  1. The class 487 trailer test build is now complete - This is in post-1980 blue livery at which date the aluminium paint on doors and ends was being replaced by white paint. Should be available from Radley Models in a couple of weeks. Delay in release due to having to replace the too flimsy resin bogies by lost wax brass ones. Additionally, the WM ends have had to be replaced by resin ones as the WM ones were cast by Graham Jones at NMRS and are obviously no longer available
  2. Companies like Heljan have tried that with their O gauge models but that hasn't helped in the slightest when dealing with an epidemic of defective split Delrin gears in their earlier locos. Pre-production samples seen by the commissioners might not always match what is actually produced as part of the main production batch and there isn't much you can do about it other than perhaps to use a different supplier next time as Graham_Muz says.
  3. Quality Control only matters to the manufacturer if the purchaser has the possibility of applying some form of sanction to the manufacturer. On the basis that the manufacturer: is a state-sponsored supplier [many of these 'private' companies are part of some PLA generals pension plan] is the only supplier is 6000 miles away has received full payment in advance of shipping goods will probably be manufacturing 3-pin plugs this time next week will have a different labour force this time next week There isn't anything that the purchaser can do about it and the purchaser knows it. Why is anyone surprised?
  4. Yes-the resin mixture doesn't stick to the plastic used in Lego blocks. Lego blocks also produce a pretty good seal between layers.
  5. Being a simple shape with a slight chamfer on the sloping edges, it lends itself to home resin casting. Here is the master with a few of its resin clones and the mould.
  6. Trig columns are a regular feature found in the UK countryside. Generally found on the tops of hills but can really be found almost anywhere that had [when erected in the 1930s] clear lines of sight to other exposed areas. These days their function has been supplanted by aerial photography and GPS mapping so the concrete columns can be a bit eroded and grubby. The most common sort is the tapering white concrete column about four foot tall which sits on a concrete box that is usually buried but may or may not be exposed - especially on eroded peat moors. They were used essentially as known positions from which theodolite sightings could be made to similar structures at some distance away. Each one contains a bronze bench mark and ID plate with a brass/bronze sighting arrangement on top. Most, but not all, are marked on OS maps by a small triangle with a dot in the centre. One that isn't marked is S2640 at grid SE 08013 00439 about a mile to the NE of Crowden. I measured this one [pictured below] and have produced a couple of 3D printed 4mm versions that now grace Churminster and Stowe Magna but 7mm cast resin versions will shortly be available from Radley Models. A picture of the 7mm master is attached.
  7. The 7mm Bedford RL should be available from Radley Models sometime in the next 7-10 days. A couple of photos of the completed kit are attached. This is a largely resin bodied kit with white metal wheels and lost wax brass castings for small delicate pieces. However, it also contains some etched parts - such as for the jerrican cages and the rear mudguards so a knowledge of folding and soldering thin etches would be useful. Thus I'd say, it's slightly more difficult than the average kit that I've designed. But it does make a nice model when finished!
  8. Given that the route Didcot-Oxford-Bletchley-Bedford-St Neots-Cambridge links the GWML with the OWW, WCML, MML and ECML as well as routes to Harwich, it seems pretty clear that freight traffic might multiply dramatically. The twelve or so LCs between Bletchley and Bedford coupled with the high water table along that route does suggest that some serious engineering will be required before it becomes viable as an orbital avoiding route from South Coast / West Coast to North or East Coast.
  9. For a long time the road hauliers didn't need to train their own drivers because of the large numbers of servicemen leaving HM Forces with an HGV licence. This is less and less common now.
  10. You are presumably unaware that the inquest on the victims of the Ufton Nervet HST derailment recorded that the driver of the car deliberately parked on the level crossing intending to commit suicide. In which case whatever sound the train made would have made no difference at all to the outcome. Thus, I fear that I don't understand the point you are trying to make.
  11. As of today, DS75 is now available in both 4mm and 7mm scales from Radley Models.
  12. Another factor in electrifying Didcot to Oxford presumably indicates an eventual electrification of Oxford to Milton Keynes/Bedford/Cambridge i.e., resurrecting the freight electric spine concept.
  13. You do have a rather agreeable way with words.
  14. Not the most difficult kit of all time - less couplings, a small piece of plastic card and the appropriate motor bogie, this is the kit of DS75. The resin bits are now appearing from the resin casters.
  15. B2X tender is well on its way - initially in 4mm but soon in 7mm [together with a 7mm C3]. This is the 4mm tender tank and water filler:
