  1. Established in 2011 the business is a New Zealand based manufacturer of ready to run models and kits of (mainly) 4mm Irish outline locomotives rolling stock and accessories. Migrating from Ireland in 2004 the current range reflects my modelling interest Irish Broad and Narrow gauge in 4mm scale and large scale American (1:20.3) narrow gauge. July 2021 is turning out to be a momentous month with the opening of our on-line shop https://jmdesignmodelrailways.com/, the release of a CIE 20T Brake Van the first of a range of 3D printed ready to run wagons just over 12 months since we first considered the project. Although we originally considered 3D printing for the first rolling stock kit the Bulleid 4w Heating and Luggage Van of the 1950s the model was manufactured as an etched brass kit with whitemetal fittings as we could not achieve an acceptable standard of finish using current 3D printing technology. The shift in focus from kits to rtr models using 3D printed technology was partially in response to improvements in 3D printing technology, increased demand for rtr models and relatively static for kits. The last 12 months has been a steep learning curve both in relation to identifying the capabilities and limitations of the technology and the 3D printing industry for model railway applications. We are purchasing our own 3D printing machines to establish in house printing capability while working with our current contract printer to improve the quality and consistency of prints.
  2. After 10 years our on-line store is finally up and running!!!!!!!!!!!!!! https://jmdesignmodelrailways.com/ . July is turning out to be a momentous month with the completion of the first batch of 20T Brake vans and the arrival of components allowing the release of the 52 Class locomotive kit, the etched parts are currently on order for the second batch of "Tin Vans" with an expected release in Aug/Sep 2021. Railtec Models are preparing graphics for the second batch of brake vans and the bulk grain wagon and we expect to complete decorated samples of these wagons by late August 2021. Hopefully I will get round to setting up a OO or 21mm module/layout for displaying the models! We will set up a thread in the Small Suppliers/Manufacturers forum to announce new models and provide progress updates.
  3. Bachmann used a variant to the Klien-Linder principal with its 1:20.3 scale DRGW K27 Class loco or "Mudhen" The driving wheels were fitted to hollow axles that were free to move sideways on an inner axle to allow the loco to run round curves. The outside cranks remained in a constant position to avoid problems with the coupling rods and outside valve gear and the driving axles were self centering to avoid problems with hunting. The only problem was ensuring all 8 driving wheels and the trailing truck axle are on the track when re-railing the loco after a de-railment usually splitting a set of points. Driving wheels normal position for running on straight track. 2,3,4 wheelsets offset with packers to illustrate sliding effect. The low slung DRGW Mudhens may look odd to British eyes but don't quite fit into the Worst Looking Loco category
  4. Great modelling very much in the spirit of ingenuity of the UTA engineers re-using parts from existing coaches to build the AECs and groundbreaking MED diesel trains. I am looking forward to seeing your MPD railcars.
  5. I commissioned York Modelmaking to produce a laser cut model of a GSWR hip roof signal cabin for use on my own layout. I was asked by a member of the group if he could order the kit direct from the manufacturers. I am accepting expressions of interest for a minimum of 10 signal box kits which are likely to be priced in the £45-50 price range. The kits are laser cut from MDF and Rowmark plastic parts and include York Modelmaking slates and ridge tile sheets. The kits will be supplied direct from the UK and may be subject to customs and local taxes upon entry to the EU or other countries. The model was completed with Wills Materials sheet slate roofing and ridge tiles as the slate and tile sheets were not included with the original set of parts. I mitered the corners of the MDF brickwork wall panels as it gives a more realistic effect than tab and slot joints sometimes used in laser cut stone or brick buildings. While I am fairly satisfied with the staircase, etched windows would look more effective and may be offered as an option. If there is sufficient interest in the signal box, I will certainly look at other buildings and structures including a typical WLWR Sligo Road & Thurles Branch station building, goods shed and platform shelter.
  6. Having completed the test build we are planning to release the kit in June-July 2021 at $290NZ excluding shipping, import charges and local taxes The majority of the kits have been pre-sold or reserved, but we will continue to accept expressions of interest on a 1st come served basis in the event of cancellations. No 93 arriving at Keadue on the daily passenger. Not sure what a broad gauge train is doing on the narrow gauge. No 93 is OO the coaches 21mm and the track 12mm, I desperately need to build OO & 21mm modules of layouts. 93 broadside the number plate is temporary fixed with double sided tape as the model is based on 59. Boiler fittings and tender are SSM, boiler/firebox step ring, buffers, tender toolboxes are JMD brass castings.
  7. My first "proper" trainset was a Triang-Hornby "South African Goods" which I selected as a Christmas present when I was twelve. Oddly enough the set was steam age British Railways with the recently introduced M7, two green open wagons, an "Ice Blue" fish van and a 20T goods brake, the set was battery powered as the budget did not stretch out to a mains controller. I think I was attracted to the set having seen the M7 advertised in Model Railway News and a reasonable number of wagons. The set did not last terribly long I traded the M7 for a Hornby diesel shunter about 12 months later, goodness knows what happened to the wagons and track, at the time I was very good at taking models apart to modify or rebuild into something else, but never quite completing the models.
  8. Received a decorated sample of the brake van, with graphics by SSM & an Auckland based pad printing business, one of the final steps in producing the van as a rtr model. We are planning to produce the van using 3D printing technology as injection moulded plastic and resin casting were not viable options. We expect to start marketing the van by on-line media and the model press during the first quarter of 2021 for potential release in mid-late 2021.
  9. A German 0-6-0 diesel shunter from Fleischmann or Roco is probably the best option for a free lance loco in terms of reliability and smooth running. I ordered a custom built Bull-Ant chassis from Hollywood Foundry for my E421 class, expensive but probably the best option apart from scratchbuilding a chassis.
  10. There is a piece on the CIE hopper containers in a late 1960s IRRS paper on CIEs containerisation programme. They were used for grain/malt traffic during the 1970s, there are several photos of cuts of wagons with hopper containers in Tralee North Kerry Yard. It likely that road transfer was used at each end of the journey. The paper indicates that CIE would have preferred to use a standard bulk container with end tipping discharge (by truck) but the hopper container was developed because of height restrictions in the customers premises.
  11. There was a similar issue with the non-availability of Markits driving wheels approx. 12 months ago. The change in the hobby from manufacturing a small range of generic Romford Wheels to the current larger prototypical range has probably contributed to the current problems with supply and availability. Interestingly I am experiencing similar problems with the supply of wheels from a non-UK manufacture, who have been unable to source nickel silver tyres from their usual manufacture during the past 3 months because of Covid 19 restrictions.
  12. I am currently looking at the viability at producing a ready to run OO gauge brass steam loco in conjunction with a Far Eastern OEM manufacturer of high quality brass locos and rolling stock for the American, European and British markets. I am considering the Midland "Cattle Engine" as a first batched produced model of an Irish steam locomotive as it fits in with my own personal interests and its a good example of a large modern (1920s) mixed traffic design in contrast to the smaller Midland and GSWR "standard" goods types. The model would be produced as a limited edition with each model individually certified and are likely to be a sound investment. I am open to considering some of the larger GNR express passenger classes if there is insufficient interest in a Cattle Engine https://www.surveymonkey.com/r/HD3TB6Z
  13. Several Luggage vans were sometimes marshalled together with a Post Office van and Heating and Luggage van in mail trains. In the mid-late 1970 rake of Parcel vans lost their gangways and were re-painted in an all-over "Tan" livery (similar to the newly introduced Van Hools buses) for use on Connolly-Dunlaoire parcel trains. I don't know the numbers the vans were lettered to "Run between Connolly & Dunlaoire-Pier" "max speed 35mph". SSM produced decals for the Silver, Green & Black & Tan liveries for the original batch of kits, though the "1.5t evenly distributed" section of the decal would need to be re-sized.
  14. 2128N is an ex-GNR(I) bulk cement wagon built for Boyne Road (Drogheda) to Tegral Athy bulk cement traffic. One of the ex GNR bulk cement wagons 2134N survived into preservation and may even survive at Dunsandle. The van was sent to Mullingar for scrapping but CIE staff were unable to scrap the wagon with ordinary cutting gear as cement had solidified inside the hopper. Guards would not travel within a 4w Luggage van unless there was nothing else available, CIE guards were really impressed when the BR vans arrived in the early 1970s complete with decent seating.
  15. The model is a prototype, we are are currently revising the design to address the issues identified during assembly including the appearance of the roof. Extending the roof at each end in addition to reducing the edge thickness should help.
