  1. One of the challenges of building an Irish Broad Gauge steam locomotive in OO gauge! On the majority of outside cylinder steam locos the conrods are on the outside of the coupling rods but not on some outside cylinder 4-4-0 classes including the GNR Compounds and Metropolitan 4-4-0T. It basically leaves the builder with the choice of cranking the coupling rods to avoid running problems or fitting the conrods on the outside of the connecting rods and using a longer crank pin bush.
  2. Nice to see the subtle weathering of the Tin Van it must be 5-6 years since they left the Carriage Shops in ex-works condition! The open un-cluttered nature of the place with no goods shed or station building reminds me of Fenit which I first visited in the summer of 78 several months after the last train (beet special)departed. Have lots of fun!
  3. One of my favourite might have been scenarios was a "joint" MGWR-GNR line from Kells to Cavan via Virginia and possibly onwards to Enniskillen a better routing for Dublin-Cavan & possibly Monaghan passenger services than by Inny Junction. An amalgamation between the Midland and the Great Northern was actually considered in the early 1920s with the LMS taking over the lines north and west of Dublin and the GWR taking over the GSWR, DSER and West Cork.
  4. Interesting both MGWR signs, the Inny Junction one is particularly interesting including Clones Junction a destination on the Great Northern. There were no advertised connections between the Midland & GNR at Cavan in the 1897 MGWR WTT, though there are advertised connections are advertised between Navan Junction and Kells but not Oldcastle in the same timetable. The MGWR had running powers over the GNR between Navan & Kells possible reason for the connection. In pre-amalgamation point Cavan was a major interchange point for cattle traffic from the Midlands to Belfast Port with trains working through between the two systems, presumably with loco change at Cavan or possibly Clones?
  5. There are simpler & quicker ways to handlay track than using slide on plastic or 3D printed chairs or solder the rails to every sleeper! Main Trunk tall steel viaduct scene with handlaid track on viaduct assembled using "Micro Engineers" parts. S Scale NZR 3'6" gauge track (OO) with copper clad sleeper every 5th sleeper spacing, missing sleepers will be fitted using stripwood sleepers. Some NZR 3'6" gauge layouts use Peco or Atlas for hidden trackage and handlaid track in scenic areas. Viaduct scene took 18 months to construct. Layout was exhibited this weekend at Whitianga Train Show first time I have been to an exhibition in a long time! I am planning to use spiked track for a planned 21mm gauge layout using stripwood sleepers spiked every 5th sleeper with soldered crossing wing rail assemblies.
  6. The Australian 3'6" gauge Metrovicks (WAGR X & XA Class) retained their Crossley engines to the end 1988 working narrow gauge Perth Suburban trains until services were electrified, few clouds of dirty smoke unlike the CIE engines.
  7. The first production batch of brake vans is substantially smaller than originally planned as a result of issues at the 3D printing stage which did not show up at the prototyping and test print stage. A small batch of 1950s vans is currently with our tampo printers waiting a slot in his production schedule. I am expecting to release the 1960/70s versions of the vans which are currently in the paint shop during September with transfer lettering as it would have been uneconomic to reproduce the ducket warning stripes using tampo printing. Pre-orders provides a reasonably accurate estimate of demand which will allow batch quantities to be increased/decreased as necessary. 23543 was lettered using tampo printing, alternative numbers would require a new printing tool and separate set up prohibitively expensive on small batch quantities. We are planning to finish the Ranks grain wagon with transfer lettering with running numbers (1-8) which may be applied by the customer (running numbers). We are not expecting to release the open wagons until the 1st quarter of 2022 and will certainly consider releasing these and other 'ordinary' goods wagons in fully decorated form with alternate running numbers or unlettered with a sheet of transfer lettering. Our 3D printing bureau is currently completing a number of test prints of the grain wagon to establish a representative sample of prints to identify potential production and quality assurance issues before we produce the production batch, we have also bought a high resolution desktop printer for prototyping and small batch production with a larger production machine expected late 2021 early 2022 which will give us greater control and predictability of our production schedules. I would forget speculating on our wagons we can always produce a batch of a particular wagon with minimal tooling and set up cost if there is evidence of sufficient demand.
  8. The models can be ordered/pre-ordered on our on-line shop https://jmdesignmodelrailways.com/. The first batch of Brake Vans in the 1950s grey are now sold out, the second batch (50s Grey)are currently with our tampo printers & we will start accepting orders once they are complete and assembled.
  9. Generally 2-3 weeks at the moment, recently an Airmail package from Markits arrived within 7 days and one from Wizard Models took 4 weeks. Van is packed in a presentation box within a stout cardboard shipping box with foam or bubble wrap packing. Packaging was a challenge as the traditional model railway style box with lid were unavailable and a vacuum formed insert prohibitively expensive, we used a medium density foam rubber to secure and protect the model. so should be ok.
  10. One significant point if you intend to 3D print track and point bases Templot uses two different gauges for modelling Irish 5'3" track in 4mm scale. 21mm gauge for P4 standards and 20.2mm if you use EMF or OO gauge standards, Martyn Wynne did much the same to achieve improved running with rtr OO rtr rolling stock reducing the gauge from 16.5mm to 16.2mm or EM-2. I struggled with Templot for a small EM gauge layout and have gone back to blown up EM gauge paper templates for 21mm gauge track. 3D printed point-bases are likely to be challenging particularly if there is no provision for adjustment in the location of crossing vee and switch assemblies. Personally I have hand laid pointwork in 1:1, 1:24 and 1:76 scales using timber, copper clad and ABS sleepers, using fangbolts, spikes, and individual chairs and soldered assembly and did not find it particularly difficult or time consuming, the main difference was that I needed a lot more people and machinery in 1:1. Chaired assembly either slide on or individually placed is a lot more time consuming and technically challenging than spiked or soldered assembly.
  11. Complete with what looks like a solid rake of "Silver Princes" stainless steel coaches As they say paper never refuses ink or electrons to get excited!
  12. Improved trading relations with the UK culminating in the Anglo-Irish Free Trade Agreement brought prosperity to rural Ireland in the 60s. My parents were surprised by the wealth of our "country cousins' when invited to weddings in County Galway during the 60s, wads of money was being splashed around like snuff at a wake, the women were dressed in the best Dublin & London fashion and the men driving new cars usually Mercedes, my mother and father felt like the poor city cousins instead! Most had shifted from mixed farming to dry stock which needed very little looking after, those with smaller farms usually had a part time job often driving for the local builders or agricultural merchant, most families were building a new modern streamlined bungalow to replace the old farmhouse. You can't go wrong with small black or brown Dexter cattle bred on farms in the West and shipped eastwards by rail for fattening in Meath or Kildare. Pilot loco from Galway working a short special to Athenry to connect with a main line goods from the smaller fairs or several A Class hauled specials with empty stock from Mullingar on the evening before the fair working the specials through to the North Wall for the bigger cattle fairs.
  13. The C Class may have been used for operational convenience, the Cs seems to have been worked quite intensively on the West Cork with two main line goods trains each way daily & the loco of the "Drimoleague Goods" working some of the Skibbereen & Baltimore passenger/mixed trains & the loco of one-of the Up Goods swapping over with the Clonakilty C for its weekly examination and maintenance. The main draw back of using an A on a daily West Cork goods there wouldn't have been another A to take over and haul the goods when it broke down, when a C broke down they could always rob a C off the second goods, a branch passenger train or a beet or a cattle special. Certainly a C in its original or B233-4, B201/201 Class for would be an ideal follow up for the IRM A Class, as much as I like the Sulzers they did not have the same wide sphere of use or variety of liveries to support a rtr model as the Metrovicks
  14. Talking to myself Opps!
  15. Kevin You threw up a bit of a curved ball there with batch and pre-order quantities of rtr wagons w Because of the low level of demand minimum expressions of interest/order quantities applied to the production of etched loco and rolling stock kits. We are committed to manufacturing the 3D printed wagons on our website (in much larger batches than 10!), the number of pre-orders will obviously influence the number of wagons produced and the number of models may be increased in response to demand. One of the benefits of 3D printing over traditional manufacture is that its fairly simple to produce a repeat of a model or produce custom models or one-off prints, the main constraint is the time consuming nature of clean up process and removal of the support structure. The anticipated release dates on the website are indicative only and are based on the current state of knowledge and will provide regular progress updates beginning with the decorated samples of Grain Wagons and Brake Vans with wheel logo expected mid-late August. We are establishing in house 3D printing capability while our current supplier is working to improve print quality with test prints of the Grain Wagon in different resins for approval mid July. We are planning to install in a high resolution desktop printer for prototyping and small batch production later this month with a production machine due late 2021/early 2022. While there are likely to be teething problems developing in-house printing capability capability should result in greater level of control over production and quality of the finished models. The ability to print in house with an external supplier as a back up for large orders will allow for more reliable production planning and manufacturing time frames. Not bad considering I only had an "idea" of 3D printing models in May 2020.
