2 has coupled on to Train1. Loco Train 1 has uncoupled and is running forward on second running line. Loco of Train 2 pulls Train 1 & 2 clear of crossover as former loco of Train 1 prepares to couple on to Train 2. Track is typical BNM 'Main Line" with evidence of heavy sanding to keep trains moving. De-railed or defective stock was simply pushed to one side to minimise disruption to operations. Train 2 approaching Edenderry Power Station. Train 1 crossing over from "Main Line" to power station reception roads. Trains 1 & 2 approaching tippler building as an empty train departs on the balloon loop.
  10. Your layout concept is ambitious and you seem to have the space to fulfill your ambition. Building such a layout in 21mm gauge with handlaid track would be a lot more time consuming, perhaps taking 2-3 time longer than in OO using flexible track and ready to lay points, but the choice between OO & 21mm really boils how to how you prefer to spend your modelling time building models or operating a model railway/running trains. The difference in gauge is less noticeable and the view more realistic if the baseboards/track level is closer to eye level. Bullhead track was the standard form of permanent way on the Dublin Cork and Waterford-Limerick main lines from the 1900 or earlier, heavy (95lb) flatbottom rail was increasingly used for main line renewals from the 1950s onwards, CWR on concrete sleepers was trailed on the Dublin-Cork line during the mid 1970s, before becoming the standard permanent way for main line renewals. The Dublin-Cork main line was re-laid with CWR during the 1970s & 80s as CTC signalling was gradually extended southwards, Limerick Junction-Limerick may have been re-laid with CWR during the 1980s. The Limerick Junction-Waterford Line was likely to be laid with a mixture of CWR, jointed bull head and jointed flatbottom track. Jointed bullhead or and flatbottom track was likely to have been retained at Limerick and the Junction until the stations were re-signalled/layouts rationalised during the last 20 years. Photographs of a particular station or stretch of line is probably the best option if you want to model Irish track in detail due to the mixture of track material in use and condition even at a single station
  11. The brake van is designed to run on OO or 21mm gauge track. We are looking at a number of options for manufacture including 3D printing and vacuum castings locally (NZ) or the Far East, at this stage we are unable to confirm whether the model will be produced as an un-decorated kit or a decorated model.
  12. Preview of the latest version of the CAD work for the brake van. Its planned to supply the van with NorthYard NMRA RP25 Code 110 plated brass wheels with acetal centres on blackened brass axles set to OO gauge and Bachmann tension lock couplers with NEM pocket. The next stage is to produce a SLA printed pre-production prototype to check fit and durability of parts before progressing to the production version.
  13. Going off topic I enjoyed the video especially the ploughing in the background at Gormanstown and 171 to Galway and return. Some odd stuff taking place on the Midland, the signalman routing the empty Esso and Up passenger through the loop rather than the main running road at Killucan and the signal man at Athenry bringing an Up passenger to a halt on the Oranmore side of the level crossing, at the time infrastructure on both Galway & Sligo lines was in a poor state due to years of deferred maintenance, requiring interesting "work arounds" by staff on the ground to keep things moving.
  14. Many of the earlier American Road Switchers were set up to run long-hood or bonnet forward as it gave better collision protection to train crews, Norfolk & Western, Southern Railway later Norfolk Southern were the last of the major American railroads to hold on to this tradition. There is a story that when originally introduced some drivers turned the B121 locos to run bonnet first. Grills/louvers were fitted to the cab doors of the B121 Class and a requirement to run cab first was introduced following an incident involving a p.w. workers at Straffan in the early 1960s. T The p.w. gang had placed detonators and a flagman to protect a possession while replacing a rail, apparently the loco crew may not have noticed the flagman because of poor sighting or have heard the detonators (sound insulated cab) to stop before entering the possession. The grills/louvers disappeared from the cab doors at some stage during the IE eras.

    Greenway mania!

    Several of the proposed schemes in Ireland could come with a hefty price tag to compensate existing landowners as lines like the SLNCR & West Clare were abandoned and the trackbed mainly sold to adjoining farmers. There are a number of examples of heritage railways co-existing with cycleways and bridlepaths including the Waterford & Suir Valley, Carenarfon-Dinas section of the Welsh Highland and Northampton & Lamport in the East Midlands. Interestingly about 10 years ago the New Zealand Government considered converting sections of the national rail network as part of the National Cycleway Project to stimulate the economy in the wake of the 2008 Great Financial Crisis. https://en.wikipedia.org/wiki/New_Zealand_Cycle_Trail. In the end someone pointed out that rail was essential to export industry and no operational lines were converted to cycleways though a number of mothballed lines were converted to rail carting operations. The National Cycle Way and various rail carting operations has been good in supporting local economies in remote areas where rural -depopulation has become a serious problem with the decline in traditional small scale framing and rural support industries Rail cycling (Velo Rail) http://veloraildefrance.com/ and Rail Carting https://www.forgottenworldadventures.co.nz/routes-and-trails/category/2/rail-cart, would seem to be good alternative uses to Cycleways for "mothballed" lines, but liability issues with level crossings and a new and novel form of rail operation would probably be un-surmountable problems in Ireland
